cmake-modules - CMake Modules Reference

ALL MODULES

AddFileDependencies ADD_FILE_DEPENDENCIES(source_file depend_files...) Adds the given files as dependencies to source_file BundleUtilities Functions to help assemble a standalone bundle application. A collection of CMake utility functions useful for dealing with .app bundles on the Mac and bundle-like directories on any OS. The following functions are provided by this module: fixup_bundle copy_and_fixup_bundle verify_app get_bundle_main_executable get_dotapp_dir get_bundle_and_executable get_bundle_all_executables get_item_key get_item_rpaths clear_bundle_keys set_bundle_key_values get_bundle_keys copy_resolved_item_into_bundle copy_resolved_framework_into_bundle fixup_bundle_item verify_bundle_prerequisites verify_bundle_symlinks Requires CMake 2.6 or greater because it uses function, break and PARENT_SCOPE. Also depends on GetPrerequisites.cmake. FIXUP_BUNDLE(<app> <libs> <dirs>) Fix up a bundle in-place and make it standalone, such that it can be drag-n-drop copied to another machine and run on that machine as long as all of the system libraries are compat‐ ible. If you pass plugins to fixup_bundle as the libs parameter, you should install them or copy them into the bundle before calling fixup_bundle. The "libs" parameter is a list of libraries that must be fixed up, but that cannot be determined by otool output analysis. (i.e., plugins) Gather all the keys for all the executables and libraries in a bundle, and then, for each key, copy each prerequisite into the bundle. Then fix each one up according to its own list of prerequisites. Then clear all the keys and call verify_app on the final bundle to ensure that it is truly standalone. COPY_AND_FIXUP_BUNDLE(<src> <dst> <libs> <dirs>) Makes a copy of the bundle <src> at location <dst> and then fixes up the new copied bundle in-place at <dst>... VERIFY_APP(<app>) Verifies that an application <app> appears valid based on running analysis tools on it. Calls "message(FATAL_ERROR" if the application is not verified. GET_BUNDLE_MAIN_EXECUTABLE(<bundle> <result_var>) The result will be the full path name of the bundle's main executable file or an "error:" prefixed string if it could not be determined. GET_DOTAPP_DIR(<exe> <dotapp_dir_var>) Returns the nearest parent dir whose name ends with ".app" given the full path to an exe‐ cutable. If there is no such parent dir, then simply return the dir containing the exe‐ cutable. The returned directory may or may not exist. GET_BUNDLE_AND_EXECUTABLE(<app> <bundle_var> <executable_var> <valid_var>) Takes either a ".app" directory name or the name of an executable nested inside a ".app" directory and returns the path to the ".app" directory in <bundle_var> and the path to its main executable in <executable_var> GET_BUNDLE_ALL_EXECUTABLES(<bundle> <exes_var>) Scans the given bundle recursively for all executable files and accumulates them into a variable. GET_ITEM_KEY(<item> <key_var>) Given a file (item) name, generate a key that should be unique considering the set of libraries that need copying or fixing up to make a bundle standalone. This is essentially the file name including extension with "." replaced by "_" This key is used as a prefix for CMake variables so that we can associate a set of vari‐ ables with a given item based on its key. CLEAR_BUNDLE_KEYS(<keys_var>) Loop over the list of keys, clearing all the variables associated with each key. After the loop, clear the list of keys itself. Caller of get_bundle_keys should call clear_bundle_keys when done with list of keys. SET_BUNDLE_KEY_VALUES(<keys_var> <context> <item> <exepath> <dirs> <copyflag> [<rpaths>]) Add a key to the list (if necessary) for the given item. If added, also set all the vari‐ ables associated with that key. GET_BUNDLE_KEYS(<app> <libs> <dirs> <keys_var>) Loop over all the executable and library files within the bundle (and given as extra <libs>) and accumulate a list of keys representing them. Set values associated with each key such that we can loop over all of them and copy prerequisite libs into the bundle and then do appropriate install_name_tool fixups. COPY_RESOLVED_ITEM_INTO_BUNDLE(<resolved_item> <resolved_embedded_item>) Copy a resolved item into the bundle if necessary. Copy is not necessary if the resolved_item is "the same as" the resolved_embedded_item. COPY_RESOLVED_FRAMEWORK_INTO_BUNDLE(<resolved_item> <resolved_embedded_item>) Copy a resolved framework into the bundle if necessary. Copy is not necessary if the resolved_item is "the same as" the resolved_embedded_item. By default, BU_COPY_FULL_FRAMEWORK_CONTENTS is not set. If you want full frameworks embedded in your bundles, set BU_COPY_FULL_FRAMEWORK_CONTENTS to ON before calling fixup_bundle. By default, COPY_RESOLVED_FRAMEWORK_INTO_BUNDLE copies the framework dylib itself plus the framework Resources directory. FIXUP_BUNDLE_ITEM(<resolved_embedded_item> <exepath> <dirs>) Get the direct/non-system prerequisites of the resolved embedded item. For each prerequi‐ site, change the way it is referenced to the value of the _EMBEDDED_ITEM keyed variable for that prerequisite. (Most likely changing to an "@executable_path" style reference.) This function requires that the resolved_embedded_item be "inside" the bundle already. In other words, if you pass plugins to fixup_bundle as the libs parameter, you should install them or copy them into the bundle before calling fixup_bundle. The "libs" parameter is a list of libraries that must be fixed up, but that cannot be determined by otool output analysis. (i.e., plugins) Also, change the id of the item being fixed up to its own _EMBEDDED_ITEM value. Accumulate changes in a local variable and make one call to install_name_tool at the end of the function with all the changes at once. If the BU_CHMOD_BUNDLE_ITEMS variable is set then bundle items will be marked writable before install_name_tool tries to change them. VERIFY_BUNDLE_PREREQUISITES(<bundle> <result_var> <info_var>) Verifies that the sum of all prerequisites of all files inside the bundle are contained within the bundle or are "system" libraries, presumed to exist everywhere. VERIFY_BUNDLE_SYMLINKS(<bundle> <result_var> <info_var>) Verifies that any symlinks found in the bundle point to other files that are already also in the bundle... Anything that points to an external file causes this function to fail the verification. CheckCCompilerFlag Check whether the C compiler supports a given flag. CHECK_C_COMPILER_FLAG(<flag> <var>) <flag> - the compiler flag <var> - variable to store the result Will be created as an internal cache variable. This internally calls the check_c_source_compiles macro and sets CMAKE_REQUIRED_DEFINI‐ TIONS to <flag>. See help for CheckCSourceCompiles for a listing of variables that can otherwise modify the build. The result only tells that the compiler does not give an error message when it encounters the flag. If the flag has any effect or even a specific one is beyond the scope of this module. CheckCSourceCompiles Check if given C source compiles and links into an executable CHECK_C_SOURCE_COMPILES(<code> <var> [FAIL_REGEX <fail-regex>]) <code> - source code to try to compile, must define 'main' <var> - variable to store whether the source code compiled Will be created as an internal cache variable. <fail-regex> - fail if test output matches this regex The following variables may be set before calling this macro to modify the way the check is run: CMAKE_REQUIRED_FLAGS = string of compile command line flags CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar) CMAKE_REQUIRED_INCLUDES = list of include directories CMAKE_REQUIRED_LIBRARIES = list of libraries to link CMAKE_REQUIRED_QUIET = execute quietly without messages CheckCSourceRuns Check if the given C source code compiles and runs. CHECK_C_SOURCE_RUNS(<code> <var>) <code> - source code to try to compile <var> - variable to store the result (1 for success, empty for failure) Will be created as an internal cache variable. The following variables may be set before calling this macro to modify the way the check is run: CMAKE_REQUIRED_FLAGS = string of compile command line flags CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar) CMAKE_REQUIRED_INCLUDES = list of include directories CMAKE_REQUIRED_LIBRARIES = list of libraries to link CMAKE_REQUIRED_QUIET = execute quietly without messages CheckCXXCompilerFlag Check whether the CXX compiler supports a given flag. CHECK_CXX_COMPILER_FLAG(<flag> <var>) <flag> - the compiler flag <var> - variable to store the result This internally calls the check_cxx_source_compiles macro and sets CMAKE_REQUIRED_DEFINI‐ TIONS to <flag>. See help for CheckCXXSourceCompiles for a listing of variables that can otherwise modify the build. The result only tells that the compiler does not give an error message when it encounters the flag. If the flag has any effect or even a specific one is beyond the scope of this module. CheckCXXSourceCompiles Check if given C++ source compiles and links into an executable CHECK_CXX_SOURCE_COMPILES(<code> <var> [FAIL_REGEX <fail-regex>]) <code> - source code to try to compile, must define 'main' <var> - variable to store whether the source code compiled Will be created as an internal cache variable. <fail-regex> - fail if test output matches this regex The following variables may be set before calling this macro to modify the way the check is run: CMAKE_REQUIRED_FLAGS = string of compile command line flags CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar) CMAKE_REQUIRED_INCLUDES = list of include directories CMAKE_REQUIRED_LIBRARIES = list of libraries to link CMAKE_REQUIRED_QUIET = execute quietly without messages CheckCXXSourceRuns Check if the given C++ source code compiles and runs. CHECK_CXX_SOURCE_RUNS(<code> <var>) <code> - source code to try to compile <var> - variable to store the result (1 for success, empty for failure) Will be created as an internal cache variable. The following variables may be set before calling this macro to modify the way the check is run: CMAKE_REQUIRED_FLAGS = string of compile command line flags CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar) CMAKE_REQUIRED_INCLUDES = list of include directories CMAKE_REQUIRED_LIBRARIES = list of libraries to link CMAKE_REQUIRED_QUIET = execute quietly without messages CheckCXXSymbolExists Check if a symbol exists as a function, variable, or macro in C++ CHECK_CXX_SYMBOL_EXISTS(<symbol> <files> <variable>) Check that the <symbol> is available after including given header <files> and store the result in a <variable>. Specify the list of files in one argument as a semicolon-sepa‐ rated list. CHECK_CXX_SYMBOL_EXISTS() can be used to check in C++ files, as opposed to CHECK_SYMBOL_EXISTS(), which works only for C. If the header files define the symbol as a macro it is considered available and assumed to work. If the header files declare the symbol as a function or variable then the symbol must also be available for linking. If the symbol is a type or enum value it will not be recognized (consider using CheckTypeSize or CheckCSourceCompiles). The following variables may be set before calling this macro to modify the way the check is run: CMAKE_REQUIRED_FLAGS = string of compile command line flags CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar) CMAKE_REQUIRED_INCLUDES = list of include directories CMAKE_REQUIRED_LIBRARIES = list of libraries to link CMAKE_REQUIRED_QUIET = execute quietly without messages CheckFortranCompilerFlag Check whether the Fortran compiler supports a given flag. CHECK_Fortran_COMPILER_FLAG(<flag> <var>) <flag> - the compiler flag <var> - variable to store the result Will be created as an internal cache variable. This internally calls the check_fortran_source_compiles macro and sets CMAKE_REQUIRED_DEF‐ INITIONS to <flag>. See help for CheckFortranSourceCompiles for a listing of variables that can otherwise modify the build. The result only tells that the compiler does not give an error message when it encounters the flag. If the flag has any effect or even a specific one is beyond the scope of this module. CheckFortranFunctionExists macro which checks if the Fortran function exists CHECK_FORTRAN_FUNCTION_EXISTS(FUNCTION VARIABLE) FUNCTION - the name of the Fortran function VARIABLE - variable to store the result Will be created as an internal cache variable. The following variables may be set before calling this macro to modify the way the check is run: CMAKE_REQUIRED_LIBRARIES = list of libraries to link CheckFortranSourceCompiles Check if given Fortran source compiles and links into an executable: CHECK_Fortran_SOURCE_COMPILES(<code> <var> [FAIL_REGEX <fail-regex>]) The arguments are: <code> Source code to try to compile. It must define a PROGRAM entry point. <var> Variable to store whether the source code compiled. Will be created as an internal cache variable. <fail-regex> Fail if test output matches this regex. The following variables may be set before calling this macro to modify the way the check is run: CMAKE_REQUIRED_FLAGS = string of compile command line flags CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar) CMAKE_REQUIRED_INCLUDES = list of include directories CMAKE_REQUIRED_LIBRARIES = list of libraries to link CMAKE_REQUIRED_QUIET = execute quietly without messages CheckFunctionExists Check if a C function can be linked CHECK_FUNCTION_EXISTS(<function> <variable>) Check that the <function> is provided by libraries on the system and store the result in a <variable>. This does not verify that any system header file declares the function, only that it can be found at link time (consider using CheckSymbolExists). <variable> will be created as an internal cache variable. The following variables may be set before calling this macro to modify the way the check is run: CMAKE_REQUIRED_FLAGS = string of compile command line flags CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar) CMAKE_REQUIRED_INCLUDES = list of include directories CMAKE_REQUIRED_LIBRARIES = list of libraries to link CMAKE_REQUIRED_QUIET = execute quietly without messages CheckIncludeFileCXX Provides a macro to check if a header file can be included in CXX. CHECK_INCLUDE_FILE_CXX CHECK_INCLUDE_FILE_CXX(<include> <variable> [<flags>]) Check if the given <include> file may be included in a CXX source file and store the result in an internal cache entry named <variable>. The optional third argu‐ ment may be used to add compilation flags to the check (or use CMAKE_REQUIRED_FLAGS below). The following variables may be set before calling this macro to modify the way the check is run: CMAKE_REQUIRED_FLAGS string of compile command line flags CMAKE_REQUIRED_DEFINITIONS list of macros to define (-DFOO=bar) CMAKE_REQUIRED_INCLUDES list of include directories CMAKE_REQUIRED_QUIET execute quietly without messages See modules CheckIncludeFile and CheckIncludeFiles to check for one or more C headers. CheckIncludeFile Provides a macro to check if a header file can be included in C. CHECK_INCLUDE_FILE CHECK_INCLUDE_FILE(<include> <variable> [<flags>]) Check if the given <include> file may be included in a C source file and store the result in an internal cache entry named <variable>. The optional third argument may be used to add compilation flags to the check (or use CMAKE_REQUIRED_FLAGS below). The following variables may be set before calling this macro to modify the way the check is run: CMAKE_REQUIRED_FLAGS string of compile command line flags CMAKE_REQUIRED_DEFINITIONS list of macros to define (-DFOO=bar) CMAKE_REQUIRED_INCLUDES list of include directories CMAKE_REQUIRED_QUIET execute quietly without messages See the CheckIncludeFiles module to check for multiple headers at once. See the CheckIn‐ cludeFileCXX module to check for headers using the CXX language. CheckIncludeFiles Provides a macro to check if a list of one or more header files can be included together in C. CHECK_INCLUDE_FILES CHECK_INCLUDE_FILES("<includes>" <variable>) Check if the given <includes> list may be included together in a C source file and store the result in an internal cache entry named <variable>. Specify the <includes> argument as a ;-list of header file names. The following variables may be set before calling this macro to modify the way the check is run: CMAKE_REQUIRED_FLAGS string of compile command line flags CMAKE_REQUIRED_DEFINITIONS list of macros to define (-DFOO=bar) CMAKE_REQUIRED_INCLUDES list of include directories CMAKE_REQUIRED_QUIET execute quietly without messages See modules CheckIncludeFile and CheckIncludeFileCXX to check for a single header file in C or CXX languages. CheckLanguage Check if a language can be enabled Usage: check_language(<lang>) where <lang> is a language that may be passed to enable_language() such as "Fortran". If CMAKE_<lang>_COMPILER is already defined the check does nothing. Otherwise it tries enabling the language in a test project. The result is cached in CMAKE_<lang>_COMPILER as the compiler that was found, or NOTFOUND if the language cannot be enabled. Example: check_language(Fortran) if(CMAKE_Fortran_COMPILER) enable_language(Fortran) else() message(STATUS "No Fortran support") endif() CheckLibraryExists Check if the function exists. CHECK_LIBRARY_EXISTS (LIBRARY FUNCTION LOCATION VARIABLE) LIBRARY - the name of the library you are looking for FUNCTION - the name of the function LOCATION - location where the library should be found VARIABLE - variable to store the result Will be created as an internal cache variable. The following variables may be set before calling this macro to modify the way the check is run: CMAKE_REQUIRED_FLAGS = string of compile command line flags CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar) CMAKE_REQUIRED_LIBRARIES = list of libraries to link CMAKE_REQUIRED_QUIET = execute quietly without messages CheckPrototypeDefinition Check if the protoype we expect is correct. check_prototype_definition(FUNCTION PROTOTYPE RETURN HEADER VARIABLE) FUNCTION - The name of the function (used to check if prototype exists) PROTOTYPE- The prototype to check. RETURN - The return value of the function. HEADER - The header files required. VARIABLE - The variable to store the result. Will be created as an internal cache variable. Example: check_prototype_definition(getpwent_r "struct passwd *getpwent_r(struct passwd *src, char *buf, int buflen)" "NULL" "unistd.h;pwd.h" SOLARIS_GETPWENT_R) The following variables may be set before calling this macro to modify the way the check is run: CMAKE_REQUIRED_FLAGS = string of compile command line flags CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar) CMAKE_REQUIRED_INCLUDES = list of include directories CMAKE_REQUIRED_LIBRARIES = list of libraries to link CMAKE_REQUIRED_QUIET = execute quietly without messages CheckStructHasMember Check if the given struct or class has the specified member variable CHECK_STRUCT_HAS_MEMBER(<struct> <member> <header> <variable> [LANGUAGE <language>]) <struct> - the name of the struct or class you are interested in <member> - the member which existence you want to check <header> - the header(s) where the prototype should be declared <variable> - variable to store the result <language> - the compiler to use (C or CXX) The following variables may be set before calling this macro to modify the way the check is run: CMAKE_REQUIRED_FLAGS = string of compile command line flags CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar) CMAKE_REQUIRED_INCLUDES = list of include directories CMAKE_REQUIRED_LIBRARIES = list of libraries to link CMAKE_REQUIRED_QUIET = execute quietly without messages Example: CHECK_STRUCT_HAS_MEMBER("struct timeval" tv_sec sys/select.h HAVE_TIMEVAL_TV_SEC LANGUAGE C) CheckSymbolExists Check if a symbol exists as a function, variable, or macro CHECK_SYMBOL_EXISTS(<symbol> <files> <variable>) Check that the <symbol> is available after including given header <files> and store the result in a <variable>. Specify the list of files in one argument as a semicolon-sepa‐ rated list. <variable> will be created as an internal cache variable. If the header files define the symbol as a macro it is considered available and assumed to work. If the header files declare the symbol as a function or variable then the symbol must also be available for linking. If the symbol is a type or enum value it will not be recognized (consider using CheckTypeSize or CheckCSourceCompiles). If the check needs to be done in C++, consider using CHECK_CXX_SYMBOL_EXISTS(), which does the same as CHECK_SYMBOL_EXISTS(), but in C++. The following variables may be set before calling this macro to modify the way the check is run: CMAKE_REQUIRED_FLAGS = string of compile command line flags CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar) CMAKE_REQUIRED_INCLUDES = list of include directories CMAKE_REQUIRED_LIBRARIES = list of libraries to link CMAKE_REQUIRED_QUIET = execute quietly without messages CheckTypeSize Check sizeof a type CHECK_TYPE_SIZE(TYPE VARIABLE [BUILTIN_TYPES_ONLY] [LANGUAGE <language>]) Check if the type exists and determine its size. On return, "HAVE_${VARIABLE}" holds the existence of the type, and "${VARIABLE}" holds one of the following: <size> = type has non-zero size <size> "0" = type has arch-dependent size (see below) "" = type does not exist Both HAVE_${VARIABLE} and ${VARIABLE} will be created as internal cache variables. Furthermore, the variable "${VARIABLE}_CODE" holds C preprocessor code to define the macro "${VARIABLE}" to the size of the type, or leave the macro undefined if the type does not exist. The variable "${VARIABLE}" may be "0" when CMAKE_OSX_ARCHITECTURES has multiple architec‐ tures for building OS X universal binaries. This indicates that the type size varies across architectures. In this case "${VARIABLE}_CODE" contains C preprocessor tests map‐ ping from each architecture macro to the corresponding type size. The list of architec‐ ture macros is stored in "${VARIABLE}_KEYS", and the value for each key is stored in "${VARIABLE}-${KEY}". If the BUILTIN_TYPES_ONLY option is not given, the macro checks for headers <sys/types.h>, <stdint.h>, and <stddef.h>, and saves results in HAVE_SYS_TYPES_H, HAVE_STDINT_H, and HAVE_STDDEF_H. The type size check automatically includes the available headers, thus supporting checks of types defined in the headers. If LANGUAGE is set, the specified compiler will be used to perform the check. Acceptable values are C and CXX Despite the name of the macro you may use it to check the size of more complex expres‐ sions, too. To check e.g. for the size of a struct member you can do something like this: check_type_size("((struct something*)0)->member" SIZEOF_MEMBER) The following variables may be set before calling this macro to modify the way the check is run: CMAKE_REQUIRED_FLAGS = string of compile command line flags CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar) CMAKE_REQUIRED_INCLUDES = list of include directories CMAKE_REQUIRED_LIBRARIES = list of libraries to link CMAKE_REQUIRED_QUIET = execute quietly without messages CMAKE_EXTRA_INCLUDE_FILES = list of extra headers to include CheckVariableExists Check if the variable exists. CHECK_VARIABLE_EXISTS(VAR VARIABLE) VAR - the name of the variable VARIABLE - variable to store the result Will be created as an internal cache variable. This macro is only for C variables. The following variables may be set before calling this macro to modify the way the check is run: CMAKE_REQUIRED_FLAGS = string of compile command line flags CMAKE_REQUIRED_DEFINITIONS = list of macros to define (-DFOO=bar) CMAKE_REQUIRED_LIBRARIES = list of libraries to link CMAKE_REQUIRED_QUIET = execute quietly without messages CMakeAddFortranSubdirectory Use MinGW gfortran from VS if a fortran compiler is not found. The 'add_fortran_subdirectory' function adds a subdirectory to a project that contains a fortran only sub-project. The module will check the current compiler and see if it can support fortran. If no fortran compiler is found and the compiler is MSVC, then this mod‐ ule will find the MinGW gfortran. It will then use an external project to build with the MinGW tools. It will also create imported targets for the libraries created. This will only work if the fortran code is built into a dll, so BUILD_SHARED_LIBS is turned on in the project. In addition the CMAKE_GNUtoMS option is set to on, so that the MS .lib files are created. Usage is as follows: cmake_add_fortran_subdirectory( <subdir> # name of subdirectory PROJECT <project_name> # project name in subdir top CMakeLists.txt ARCHIVE_DIR <dir> # dir where project places .lib files RUNTIME_DIR <dir> # dir where project places .dll files LIBRARIES <lib>... # names of library targets to import LINK_LIBRARIES # link interface libraries for LIBRARIES [LINK_LIBS <lib> <dep>...]... CMAKE_COMMAND_LINE ... # extra command line flags to pass to cmake NO_EXTERNAL_INSTALL # skip installation of external project ) Relative paths in ARCHIVE_DIR and RUNTIME_DIR are interpreted with respect to the build directory corresponding to the source directory in which the function is invoked. Limitations: NO_EXTERNAL_INSTALL is required for forward compatibility with a future version that sup‐ ports installation of the external project binaries during "make install". CMakeBackwardCompatibilityCXX define a bunch of backwards compatibility variables CMAKE_ANSI_CXXFLAGS - flag for ansi c++ CMAKE_HAS_ANSI_STRING_STREAM - has <strstream> include(TestForANSIStreamHeaders) include(CheckIncludeFileCXX) include(TestForSTDNamespace) include(TestForANSIForScope) CMakeDependentOption Macro to provide an option dependent on other options. This macro presents an option to the user only if a set of other conditions are true. When the option is not presented a default value is used, but any value set by the user is preserved for when the option is presented again. Example invocation: CMAKE_DEPENDENT_OPTION(USE_FOO "Use Foo" ON "USE_BAR;NOT USE_ZOT" OFF) If USE_BAR is true and USE_ZOT is false, this provides an option called USE_FOO that defaults to ON. Otherwise, it sets USE_FOO to OFF. If the status of USE_BAR or USE_ZOT ever changes, any value for the USE_FOO option is saved so that when the option is re-enabled it retains its old value. CMakeDetermineVSServicePack Deprecated. Do not use. The functionality of this module has been superseded by the CMAKE_<LANG>_COMPILER_VERSION variable that contains the compiler version number. Determine the Visual Studio service pack of the 'cl' in use. Usage: if(MSVC) include(CMakeDetermineVSServicePack) DetermineVSServicePack( my_service_pack ) if( my_service_pack ) message(STATUS "Detected: ${my_service_pack}") endif() endif() Function DetermineVSServicePack sets the given variable to one of the following values or an empty string if unknown: vc80, vc80sp1 vc90, vc90sp1 vc100, vc100sp1 vc110, vc110sp1, vc110sp2, vc110sp3, vc110sp4 CMakeExpandImportedTargets Deprecated. Do not use. This module was once needed to expand imported targets to the underlying libraries they reference on disk for use with the try_compile() and try_run() commands. These commands now support imported libraries in their LINK_LIBRARIES options (since CMake 2.8.11 for try_compile() and since CMake 3.2 for try_run()). This module does not support the policy CMP0022 NEW behavior or use of the INTER‐ FACE_LINK_LIBRARIES property because generator expressions cannot be evaluated during con‐ figuration. CMAKE_EXPAND_IMPORTED_TARGETS(<var> LIBRARIES lib1 lib2...libN [CONFIGURATION <config>]) CMAKE_EXPAND_IMPORTED_TARGETS() takes a list of libraries and replaces all imported tar‐ gets contained in this list with their actual file paths of the referenced libraries on disk, including the libraries from their link interfaces. If a CONFIGURATION is given, it uses the respective configuration of the imported targets if it exists. If no CONFIGURA‐ TION is given, it uses the first configuration from ${CMAKE_CONFIGURATION_TYPES} if set, otherwise ${CMAKE_BUILD_TYPE}. cmake_expand_imported_targets(expandedLibs LIBRARIES ${CMAKE_REQUIRED_LIBRARIES} CONFIGURATION "${CMAKE_TRY_COMPILE_CONFIGURATION}" ) CMakeFindDependencyMacro find_dependency(<dep> [<version> [EXACT]]) find_dependency() wraps a find_package() call for a package dependency. It is designed to be used in a <package>Config.cmake file, and it forwards the correct parameters for EXACT, QUIET and REQUIRED which were passed to the original find_package() call. It also sets an informative diagnostic message if the dependency could not be found. CMakeFindFrameworks helper module to find OSX frameworks CMakeFindPackageMode This file is executed by cmake when invoked with --find-package. It expects that the fol‐ lowing variables are set using -D: NAME name of the package COMPILER_ID the CMake compiler ID for which the result is, i.e. GNU/Intel/Clang/MSVC, etc. LANGUAGE language for which the result will be used, i.e. C/CXX/Fortan/ASM MODE EXIST only check for existence of the given package COMPILE print the flags needed for compiling an object file which uses the given package LINK print the flags needed for linking when using the given package QUIET if TRUE, don't print anything CMakeForceCompiler Discouraged. Avoid using this module if possible. It will be deprecated by a future ver‐ sion of CMake once alternatives have been provided for all toolchain file use cases. The macros provided by this module were once intended for use by cross-compiling toolchain files when CMake was not able to automatically detect the compiler identification. Since the introduction of this module, CMake's compiler identification capabilities have improved and can now be taught to recognize any compiler. Furthermore, the suite of information CMake detects from a compiler is now too extensive to be provided by toolchain files using these macros. The only known remaining use case for these macros is to write toolchain files for cross-compilers that cannot link binaries without special flags or custom linker scripts. These macros cause CMake to skip checks it normally performs as part of enabling a lan‐ guage and introspecting the toolchain. However, skipping these checks may limit some gen‐ eration functionality. ---- Macro CMAKE_FORCE_C_COMPILER has the following signature: CMAKE_FORCE_C_COMPILER(<compiler> <compiler-id>) It sets CMAKE_C_COMPILER to the given compiler and the cmake internal variable CMAKE_C_COMPILER_ID to the given compiler-id. It also bypasses the check for working com‐ piler and basic compiler information tests. Macro CMAKE_FORCE_CXX_COMPILER has the following signature: CMAKE_FORCE_CXX_COMPILER(<compiler> <compiler-id>) It sets CMAKE_CXX_COMPILER to the given compiler and the cmake internal variable CMAKE_CXX_COMPILER_ID to the given compiler-id. It also bypasses the check for working compiler and basic compiler information tests. Macro CMAKE_FORCE_Fortran_COMPILER has the following signature: CMAKE_FORCE_Fortran_COMPILER(<compiler> <compiler-id>) It sets CMAKE_Fortran_COMPILER to the given compiler and the cmake internal variable CMAKE_Fortran_COMPILER_ID to the given compiler-id. It also bypasses the check for work‐ ing compiler and basic compiler information tests. So a simple toolchain file could look like this: include (CMakeForceCompiler) set(CMAKE_SYSTEM_NAME Generic) CMAKE_FORCE_C_COMPILER (chc12 MetrowerksHicross) CMAKE_FORCE_CXX_COMPILER (chc12 MetrowerksHicross) CMakeGraphVizOptions The builtin graphviz support of CMake. Variables specific to the graphviz support CMake can generate graphviz files, showing the dependencies between the targets in a project and also external libraries which are linked against. When CMake is run with the --graphviz=foo option, it will produce · a foo.dot file showing all dependencies in the project · a foo.dot.<target> file for each target, file showing on which other targets the respec‐ tive target depends · a foo.dot.<target>.dependers file, showing which other targets depend on the respective target This can result in huge graphs. Using the file CMakeGraphVizOptions.cmake the look and content of the generated graphs can be influenced. This file is searched first in ${CMAKE_BINARY_DIR} and then in ${CMAKE_SOURCE_DIR}. If found, it is read and the vari‐ ables set in it are used to adjust options for the generated graphviz files. GRAPHVIZ_GRAPH_TYPE The graph type · Mandatory : NO · Default : "digraph" GRAPHVIZ_GRAPH_NAME The graph name. · Mandatory : NO · Default : "GG" GRAPHVIZ_GRAPH_HEADER The header written at the top of the graphviz file. · Mandatory : NO · Default : "node [n fontsize = "12"];" GRAPHVIZ_NODE_PREFIX The prefix for each node in the graphviz file. · Mandatory : NO · Default : "node" GRAPHVIZ_EXECUTABLES Set this to FALSE to exclude executables from the generated graphs. · Mandatory : NO · Default : TRUE GRAPHVIZ_STATIC_LIBS Set this to FALSE to exclude static libraries from the generated graphs. · Mandatory : NO · Default : TRUE GRAPHVIZ_SHARED_LIBS Set this to FALSE to exclude shared libraries from the generated graphs. · Mandatory : NO · Default : TRUE GRAPHVIZ_MODULE_LIBS Set this to FALSE to exclude module libraries from the generated graphs. · Mandatory : NO · Default : TRUE GRAPHVIZ_EXTERNAL_LIBS Set this to FALSE to exclude external libraries from the generated graphs. · Mandatory : NO · Default : TRUE GRAPHVIZ_IGNORE_TARGETS A list of regular expressions for ignoring targets. · Mandatory : NO · Default : empty GRAPHVIZ_GENERATE_PER_TARGET Set this to FALSE to exclude per target graphs foo.dot.<target>. · Mandatory : NO · Default : TRUE GRAPHVIZ_GENERATE_DEPENDERS Set this to FALSE to exclude depender graphs foo.dot.<target>.dependers. · Mandatory : NO · Default : TRUE CMakePackageConfigHelpers Helpers functions for creating config files that can be included by other projects to find and use a package. Adds the configure_package_config_file() and write_basic_package_version_file() commands. Generating a Package Configuration File configure_package_config_file Create a config file for a project: configure_package_config_file(<input> <output> INSTALL_DESTINATION <path> [PATH_VARS <var1> <var2> ... <varN>] [NO_SET_AND_CHECK_MACRO] [NO_CHECK_REQUIRED_COMPONENTS_MACRO] [INSTALL_PREFIX <path>] ) configure_package_config_file() should be used instead of the plain configure_file() com‐ mand when creating the <Name>Config.cmake or <Name>-config.cmake file for installing a project or library. It helps making the resulting package relocatable by avoiding hard‐ coded paths in the installed Config.cmake file. In a FooConfig.cmake file there may be code like this to make the install destinations know to the using project: set(FOO_INCLUDE_DIR "@CMAKE_INSTALL_FULL_INCLUDEDIR@" ) set(FOO_DATA_DIR "@CMAKE_INSTALL_PREFIX@/@RELATIVE_DATA_INSTALL_DIR@" ) set(FOO_ICONS_DIR "@CMAKE_INSTALL_PREFIX@/share/icons" ) ...logic to determine installedPrefix from the own location... set(FOO_CONFIG_DIR "${installedPrefix}/@CONFIG_INSTALL_DIR@" ) All 4 options shown above are not sufficient, since the first 3 hardcode the absolute directory locations, and the 4th case works only if the logic to determine the installed‐ Prefix is correct, and if CONFIG_INSTALL_DIR contains a relative path, which in general cannot be guaranteed. This has the effect that the resulting FooConfig.cmake file would work poorly under Windows and OSX, where users are used to choose the install location of a binary package at install time, independent from how CMAKE_INSTALL_PREFIX was set at build/cmake time. Using configure_package_config_file helps. If used correctly, it makes the resulting FooConfig.cmake file relocatable. Usage: 1. write a FooConfig.cmake.in file as you are used to 2. insert a line containing only the string @PACKAGE_INIT@ 3. instead of set(FOO_DIR "@SOME_INSTALL_DIR@"), use set(FOO_DIR "@PACK‐ AGE_SOME_INSTALL_DIR@") (this must be after the @PACKAGE_INIT@ line) 4. instead of using the normal configure_file(), use configure_package_config_file() The <input> and <output> arguments are the input and output file, the same way as in con‐ figure_file(). The <path> given to INSTALL_DESTINATION must be the destination where the FooConfig.cmake file will be installed to. This path can either be absolute, or relative to the INSTALL_PREFIX path. The variables <var1> to <varN> given as PATH_VARS are the variables which contain install destinations. For each of them the macro will create a helper variable PACKAGE_<var...>. These helper variables must be used in the FooConfig.cmake.in file for setting the installed location. They are calculated by configure_package_config_file so that they are always relative to the installed location of the package. This works both for relative and also for absolute locations. For absolute locations it works only if the absolute location is a subdirectory of INSTALL_PREFIX. If the INSTALL_PREFIX argument is passed, this is used as base path to calculate all the relative paths. The <path> argument must be an absolute path. If this argument is not passed, the CMAKE_INSTALL_PREFIX variable will be used instead. The default value is good when generating a FooConfig.cmake file to use your package from the install tree. When generating a FooConfig.cmake file to use your package from the build tree this option should be used. By default configure_package_config_file also generates two helper macros, set_and_check() and check_required_components() into the FooConfig.cmake file. set_and_check() should be used instead of the normal set() command for setting directories and file locations. Additionally to setting the variable it also checks that the refer‐ enced file or directory actually exists and fails with a FATAL_ERROR otherwise. This makes sure that the created FooConfig.cmake file does not contain wrong references. When using the NO_SET_AND_CHECK_MACRO, this macro is not generated into the FooConfig.cmake file. check_required_components(<package_name>) should be called at the end of the FooCon‐ fig.cmake file if the package supports components. This macro checks whether all requested, non-optional components have been found, and if this is not the case, sets the Foo_FOUND variable to FALSE, so that the package is considered to be not found. It does that by testing the Foo_<Component>_FOUND variables for all requested required components. When using the NO_CHECK_REQUIRED_COMPONENTS_MACRO option, this macro is not generated into the FooConfig.cmake file. For an example see below the documentation for write_basic_package_version_file(). Generating a Package Version File write_basic_package_version_file Create a version file for a project: write_basic_package_version_file(<filename> [VERSION <major.minor.patch>] COMPATIBILITY <AnyNewerVersion|SameMajorVersion|ExactVersion> ) Writes a file for use as <package>ConfigVersion.cmake file to <filename>. See the docu‐ mentation of find_package() for details on this. <filename> is the output filename, it should be in the build tree. <major.minor.patch> is the version number of the project to be installed. If no VERSION is given, the PROJECT_VERSION variable is used. If this hasn't been set, it errors out. The COMPATIBILITY mode AnyNewerVersion means that the installed package version will be considered compatible if it is newer or exactly the same as the requested version. This mode should be used for packages which are fully backward compatible, also across major versions. If SameMajorVersion is used instead, then the behaviour differs from AnyNew‐ erVersion in that the major version number must be the same as requested, e.g. version 2.0 will not be considered compatible if 1.0 is requested. This mode should be used for packages which guarantee backward compatibility within the same major version. If ExactVersion is used, then the package is only considered compatible if the requested ver‐ sion matches exactly its own version number (not considering the tweak version). For example, version 1.2.3 of a package is only considered compatible to requested version 1.2.3. This mode is for packages without compatibility guarantees. If your project has more elaborated version matching rules, you will need to write your own custom ConfigVer‐ sion.cmake file instead of using this macro. Internally, this macro executes configure_file() to create the resulting version file. Depending on the COMPATIBLITY, either the file BasicConfigVersion-SameMajorVer‐ sion.cmake.in or BasicConfigVersion-AnyNewerVersion.cmake.in is used. Please note that these two files are internal to CMake and you should not call configure_file() on them yourself, but they can be used as starting point to create more sophisticted custom Con‐ figVersion.cmake files. Example Generating Package Files Example using both configure_package_config_file() and write_basic_package_version_file(): CMakeLists.txt: set(INCLUDE_INSTALL_DIR include/ ... CACHE ) set(LIB_INSTALL_DIR lib/ ... CACHE ) set(SYSCONFIG_INSTALL_DIR etc/foo/ ... CACHE ) ... include(CMakePackageConfigHelpers) configure_package_config_file(FooConfig.cmake.in ${CMAKE_CURRENT_BINARY_DIR}/FooConfig.cmake INSTALL_DESTINATION ${LIB_INSTALL_DIR}/Foo/cmake PATH_VARS INCLUDE_INSTALL_DIR SYSCONFIG_INSTALL_DIR) write_basic_package_version_file( ${CMAKE_CURRENT_BINARY_DIR}/FooConfigVersion.cmake VERSION 1.2.3 COMPATIBILITY SameMajorVersion ) install(FILES ${CMAKE_CURRENT_BINARY_DIR}/FooConfig.cmake ${CMAKE_CURRENT_BINARY_DIR}/FooConfigVersion.cmake DESTINATION ${LIB_INSTALL_DIR}/Foo/cmake ) FooConfig.cmake.in: set(FOO_VERSION x.y.z) ... @PACKAGE_INIT@ ... set_and_check(FOO_INCLUDE_DIR "@PACKAGE_INCLUDE_INSTALL_DIR@") set_and_check(FOO_SYSCONFIG_DIR "@PACKAGE_SYSCONFIG_INSTALL_DIR@") check_required_components(Foo) CMakeParseArguments This module once implemented the cmake_parse_arguments() command that is now implemented natively by CMake. It is now an empty placeholder for compatibility with projects that include it to get the command from CMake 3.4 and lower. CMakePrintHelpers Convenience macros for printing properties and variables, useful e.g. for debugging. CMAKE_PRINT_PROPERTIES([TARGETS target1 .. targetN] [SOURCES source1 .. sourceN] [DIRECTORIES dir1 .. dirN] [TESTS test1 .. testN] [CACHE_ENTRIES entry1 .. entryN] PROPERTIES prop1 .. propN ) This macro prints the values of the properties of the given targets, source files, direc‐ tories, tests or cache entries. Exactly one of the scope keywords must be used. Example: cmake_print_properties(TARGETS foo bar PROPERTIES LOCATION INTERFACE_INCLUDE_DIRS) This will print the LOCATION and INTERFACE_INCLUDE_DIRS properties for both targets foo and bar. CMAKE_PRINT_VARIABLES(var1 var2 .. varN) This macro will print the name of each variable followed by its value. Example: cmake_print_variables(CMAKE_C_COMPILER CMAKE_MAJOR_VERSION DOES_NOT_EXIST) Gives: -- CMAKE_C_COMPILER="/usr/bin/gcc" ; CMAKE_MAJOR_VERSION="2" ; DOES_NOT_EXIST="" CMakePrintSystemInformation print system information This file can be used for diagnostic purposes just include it in a project to see various internal CMake variables. CMakePushCheckState This module defines three macros: CMAKE_PUSH_CHECK_STATE() CMAKE_POP_CHECK_STATE() and CMAKE_RESET_CHECK_STATE() These macros can be used to save, restore and reset (i.e., clear contents) the state of the variables CMAKE_REQUIRED_FLAGS, CMAKE_REQUIRED_DEFINITIONS, CMAKE_REQUIRED_LIBRARIES and CMAKE_REQUIRED_INCLUDES used by the various Check-files com‐ ing with CMake, like e.g. check_function_exists() etc. The variable contents are pushed on a stack, pushing multiple times is supported. This is useful e.g. when executing such tests in a Find-module, where they have to be set, but after the Find-module has been exe‐ cuted they should have the same value as they had before. CMAKE_PUSH_CHECK_STATE() macro receives optional argument RESET. Whether it's specified, CMAKE_PUSH_CHECK_STATE() will set all CMAKE_REQUIRED_* variables to empty values, same as CMAKE_RESET_CHECK_STATE() call will do. Usage: cmake_push_check_state(RESET) set(CMAKE_REQUIRED_DEFINITIONS -DSOME_MORE_DEF) check_function_exists(...) cmake_reset_check_state() set(CMAKE_REQUIRED_DEFINITIONS -DANOTHER_DEF) check_function_exists(...) cmake_pop_check_state() CMakeVerifyManifest CMakeVerifyManifest.cmake This script is used to verify that embeded manifests and side by side manifests for a project match. To run this script, cd to a directory and run the script with cmake -P. On the command line you can pass in versions that are OK even if not found in the .mani‐ fest files. For example, cmake -Dallow_versions=8.0.50608.0 -PCmakeVerifyManifest.cmake could be used to allow an embeded manifest of 8.0.50608.0 to be used in a project even if that version was not found in the .manifest file. CPackBundle CPack Bundle generator (Mac OS X) specific options Variables specific to CPack Bundle generator Installers built on Mac OS X using the Bundle generator use the aforementioned DragNDrop (CPACK_DMG_xxx) variables, plus the following Bundle-specific parameters (CPACK_BUN‐ DLE_xxx). CPACK_BUNDLE_NAME The name of the generated bundle. This appears in the OSX finder as the bundle name. Required. CPACK_BUNDLE_PLIST Path to an OSX plist file that will be used for the generated bundle. This assumes that the caller has generated or specified their own Info.plist file. Required. CPACK_BUNDLE_ICON Path to an OSX icon file that will be used as the icon for the generated bundle. This is the icon that appears in the OSX finder for the bundle, and in the OSX dock when the bundle is opened. Required. CPACK_BUNDLE_STARTUP_COMMAND Path to a startup script. This is a path to an executable or script that will be run whenever an end-user double-clicks the generated bundle in the OSX Finder. Optional. CPACK_BUNDLE_APPLE_CERT_APP The name of your Apple supplied code signing certificate for the application. The name usually takes the form "Developer ID Application: [Name]" or "3rd Party Mac Developer Application: [Name]". If this variable is not set the application will not be signed. CPACK_BUNDLE_APPLE_ENTITLEMENTS The name of the plist file that contains your apple entitlements for sandboxing your application. This file is required for submission to the Mac App Store. CPACK_BUNDLE_APPLE_CODESIGN_FILES A list of additional files that you wish to be signed. You do not need to list the main application folder, or the main executable. You should list any frameworks and plugins that are included in your app bundle. CPACK_BUNDLE_APPLE_CODESIGN_PARAMETER Additional parameter that will passed to codesign. Default value: "--deep -f" CPACK_COMMAND_CODESIGN Path to the codesign(1) command used to sign applications with an Apple cert. This variable can be used to override the automatically detected command (or specify its location if the auto-detection fails to find it.) CPackComponent Build binary and source package installers Variables concerning CPack Components The CPackComponent module is the module which handles the component part of CPack. See CPack module for general information about CPack. For certain kinds of binary installers (including the graphical installers on Mac OS X and Windows), CPack generates installers that allow users to select individual application components to install. The contents of each of the components are identified by the COM‐ PONENT argument of CMake's INSTALL command. These components can be annotated with user-friendly names and descriptions, inter-component dependencies, etc., and grouped in various ways to customize the resulting installer. See the cpack_add_* commands, described below, for more information about component-specific installations. Component-specific installation allows users to select specific sets of components to install during the install process. Installation components are identified by the COMPO‐ NENT argument of CMake's INSTALL commands, and should be further described by the follow‐ ing CPack commands: CPACK_COMPONENTS_ALL The list of component to install. The default value of this variable is computed by CPack and contains all components defined by the project. The user may set it to only include the specified compo‐ nents. CPACK_<GENNAME>_COMPONENT_INSTALL Enable/Disable component install for CPack generator <GENNAME>. Each CPack Generator (RPM, DEB, ARCHIVE, NSIS, DMG, etc...) has a legacy default behavior. e.g. RPM builds monolithic whereas NSIS builds component. One can change the default behavior by setting this variable to 0/1 or OFF/ON. CPACK_COMPONENTS_GROUPING Specify how components are grouped for multi-package component-aware CPack genera‐ tors. Some generators like RPM or ARCHIVE family (TGZ, ZIP, ...) generates several pack‐ ages files when asked for component packaging. They group the component differ‐ ently depending on the value of this variable: · ONE_PER_GROUP (default): creates one package file per component group · ALL_COMPONENTS_IN_ONE : creates a single package with all (requested) component · IGNORE : creates one package per component, i.e. IGNORE component group One can specify different grouping for different CPack generator by using a CPACK_PROJECT_CONFIG_FILE. CPACK_COMPONENT_<compName>_DISPLAY_NAME The name to be displayed for a component. CPACK_COMPONENT_<compName>_DESCRIPTION The description of a component. CPACK_COMPONENT_<compName>_GROUP The group of a component. CPACK_COMPONENT_<compName>_DEPENDS The dependencies (list of components) on which this component depends. CPACK_COMPONENT_<compName>_REQUIRED True is this component is required. cpack_add_component Describes a CPack installation component named by the COMPONENT argument to a CMake INSTALL command. cpack_add_component(compname [DISPLAY_NAME name] [DESCRIPTION description] [HIDDEN | REQUIRED | DISABLED ] [GROUP group] [DEPENDS comp1 comp2 ... ] [INSTALL_TYPES type1 type2 ... ] [DOWNLOADED] [ARCHIVE_FILE filename]) The cmake_add_component command describes an installation component, which the user can opt to install or remove as part of the graphical installation process. compname is the name of the component, as provided to the COMPONENT argument of one or more CMake INSTALL commands. DISPLAY_NAME is the displayed name of the component, used in graphical installers to dis‐ play the component name. This value can be any string. DESCRIPTION is an extended description of the component, used in graphical installers to give the user additional information about the component. Descriptions can span multiple lines using \n as the line separator. Typically, these descriptions should be no more than a few lines long. HIDDEN indicates that this component will be hidden in the graphical installer, so that the user cannot directly change whether it is installed or not. REQUIRED indicates that this component is required, and therefore will always be installed. It will be visible in the graphical installer, but it cannot be unselected. (Typically, required components are shown greyed out). DISABLED indicates that this component should be disabled (unselected) by default. The user is free to select this component for installation, unless it is also HIDDEN. DEPENDS lists the components on which this component depends. If this component is selected, then each of the components listed must also be selected. The dependency infor‐ mation is encoded within the installer itself, so that users cannot install inconsistent sets of components. GROUP names the component group of which this component is a part. If not provided, the component will be a standalone component, not part of any component group. Component groups are described with the cpack_add_component_group command, detailed below. INSTALL_TYPES lists the installation types of which this component is a part. When one of these installations types is selected, this component will automatically be selected. Installation types are described with the cpack_add_install_type command, detailed below. DOWNLOADED indicates that this component should be downloaded on-the-fly by the installer, rather than packaged in with the installer itself. For more information, see the cpack_configure_downloads command. ARCHIVE_FILE provides a name for the archive file created by CPack to be used for down‐ loaded components. If not supplied, CPack will create a file with some name based on CPACK_PACKAGE_FILE_NAME and the name of the component. See cpack_configure_downloads for more information. cpack_add_component_group Describes a group of related CPack installation components. cpack_add_component_group(groupname [DISPLAY_NAME name] [DESCRIPTION description] [PARENT_GROUP parent] [EXPANDED] [BOLD_TITLE]) The cpack_add_component_group describes a group of installation components, which will be placed together within the listing of options. Typically, component groups allow the user to select/deselect all of the components within a single group via a single group-level option. Use component groups to reduce the complexity of installers with many options. groupname is an arbitrary name used to identify the group in the GROUP argument of the cpack_add_component command, which is used to place a component in a group. The name of the group must not conflict with the name of any component. DISPLAY_NAME is the displayed name of the component group, used in graphical installers to display the component group name. This value can be any string. DESCRIPTION is an extended description of the component group, used in graphical install‐ ers to give the user additional information about the components within that group. Descriptions can span multiple lines using \n as the line separator. Typically, these descriptions should be no more than a few lines long. PARENT_GROUP, if supplied, names the parent group of this group. Parent groups are used to establish a hierarchy of groups, providing an arbitrary hierarchy of groups. EXPANDED indicates that, by default, the group should show up as "expanded", so that the user immediately sees all of the components within the group. Otherwise, the group will initially show up as a single entry. BOLD_TITLE indicates that the group title should appear in bold, to call the user's atten‐ tion to the group. cpack_add_install_type Add a new installation type containing a set of predefined component selections to the graphical installer. cpack_add_install_type(typename [DISPLAY_NAME name]) The cpack_add_install_type command identifies a set of preselected components that repre‐ sents a common use case for an application. For example, a "Developer" install type might include an application along with its header and library files, while an "End user" install type might just include the application's executable. Each component identifies itself with one or more install types via the INSTALL_TYPES argument to cpack_add_compo‐ nent. DISPLAY_NAME is the displayed name of the install type, which will typically show up in a drop-down box within a graphical installer. This value can be any string. cpack_configure_downloads Configure CPack to download selected components on-the-fly as part of the installation process. cpack_configure_downloads(site [UPLOAD_DIRECTORY dirname] [ALL] [ADD_REMOVE|NO_ADD_REMOVE]) The cpack_configure_downloads command configures installation-time downloads of selected components. For each downloadable component, CPack will create an archive containing the contents of that component, which should be uploaded to the given site. When the user selects that component for installation, the installer will download and extract the com‐ ponent in place. This feature is useful for creating small installers that only download the requested components, saving bandwidth. Additionally, the installers are small enough that they will be installed as part of the normal installation process, and the "Change" button in Windows Add/Remove Programs control panel will allow one to add or remove parts of the application after the original installation. On Windows, the downloaded-components functionality requires the ZipDLL plug-in for NSIS, available at: http://nsis.sourceforge.net/ZipDLL_plug-in On Mac OS X, installers that download components on-the-fly can only be built and installed on system using Mac OS X 10.5 or later. The site argument is a URL where the archives for downloadable components will reside, e.g., https://cmake.org/files/2.6.1/installer/ All of the archives produced by CPack should be uploaded to that location. UPLOAD_DIRECTORY is the local directory where CPack will create the various archives for each of the components. The contents of this directory should be uploaded to a location accessible by the URL given in the site argument. If omitted, CPack will use the direc‐ tory CPackUploads inside the CMake binary directory to store the generated archives. The ALL flag indicates that all components be downloaded. Otherwise, only those compo‐ nents explicitly marked as DOWNLOADED or that have a specified ARCHIVE_FILE will be down‐ loaded. Additionally, the ALL option implies ADD_REMOVE (unless NO_ADD_REMOVE is speci‐ fied). ADD_REMOVE indicates that CPack should install a copy of the installer that can be called from Windows' Add/Remove Programs dialog (via the "Modify" button) to change the set of installed components. NO_ADD_REMOVE turns off this behavior. This option is ignored on Mac OS X. CPackCygwin Cygwin CPack generator (Cygwin). Variables specific to CPack Cygwin generator The following variable is specific to installers build on and/or for Cygwin: CPACK_CYGWIN_PATCH_NUMBER The Cygwin patch number. FIXME: This documentation is incomplete. CPACK_CYGWIN_PATCH_FILE The Cygwin patch file. FIXME: This documentation is incomplete. CPACK_CYGWIN_BUILD_SCRIPT The Cygwin build script. FIXME: This documentation is incomplete. CPackDeb The builtin (binary) CPack Deb generator (Unix only) Variables specific to CPack Debian (DEB) generator CPackDeb may be used to create Deb package using CPack. CPackDeb is a CPack generator thus it uses the CPACK_XXX variables used by CPack : https://cmake.org/Wiki/CMake:CPackConfiguration. CPackDeb generator should work on any linux host but it will produce better deb package when Debian specific tools 'dpkg-xxx' are usable on the build system. CPackDeb has specific features which are controlled by the specifics CPACK_DEBIAN_XXX variables. CPACK_DEBIAN_<COMPONENT>_XXXX variables may be used in order to have component specific values. Note however that <COMPONENT> refers to the grouping name written in upper case. It may be either a component name or a component GROUP name. You'll find a detailed usage on the wiki: https://cmake.org/Wiki/CMake:CPackPackageGenerators#DEB_.28UNIX_only.29 . However as a handy reminder here comes the list of specific variables: CPACK_DEBIAN_PACKAGE_NAME CPACK_DEBIAN_<COMPONENT>_PACKAGE_NAME Set Package control field (variable is automatically transformed to lower case). · Mandatory : YES · Default : · CPACK_PACKAGE_NAME for non-component based installations · CPACK_DEBIAN_PACKAGE_NAME suffixed with -<COMPONENT> for component-based installations. See https://www.debian.org/doc/debian-policy/ch-controlfields.html#s-f-Source CPACK_DEBIAN_PACKAGE_VERSION The Debian package version · Mandatory : YES · Default : CPACK_PACKAGE_VERSION CPACK_DEBIAN_PACKAGE_ARCHITECTURE The Debian package architecture · Mandatory : YES · Default : Output of dpkg --print-architecture (or i386 if dpkg is not found) CPACK_DEBIAN_PACKAGE_DEPENDS CPACK_DEBIAN_<COMPONENT>_PACKAGE_DEPENDS Sets the Debian dependencies of this package. · Mandatory : NO · Default : · An empty string for non-component based installations · CPACK_DEBIAN_PACKAGE_DEPENDS for component-based installations. NOTE: If CPACK_DEBIAN_PACKAGE_SHLIBDEPS or more specifically CPACK_DEBIAN_<COMPONENT>_PACKAGE_SHLIBDEPS is set for this component, the dis‐ covered dependencies will be appended to CPACK_DEBIAN_<COMPONENT>_PACKAGE_DEPENDS instead of CPACK_DEBIAN_PACKAGE_DEPENDS. If CPACK_DEBIAN_<COMPONENT>_PACKAGE_DEPENDS is an empty string, only the automatically discovered dependencies will be set for this component. Example: set(CPACK_DEBIAN_PACKAGE_DEPENDS "libc6 (>= 2.3.1-6), libc6 (< 2.4)") CPACK_DEBIAN_PACKAGE_MAINTAINER The Debian package maintainer · Mandatory : YES · Default : CPACK_PACKAGE_CONTACT CPACK_DEBIAN_PACKAGE_DESCRIPTION CPACK_COMPONENT_<COMPONENT>_DESCRIPTION The Debian package description · Mandatory : YES · Default : · CPACK_DEBIAN_PACKAGE_DESCRIPTION if set or · CPACK_PACKAGE_DESCRIPTION_SUMMARY CPACK_DEBIAN_PACKAGE_SECTION CPACK_DEBIAN_<COMPONENT>_PACKAGE_SECTION Set Section control field e.g. admin, devel, doc, ... · Mandatory : YES · Default : 'devel' See https://www.debian.org/doc/debian-policy/ch-archive.html#s-subsections CPACK_DEBIAN_COMPRESSION_TYPE The compression used for creating the Debian package. Possible values are: lzma, xz, bzip2 and gzip. · Mandatory : YES · Default : 'gzip' CPACK_DEBIAN_PACKAGE_PRIORITY CPACK_DEBIAN_<COMPONENT>_PACKAGE_PRIORITY Set Priority control field e.g. required, important, standard, optional, extra · Mandatory : YES · Default : 'optional' See https://www.debian.org/doc/debian-policy/ch-archive.html#s-priorities CPACK_DEBIAN_PACKAGE_HOMEPAGE The URL of the web site for this package, preferably (when applicable) the site from which the original source can be obtained and any additional upstream documen‐ tation or information may be found. · Mandatory : NO · Default : - NOTE: The content of this field is a simple URL without any surrounding characters such as <>. CPACK_DEBIAN_PACKAGE_SHLIBDEPS CPACK_DEBIAN_<COMPONENT>_PACKAGE_SHLIBDEPS May be set to ON in order to use dpkg-shlibdeps to generate better package depen‐ dency list. · Mandatory : NO · Default : · CPACK_DEBIAN_PACKAGE_SHLIBDEPS if set or · OFF NOTE: You may need set CMAKE_INSTALL_RPATH to an appropriate value if you use this feature, because if you don't dpkg-shlibdeps may fail to find your own shared libs. See https://cmake.org/Wiki/CMake_RPATH_handling. CPACK_DEBIAN_PACKAGE_DEBUG May be set when invoking cpack in order to trace debug information during CPackDeb run. · Mandatory : NO · Default : - CPACK_DEBIAN_PACKAGE_PREDEPENDS CPACK_DEBIAN_<COMPONENT>_PACKAGE_PREDEPENDS Sets the Pre-Depends field of the Debian package. Like Depends, except that it also forces dpkg to complete installation of the packages named before even start‐ ing the installation of the package which declares the pre-dependency. · Mandatory : NO · Default : · An empty string for non-component based installations · CPACK_DEBIAN_PACKAGE_PREDEPENDS for component-based installations. See http://www.debian.org/doc/debian-policy/ch-relationships.html#s-binarydeps CPACK_DEBIAN_PACKAGE_ENHANCES CPACK_DEBIAN_<COMPONENT>_PACKAGE_ENHANCES Sets the Enhances field of the Debian package. Similar to Suggests but works in the opposite direction: declares that a package can enhance the functionality of another package. · Mandatory : NO · Default : · An empty string for non-component based installations · CPACK_DEBIAN_PACKAGE_ENHANCES for component-based installations. See http://www.debian.org/doc/debian-policy/ch-relationships.html#s-binarydeps CPACK_DEBIAN_PACKAGE_BREAKS CPACK_DEBIAN_<COMPONENT>_PACKAGE_BREAKS Sets the Breaks field of the Debian package. When a binary package (P) declares that it breaks other packages (B), dpkg will not allow the package (P) which declares Breaks be unpacked unless the packages that will be broken (B) are decon‐ figured first. As long as the package (P) is configured, the previously deconfig‐ ured packages (B) cannot be reconfigured again. · Mandatory : NO · Default : · An empty string for non-component based installations · CPACK_DEBIAN_PACKAGE_BREAKS for component-based installations. See https://www.debian.org/doc/debian-policy/ch-relationships.html#s-breaks CPACK_DEBIAN_PACKAGE_CONFLICTS CPACK_DEBIAN_<COMPONENT>_PACKAGE_CONFLICTS Sets the Conflicts field of the Debian package. When one binary package declares a conflict with another using a Conflicts field, dpkg will not allow them to be unpacked on the system at the same time. · Mandatory : NO · Default : · An empty string for non-component based installations · CPACK_DEBIAN_PACKAGE_CONFLICTS for component-based installations. See https://www.debian.org/doc/debian-policy/ch-relationships.html#s-conflicts NOTE: This is a stronger restriction than Breaks, which prevents the broken package from being configured while the breaking package is in the "Unpacked" state but allows both packages to be unpacked at the same time. CPACK_DEBIAN_PACKAGE_PROVIDES CPACK_DEBIAN_<COMPONENT>_PACKAGE_PROVIDES Sets the Provides field of the Debian package. A virtual package is one which appears in the Provides control field of another package. · Mandatory : NO · Default : · An empty string for non-component based installations · CPACK_DEBIAN_PACKAGE_PROVIDES for component-based installations. See https://www.debian.org/doc/debian-policy/ch-relationships.html#s-virtual CPACK_DEBIAN_PACKAGE_REPLACES CPACK_DEBIAN_<COMPONENT>_PACKAGE_REPLACES Sets the Replaces field of the Debian package. Packages can declare in their con‐ trol file that they should overwrite files in certain other packages, or completely replace other packages. · Mandatory : NO · Default : · An empty string for non-component based installations · CPACK_DEBIAN_PACKAGE_REPLACES for component-based installations. See http://www.debian.org/doc/debian-policy/ch-relationships.html#s-binarydeps CPACK_DEBIAN_PACKAGE_RECOMMENDS CPACK_DEBIAN_<COMPONENT>_PACKAGE_RECOMMENDS Sets the Recommends field of the Debian package.

See http://www.debian.org/doc/debian-policy/ch-relationships.html#s-binarydeps CPACK_DEBIAN_PACKAGE_SUGGESTS CPACK_DEBIAN_<COMPONENT>_PACKAGE_SUGGESTS Sets the Suggests field of the Debian package. Allows packages to declare a sug‐ gested package install grouping. · Mandatory : NO · Default : · An empty string for non-component based installations · CPACK_DEBIAN_PACKAGE_SUGGESTS for component-based installations. See http://www.debian.org/doc/debian-policy/ch-relationships.html#s-binarydeps CPACK_DEBIAN_PACKAGE_CONTROL_EXTRA CPACK_DEBIAN_<COMPONENT>_PACKAGE_CONTROL_EXTRA This variable allow advanced user to add custom script to the control.tar.gz. Typ‐ ical usage is for conffiles, postinst, postrm, prerm. · Mandatory : NO · Default : - Usage: set(CPACK_DEBIAN_PACKAGE_CONTROL_EXTRA "${CMAKE_CURRENT_SOURCE_DIR/prerm;${CMAKE_CURRENT_SOURCE_DIR}/postrm") NOTE: The original permissions of the files will be used in the final package unless the variable CPACK_DEBIAN_PACKAGE_CONTROL_STRICT_PERMISSION is set. In particu‐ lar, the scripts should have the proper executable flag prior to the generation of the package. CPACK_DEBIAN_PACKAGE_CONTROL_STRICT_PERMISSION CPACK_DEBIAN_<COMPONENT>_PACKAGE_CONTROL_STRICT_PERMISSION This variable indicates if the Debian policy on control files should be strictly followed. · Mandatory : NO · Default : FALSE Usage: set(CPACK_DEBIAN_PACKAGE_CONTROL_STRICT_PERMISSION TRUE) NOTE: This overrides the permissions on the original files, following the rules set by Debian policy https://www.debian.org/doc/debian-policy/ch-files.html#s-permissions-owners CPACK_DEBIAN_PACKAGE_SOURCE CPACK_DEBIAN_<COMPONENT>_PACKAGE_SOURCE Sets the Source field of the binary Debian package.

See https://www.debian.org/doc/debian-policy/ch-controlfields.html#s-f-Source NOTE: This value is not interpreted. It is possible to pass an optional revision num‐ ber of the referenced source package as well. CPackDMG DragNDrop CPack generator (Mac OS X). Variables specific to CPack DragNDrop generator The following variables are specific to the DragNDrop installers built on Mac OS X: CPACK_DMG_VOLUME_NAME The volume name of the generated disk image. Defaults to CPACK_PACKAGE_FILE_NAME. CPACK_DMG_FORMAT The disk image format. Common values are UDRO (UDIF read-only), UDZO (UDIF zlib-compressed) or UDBZ (UDIF bzip2-compressed). Refer to hdiutil(1) for more information on other available formats. CPACK_DMG_DS_STORE Path to a custom DS_Store file. This .DS_Store file e.g. can be used to specify the Finder window position/geometry and layout (such as hidden toolbars, placement of the icons etc.). This file has to be generated by the Finder (either manually or through AppleScript) using a normal folder from which the .DS_Store file can then be extracted. CPACK_DMG_DS_STORE_SETUP_SCRIPT Path to a custom AppleScript file. This AppleScript is used to generate a .DS_Store file which specifies the Finder window position/geometry and layout (such as hidden toolbars, placement of the icons etc.). By specifying a custom Apple‐ Script there is no need to use CPACK_DMG_DS_STORE, as the .DS_Store that is gener‐ ated by the AppleScript will be packaged. CPACK_DMG_BACKGROUND_IMAGE Path to an image file to be used as the background. This file will be copied to .background/background.<ext>, where ext is the original image file extension. The background image is installed into the image before CPACK_DMG_DS_STORE_SETUP_SCRIPT is executed or CPACK_DMG_DS_STORE is installed. By default no background image is set. CPACK_DMG_SLA_DIR Directory where license and menu files for different languages are stored. Setting this causes CPack to look for a <language>.menu.txt and <language>.license.txt file for every language defined in CPACK_DMG_SLA_LANGUAGES. If both this variable and CPACK_RESOURCE_FILE_LICENSE are set, CPack will only look for the menu files and use the same license file for all languages. CPACK_DMG_SLA_LANGUAGES Languages for which a license agreement is provided when mounting the generated DMG. A menu file consists of 9 lines of text. The first line is is the name of the language itself, uppercase, in English (e.g. German). The other lines are transla‐ tions of the following strings: · Agree · Disagree · Print · Save... · You agree to the terms of the License Agreement when you click the "Agree" but‐ ton. · Software License Agreement · This text cannot be saved. The disk may be full or locked, or the file may be locked. · Unable to print. Make sure you have selected a printer. For every language in this list, CPack will try to find files <language>.menu.txt and <language>.license.txt in the directory specified by the CPACK_DMG_SLA_DIR variable. CPACK_COMMAND_HDIUTIL Path to the hdiutil(1) command used to operate on disk image files on Mac OS X. This variable can be used to override the automatically detected command (or spec‐ ify its location if the auto-detection fails to find it.) CPACK_COMMAND_SETFILE Path to the SetFile(1) command used to set extended attributes on files and direc‐ tories on Mac OS X. This variable can be used to override the automatically detected command (or specify its location if the auto-detection fails to find it.) CPACK_COMMAND_REZ Path to the Rez(1) command used to compile resources on Mac OS X. This variable can be used to override the automatically detected command (or specify its location if the auto-detection fails to find it.) CPackIFW This module looks for the location of the command line utilities supplied with the Qt In‐ staller Framework (QtIFW). The module also defines several commands to control the behavior of the CPack IFW genera‐ tor. Overview CPack IFW generator helps you to create online and offline binary cross-platform install‐ ers with a graphical user interface. CPack IFW generator prepares project installation and generates configuration and meta information for QtIFW tools. The QtIFW provides a set of tools and utilities to create installers for the supported desktop Qt platforms: Linux, Microsoft Windows, and Mac OS X. You should also install QtIFW to use CPack IFW generator. If you don't use a default path for the installation, please set the used path in the variable QTIFWDIR. Variables You can use the following variables to change behavior of CPack IFW generator. Debug CPACK_IFW_VERBOSE Set to ON to enable addition debug output. By default is OFF.

CPACK_IFW_REPOGEN_EXECUTABLE The path to "repogen" command line client. This variable is cached and can be configured user if need. Commands The module defines the following commands: ---- cpack_ifw_configure_component Sets the arguments specific to the CPack IFW generator. cpack_ifw_configure_component(<compname> [COMMON] [NAME <name>] [VERSION <version>] [SCRIPT <script>] [PRIORITY <priority>] [DEPENDS <com_id> ...] [LICENSES <display_name> <file_path> ...]) This command should be called after cpack_add_component command. COMMON if set, then the component will be packaged and installed as part of a group to which it belongs. VERSION is version of component. By default used CPACK_PACKAGE_VERSION. SCRIPT is a relative or absolute path to operations script for this component. NAME is used to create domain-like identification for this component. By default used origin component name. PRIORITY is priority of the component in the tree. DEPENDS list of dependency component identifiers in QtIFW style. LICENSES pair of <display_name> and <file_path> of license text for this component. You can specify more then one license. ---- cpack_ifw_configure_component_group Sets the arguments specific to the CPack IFW generator. cpack_ifw_configure_component_group(<grpname> [VERSION <version>] [NAME <name>] [SCRIPT <script>] [PRIORITY <priority>] [LICENSES <display_name> <file_path> ...]) This command should be called after cpack_add_component_group command. VERSION is version of component group. By default used CPACK_PACKAGE_VERSION. NAME is used to create domain-like identification for this component group. By default used origin component group name. SCRIPT is a relative or absolute path to operations script for this component group. PRIORITY is priority of the component group in the tree. LICENSES pair of <display_name> and <file_path> of license text for this component group. You can specify more then one license. ---- cpack_ifw_add_repository Add QtIFW specific remote repository. cpack_ifw_add_repository(<reponame> [DISABLED] URL <url> [USERNAME <username>] [PASSWORD <password>] [DISPLAY_NAME <display_name>]) This macro will also add the <reponame> repository to a variable CPACK_IFW_REPOSITORIES_ALL DISABLED if set, then the repository will be disabled by default. URL is points to a list of available components. USERNAME is used as user on a protected repository. PASSWORD is password to use on a protected repository. DISPLAY_NAME is string to display instead of the URL. Example usage set(CPACK_PACKAGE_NAME "MyPackage") set(CPACK_PACKAGE_DESCRIPTION_SUMMARY "MyPackage Installation Example") set(CPACK_PACKAGE_VERSION "1.0.0") # Version of installer include(CPack) include(CPackIFW) cpack_add_component(myapp DISPLAY_NAME "MyApp" DESCRIPTION "My Application") cpack_ifw_configure_component(myapp VERSION "1.2.3" # Version of component SCRIPT "operations.qs") cpack_add_component(mybigplugin DISPLAY_NAME "MyBigPlugin" DESCRIPTION "My Big Downloadable Plugin" DOWNLOADED) cpack_ifw_add_repository(myrepo URL "http://example.com/ifw/repo/myapp" DISPLAY_NAME "My Application Repository") Online installer By default CPack IFW generator makes offline installer. This means that all components will be packaged into a binary file. To make a component downloaded, you must set the DOWNLOADED option in cpack_add_compo‐ nent(). Then you would use the command cpack_configure_downloads(). If you set ALL option all components will be downloaded. You also can use command cpack_ifw_add_repository() and variable CPACK_IFW_DOWNLOAD_ALL for more specific configuration. CPack IFW generator creates "repository" dir in current binary dir. You would copy content of this dir to specified site (url).

Variables specific to CPack PackageMaker generator The following variable is specific to installers built on Mac OS X using PackageMaker: CPACK_OSX_PACKAGE_VERSION The version of Mac OS X that the resulting PackageMaker archive should be compati‐ ble with. Different versions of Mac OS X support different features. For example, CPack can only build component-based installers for Mac OS X 10.4 or newer, and can only build installers that download component son-the-fly for Mac OS X 10.5 or newer. If left blank, this value will be set to the minimum version of Mac OS X that supports the requested features. Set this variable to some value (e.g., 10.4) only if you want to guarantee that your installer will work on that version of Mac OS X, and don't mind missing extra features available in the installer shipping with later versions of Mac OS X. CPackRPM The builtin (binary) CPack RPM generator (Unix only) Variables specific to CPack RPM generator CPackRPM may be used to create RPM package using CPack. CPackRPM is a CPack generator thus it uses the CPACK_XXX variables used by CPack : https://cmake.org/Wiki/CMake:CPackConfiguration However CPackRPM has specific features which are controlled by the specifics CPACK_RPM_XXX variables. CPackRPM is a component aware generator so when CPACK_RPM_COMPONENT_INSTALL is ON some more CPACK_RPM_<ComponentName>_XXXX variables may be used in order to have compo‐ nent specific values. Note however that <componentName> refers to the grouping name. This may be either a component name or a component GROUP name. Usually those vars corre‐ spond to RPM spec file entities, one may find information about spec files here http://www.rpm.org/wiki/Docs.

A relocatable RPM may be installed using: rpm --prefix or --relocate in order to install it at an alternate place see rpm(8). Note that currently this may fail if CPACK_SET_DESTDIR is set to ON. If CPACK_SET_DESTDIR is set then you will get a warning message but if there is file installed with absolute path you'll get unexpected behavior. CPACK_RPM_SPEC_INSTALL_POST · Mandatory : NO · Default : - · Deprecated: YES This way of specifying post-install script is deprecated, use CPACK_RPM_POST_INSTALL_SCRIPT_FILE.

For example launch CPack like this: cpack -D CPACK_RPM_GENERATE_USER_BINARY_SPECFILE_TEMPLATE=1 -G RPM The user may then use this file in order to hand-craft is own binary spec file which may be used with CPACK_RPM_USER_BINARY_SPECFILE. CPACK_RPM_PRE_INSTALL_SCRIPT_FILE CPACK_RPM_PRE_UNINSTALL_SCRIPT_FILE · Mandatory : NO · Default : - May be used to embed a pre (un)installation script in the spec file. The refered script file(s) will be read and directly put after the %pre or %preun section If CPACK_RPM_COMPONENT_INSTALL is set to ON the (un)install script for each component can be overridden with CPACK_RPM_<COMPONENT>_PRE_INSTALL_SCRIPT_FILE and CPACK_RPM_<COMPONENT>_PRE_UNINSTALL_SCRIPT_FILE. One may verify which scriptlet has been included with: rpm -qp --scripts package.rpm CPACK_RPM_POST_INSTALL_SCRIPT_FILE CPACK_RPM_POST_UNINSTALL_SCRIPT_FILE · Mandatory : NO · Default : - May be used to embed a post (un)installation script in the spec file.

If CPACK_RPM_COMPONENT_INSTALL is set to ON the (un)install script for each compo‐ nent can be overridden with CPACK_RPM_<COMPONENT>_POST_INSTALL_SCRIPT_FILE and CPACK_RPM_<COMPONENT>_POST_UNINSTALL_SCRIPT_FILE. One may verify which scriptlet has been included with: rpm -qp --scripts package.rpm CPACK_RPM_USER_FILELIST CPACK_RPM_<COMPONENT>_USER_FILELIST · Mandatory : NO · Default : - May be used to explicitly specify %(<directive>) file line in the spec file. Like %config(noreplace) or any other directive that be found in the %files section. Since CPackRPM is generating the list of files (and directories) the user specified files of the CPACK_RPM_<COMPONENT>_USER_FILELIST list will be removed from the gen‐ erated list. CPACK_RPM_CHANGELOG_FILE RPM changelog file. · Mandatory : NO · Default : - May be used to embed a changelog in the spec file. The refered file will be read and directly put after the %changelog section. CPACK_RPM_EXCLUDE_FROM_AUTO_FILELIST list of path to be excluded. · Mandatory : NO · Default : /etc /etc/init.d /usr /usr/share /usr/share/doc /usr/bin /usr/lib /usr/lib64 /usr/include May be used to exclude path (directories or files) from the auto-generated list of paths discovered by CPack RPM. The defaut value contains a reasonable set of values if the variable is not defined by the user. If the variable is defined by the user then CPackRPM will NOT any of the default path. If you want to add some path to the default list then you can use CPACK_RPM_EXCLUDE_FROM_AUTO_FILELIST_ADDITION variable. CPACK_RPM_EXCLUDE_FROM_AUTO_FILELIST_ADDITION additional list of path to be excluded. · Mandatory : NO · Default : - May be used to add more exclude path (directories or files) from the initial default list of excluded paths. See CPACK_RPM_EXCLUDE_FROM_AUTO_FILELIST. CPACK_RPM_RELOCATION_PATHS · Mandatory : NO · Default : - May be used to specify more than one relocation path per relocatable RPM. Variable contains a list of relocation paths that if relative are prefixed by the value of CPACK_RPM_<COMPONENT>_PACKAGE_PREFIX or by the value of CPACK_PACKAG‐ ING_INSTALL_PREFIX if the component version is not provided. Variable is not com‐ ponent based as its content can be used to set a different path prefix for e.g. binary dir and documentation dir at the same time. Only prefixes that are required by a certain component are added to that component - component must contain at least one file/directory/symbolic link with CPACK_RPM_RELOCATION_PATHS prefix for a certain relocation path to be added. Package will not contain any relocation paths if there are no files/directories/symbolic links on any of the provided prefix locations. Packages that either do not contain any relocation paths or contain files/directories/symbolic links that are outside relocation paths print out an AUTHOR_WARNING that RPM will be partially relocatable. CPACK_RPM_<COMPONENT>_PACKAGE_PREFIX · Mandatory : NO · Default : CPACK_PACKAGING_INSTALL_PREFIX May be used to set per component CPACK_PACKAGING_INSTALL_PREFIX for relocatable RPM packages. CPACK_RPM_NO_INSTALL_PREFIX_RELOCATION CPACK_RPM_NO_<COMPONENT>_INSTALL_PREFIX_RELOCATION · Mandatory : NO · Default CPACK_PACKAGING_INSTALL_PREFIX or CPACK_RPM_<COMPONENT>_PACKAGE_PREFIX are treated as one of relocation paths May be used to remove CPACK_PACKAGING_INSTALL_PREFIX and CPACK_RPM_<COMPO‐ NENT>_PACKAGE_PREFIX from relocatable RPM prefix paths. CPACK_RPM_ADDITIONAL_MAN_DIRS · Mandatory : NO · Default : - May be used to set additional man dirs that could potentially be compressed by brp-compress RPM macro. Variable content must be a list of regular expressions that point to directories containing man files or to man files directly. Note that in order to compress man pages a path must also be present in brp-compress RPM script and that brp-compress script must be added to RPM configuration by the operating system. Regular expressions that are added by default were taken from brp-compress RPM macro: · /usr/man/man.* · /usr/man/.*/man.* · /usr/info.* · /usr/share/man/man.* · /usr/share/man/.*/man.* · /usr/share/info.* · /usr/kerberos/man.* · /usr/X11R6/man/man.* · /usr/lib/perl5/man/man.* · /usr/share/doc/.*/man/man.* · /usr/lib/.*/man/man.* Packaging of Symbolic Links CPackRPM supports packaging of symbolic links: execute_process(COMMAND ${CMAKE_COMMAND} -E create_symlink <relative_path_location> <symlink_name>) install(FILES ${CMAKE_CURRENT_BINARY_DIR}/<symlink_name> DESTINATION <symlink_location> COMPONENT libraries) Symbolic links will be optimized (paths will be shortened if possible) before being added to the package or if multiple relocation paths are detected, a post install symlink relo‐ cation script will be generated. Symbolic links may point to locations that are not packaged by the same package (either a different component or even not packaged at all) but those locations will be treated as if they were a part of the package while determining if symlink should be either created or present in a post install script - depending on relocation paths. Currenty there are a few limitations though: · Only symbolic links with relative path can be packaged. · For component based packaging component interdependency is not checked when processing symbolic links. Symbolic links pointing to content of a different component are treated the same way as if pointing to location that will not be packaged. · Symbolic links pointing to a location through one or more intermediate symbolic links will not be handled differently - if the intermediate symbolic link(s) is also on a relocatable path, relocating it during package installation may cause initial symbolic link to point to an invalid location. CPack Build binary and source package installers. Variables common to all CPack generators The CPack module generates binary and source installers in a variety of formats using the cpack program. Inclusion of the CPack module adds two new targets to the resulting make‐ files, package and package_source, which build the binary and source installers, respec‐ tively. The generated binary installers contain everything installed via CMake's INSTALL command (and the deprecated INSTALL_FILES, INSTALL_PROGRAMS, and INSTALL_TARGETS com‐ mands). For certain kinds of binary installers (including the graphical installers on Mac OS X and Windows), CPack generates installers that allow users to select individual application components to install. See CPackComponent module for that. The CPACK_GENERATOR variable has different meanings in different contexts. In your CMake‐ Lists.txt file, CPACK_GENERATOR is a list of generators: when run with no other arguments, CPack will iterate over that list and produce one package for each generator. In a CPACK_PROJECT_CONFIG_FILE, though, CPACK_GENERATOR is a string naming a single generator. If you need per-cpack- generator logic to control other cpack settings, then you need a CPACK_PROJECT_CONFIG_FILE. The CMake source tree itself contains a CPACK_PROJECT_CONFIG_FILE. See the top level file CMakeCPackOptions.cmake.in for an example. If set, the CPACK_PROJECT_CONFIG_FILE is included automatically on a per-generator basis. It only need contain overrides. Here's how it works: · cpack runs · it includes CPackConfig.cmake · it iterates over the generators listed in that file's CPACK_GENERATOR list variable (unless told to use just a specific one via -G on the command line...) · foreach generator, it then · sets CPACK_GENERATOR to the one currently being iterated · includes the CPACK_PROJECT_CONFIG_FILE · produces the package for that generator This is the key: For each generator listed in CPACK_GENERATOR in CPackConfig.cmake, cpack will reset CPACK_GENERATOR internally to the one currently being used and then include the CPACK_PROJECT_CONFIG_FILE. Before including this CPack module in your CMakeLists.txt file, there are a variety of variables that can be set to customize the resulting installers. The most commonly-used variables are: CPACK_PACKAGE_NAME The name of the package (or application). If not specified, defaults to the project name. CPACK_PACKAGE_VENDOR The name of the package vendor. (e.g., "Kitware"). CPACK_PACKAGE_DIRECTORY The directory in which CPack is doing its packaging. If it is not set then this will default (internally) to the build dir. This variable may be defined in CPack config file or from the cpack command line option "-B". If set the command line option override the value found in the config file. CPACK_PACKAGE_VERSION_MAJOR Package major Version CPACK_PACKAGE_VERSION_MINOR Package minor Version CPACK_PACKAGE_VERSION_PATCH Package patch Version CPACK_PACKAGE_DESCRIPTION_FILE A text file used to describe the project. Used, for example, the introduction screen of a CPack-generated Windows installer to describe the project. CPACK_PACKAGE_DESCRIPTION_SUMMARY Short description of the project (only a few words). CPACK_PACKAGE_FILE_NAME The name of the package file to generate, not including the extension. For example, cmake-2.6.1-Linux-i686. The default value is: ${CPACK_PACKAGE_NAME}-${CPACK_PACKAGE_VERSION}-${CPACK_SYSTEM_NAME}. CPACK_PACKAGE_INSTALL_DIRECTORY Installation directory on the target system. This may be used by some CPack genera‐ tors like NSIS to create an installation directory e.g., "CMake 2.5" below the installation prefix. All installed element will be put inside this directory. CPACK_PACKAGE_ICON A branding image that will be displayed inside the installer (used by GUI install‐ ers). CPACK_PROJECT_CONFIG_FILE CPack-time project CPack configuration file. This file included at cpack time, once per generator after CPack has set CPACK_GENERATOR to the actual generator being used. It allows per-generator setting of CPACK_* variables at cpack time. CPACK_RESOURCE_FILE_LICENSE License to be embedded in the installer. It will typically be displayed to the user by the produced installer (often with an explicit "Accept" button, for graphical installers) prior to installation. This license file is NOT added to installed file but is used by some CPack generators like NSIS. If you want to install a license file (may be the same as this one) along with your project you must add an appro‐ priate CMake INSTALL command in your CMakeLists.txt. CPACK_RESOURCE_FILE_README ReadMe file to be embedded in the installer. It typically describes in some detail the purpose of the project during the installation. Not all CPack generators uses this file. CPACK_RESOURCE_FILE_WELCOME Welcome file to be embedded in the installer. It welcomes users to this installer. Typically used in the graphical installers on Windows and Mac OS X. CPACK_MONOLITHIC_INSTALL Disables the component-based installation mechanism. When set the component speci‐ fication is ignored and all installed items are put in a single "MONOLITHIC" pack‐ age. Some CPack generators do monolithic packaging by default and may be asked to do component packaging by setting CPACK_<GENNAME>_COMPONENT_INSTALL to 1/TRUE. CPACK_GENERATOR List of CPack generators to use. If not specified, CPack will create a set of options CPACK_BINARY_<GENNAME> (e.g., CPACK_BINARY_NSIS) allowing the user to enable/disable individual generators. This variable may be used on the command line as well as in: cpack -D CPACK_GENERATOR="ZIP;TGZ" /path/to/build/tree CPACK_OUTPUT_CONFIG_FILE The name of the CPack binary configuration file. This file is the CPack configura‐ tion generated by the CPack module for binary installers. Defaults to CPackCon‐ fig.cmake. CPACK_PACKAGE_EXECUTABLES Lists each of the executables and associated text label to be used to create Start Menu shortcuts. For example, setting this to the list ccmake;CMake will create a shortcut named "CMake" that will execute the installed executable ccmake. Not all CPack generators use it (at least NSIS, WIX and OSXX11 do). CPACK_STRIP_FILES List of files to be stripped. Starting with CMake 2.6.0 CPACK_STRIP_FILES will be a boolean variable which enables stripping of all files (a list of files evaluates to TRUE in CMake, so this change is compatible). CPACK_VERBATIM_VARIABLES If set to TRUE, values of variables prefixed with CPACK will be escaped before being written to the configuration files, so that the cpack program receives them exactly as they were specified. If not, characters like quotes and backslashes can cause parsing errors or alter the value received by the cpack program. Defaults to FALSE for backwards compatibility. · Mandatory : NO · Default : FALSE The following CPack variables are specific to source packages, and will not affect binary packages: CPACK_SOURCE_PACKAGE_FILE_NAME The name of the source package. For example cmake-2.6.1. CPACK_SOURCE_STRIP_FILES List of files in the source tree that will be stripped. Starting with CMake 2.6.0 CPACK_SOURCE_STRIP_FILES will be a boolean variable which enables stripping of all files (a list of files evaluates to TRUE in CMake, so this change is compatible). CPACK_SOURCE_GENERATOR List of generators used for the source packages. As with CPACK_GENERATOR, if this is not specified then CPack will create a set of options (e.g., CPACK_SOURCE_ZIP) allowing users to select which packages will be generated. CPACK_SOURCE_OUTPUT_CONFIG_FILE The name of the CPack source configuration file. This file is the CPack configura‐ tion generated by the CPack module for source installers. Defaults to CPackSource‐ Config.cmake. CPACK_SOURCE_IGNORE_FILES Pattern of files in the source tree that won't be packaged when building a source package. This is a list of regular expression patterns (that must be properly escaped), e.g., /CVS/;/\.svn/;\.swp$;\.#;/#;.*~;cscope.* The following variables are for advanced uses of CPack: CPACK_CMAKE_GENERATOR What CMake generator should be used if the project is CMake project. Defaults to the value of CMAKE_GENERATOR few users will want to change this setting. CPACK_INSTALL_CMAKE_PROJECTS List of four values that specify what project to install. The four values are: Build directory, Project Name, Project Component, Directory. If omitted, CPack will build an installer that installs everything. CPACK_SYSTEM_NAME System name, defaults to the value of ${CMAKE_SYSTEM_NAME}. CPACK_PACKAGE_VERSION Package full version, used internally. By default, this is built from CPACK_PACK‐ AGE_VERSION_MAJOR, CPACK_PACKAGE_VERSION_MINOR, and CPACK_PACKAGE_VERSION_PATCH. CPACK_TOPLEVEL_TAG Directory for the installed files. CPACK_INSTALL_COMMANDS Extra commands to install components. CPACK_INSTALLED_DIRECTORIES Extra directories to install. CPACK_PACKAGE_INSTALL_REGISTRY_KEY Registry key used when installing this project. This is only used by installer for Windows. The default value is based on the installation directory. CPACK_CREATE_DESKTOP_LINKS List of desktop links to create. Each desktop link requires a corresponding start menu shortcut as created by CPACK_PACKAGE_EXECUTABLES. CPACK_BINARY_<GENNAME> CPack generated options for binary generators. The CPack.cmake module generates (when CPACK_GENERATOR is not set) a set of CMake options (see CMake option command) which may then be used to select the CPack generator(s) to be used when launching the package target. Provide options to choose generators we might check here if the required tools for the generates exist and set the defaults according to the results CPackWIX CPack WiX generator specific options Variables specific to CPack WiX generator The following variables are specific to the installers built on Windows using WiX. CPACK_WIX_UPGRADE_GUID Upgrade GUID (Product/@UpgradeCode) Will be automatically generated unless explicitly provided. It should be explicitly set to a constant generated globally unique identifier (GUID) to allow your installers to replace existing installations that use the same GUID. You may for example explicitly set this variable in your CMakeLists.txt to the value that has been generated per default. You should not use GUIDs that you did not generate yourself or which may belong to other projects. A GUID shall have the following fixed length syntax: XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX (each X represents an uppercase hexadecimal digit) CPACK_WIX_PRODUCT_GUID Product GUID (Product/@Id) Will be automatically generated unless explicitly provided. If explicitly provided this will set the Product Id of your installer. The installer will abort if it detects a pre-existing installation that uses the same GUID. The GUID shall use the syntax described for CPACK_WIX_UPGRADE_GUID. CPACK_WIX_LICENSE_RTF RTF License File If CPACK_RESOURCE_FILE_LICENSE has an .rtf extension it is used as-is. If CPACK_RESOURCE_FILE_LICENSE has an .txt extension it is implicitly converted to RTF by the WiX Generator. The expected encoding of the .txt file is UTF-8. With CPACK_WIX_LICENSE_RTF you can override the license file used by the WiX Gener‐ ator in case CPACK_RESOURCE_FILE_LICENSE is in an unsupported format or the .txt -> .rtf conversion does not work as expected. CPACK_WIX_PRODUCT_ICON The Icon shown next to the program name in Add/Remove programs. If set, this icon is used in place of the default icon. CPACK_WIX_UI_REF This variable allows you to override the Id of the <UIRef> element in the WiX tem‐ plate. The default is WixUI_InstallDir in case no CPack components have been defined and WixUI_FeatureTree otherwise. CPACK_WIX_UI_BANNER The bitmap will appear at the top of all installer pages other than the welcome and completion dialogs. If set, this image will replace the default banner image. This image must be 493 by 58 pixels. CPACK_WIX_UI_DIALOG Background bitmap used on the welcome and completion dialogs. If this variable is set, the installer will replace the default dialog image. This image must be 493 by 312 pixels. CPACK_WIX_PROGRAM_MENU_FOLDER Start menu folder name for launcher. If this variable is not set, it will be initialized with CPACK_PACKAGE_NAME CPACK_WIX_CULTURES Language(s) of the installer Languages are compiled into the WixUI extension library. To use them, simply pro‐ vide the name of the culture. If you specify more than one culture identifier in a comma or semicolon delimited list, the first one that is found will be used. You can find a list of supported languages at: http://wix.sourceforge.net/manual-wix3/WixUI_localization.htm CPACK_WIX_TEMPLATE Template file for WiX generation If this variable is set, the specified template will be used to generate the WiX wxs file. This should be used if further customization of the output is required. If this variable is not set, the default MSI template included with CMake will be used. CPACK_WIX_PATCH_FILE Optional list of XML files with fragments to be inserted into generated WiX sources This optional variable can be used to specify an XML file that the WiX generator will use to inject fragments into its generated source files. Patch files understood by the CPack WiX generator roughly follow this RELAX NG com‐ pact schema: start = CPackWiXPatch CPackWiXPatch = element CPackWiXPatch { CPackWiXFragment* } CPackWiXFragment = element CPackWiXFragment { attribute Id { string }, fragmentContent* } fragmentContent = element * - CPackWiXFragment { (attribute * { text } | text | fragmentContent)* } Currently fragments can be injected into most Component, File and Directory ele‐ ments. The following additional special Ids can be used: · #PRODUCT for the <Product> element. · #PRODUCTFEATURE for the root <Feature> element. The following example illustrates how this works. Given that the WiX generator creates the following XML element: <Component Id="CM_CP_applications.bin.my_libapp.exe" Guid="*"/> The following XML patch file may be used to inject an Environment element into it: <CPackWiXPatch> <CPackWiXFragment Id="CM_CP_applications.bin.my_libapp.exe"> <Environment Id="MyEnvironment" Action="set" Name="MyVariableName" Value="MyVariableValue"/> </CPackWiXFragment> </CPackWiXPatch> CPACK_WIX_EXTRA_SOURCES Extra WiX source files This variable provides an optional list of extra WiX source files (.wxs) that should be compiled and linked. The full path to source files is required. CPACK_WIX_EXTRA_OBJECTS Extra WiX object files or libraries This variable provides an optional list of extra WiX object (.wixobj) and/or WiX library (.wixlib) files. The full path to objects and libraries is required. CPACK_WIX_EXTENSIONS This variable provides a list of additional extensions for the WiX tools light and candle. CPACK_WIX_<TOOL>_EXTENSIONS This is the tool specific version of CPACK_WIX_EXTENSIONS. <TOOL> can be either LIGHT or CANDLE. CPACK_WIX_<TOOL>_EXTRA_FLAGS This list variable allows you to pass additional flags to the WiX tool <TOOL>. Use it at your own risk. Future versions of CPack may generate flags which may be in conflict with your own flags. <TOOL> can be either LIGHT or CANDLE. CPACK_WIX_CMAKE_PACKAGE_REGISTRY If this variable is set the generated installer will create an entry in the windows registry key HKEY_LOCAL_MACHINE\Software\Kitware\CMake\Packages\<package> The value for <package> is provided by this variable. Assuming you also install a CMake configuration file this will allow other CMake projects to find your package with the find_package() command. CPACK_WIX_PROPERTY_<PROPERTY> This variable can be used to provide a value for the Windows Installer property <PROPERTY> The following list contains some example properties that can be used to customize information under "Programs and Features" (also known as "Add or Remove Programs") · ARPCOMMENTS - Comments · ARPHELPLINK - Help and support information URL · ARPURLINFOABOUT - General information URL · URLUPDATEINFO - Update information URL · ARPHELPTELEPHONE - Help and support telephone number · ARPSIZE - Size (in kilobytes) of the application CTest Configure a project for testing with CTest/CDash Include this module in the top CMakeLists.txt file of a project to enable testing with CTest and dashboard submissions to CDash: project(MyProject) ... include(CTest) The module automatically creates a BUILD_TESTING option that selects whether to enable testing support (ON by default). After including the module, use code like: if(BUILD_TESTING) # ... CMake code to create tests ... endif() to creating tests when testing is enabled. To enable submissions to a CDash server, create a CTestConfig.cmake file at the top of the project with content such as: set(CTEST_PROJECT_NAME "MyProject") set(CTEST_NIGHTLY_START_TIME "01:00:00 UTC") set(CTEST_DROP_METHOD "http") set(CTEST_DROP_SITE "my.cdash.org") set(CTEST_DROP_LOCATION "/submit.php?project=MyProject") set(CTEST_DROP_SITE_CDASH TRUE) (the CDash server can provide the file to a project administrator who configures MyPro‐ ject). Settings in the config file are shared by both this CTest module and the ctest(1) command-line Dashboard Client mode (ctest -S). While building a project for submission to CDash, CTest scans the build output for errors and warnings and reports them with surrounding context from the build log. This generic approach works for all build tools, but does not give details about the command invocation that produced a given problem. One may get more detailed reports by setting the CTEST_USE_LAUNCHERS variable: set(CTEST_USE_LAUNCHERS 1) in the CTestConfig.cmake file. CTestCoverageCollectGCOV This module provides the function ctest_coverage_collect_gcov. The function will run gcov on the .gcda files in a binary tree and then package all of the .gcov files into a tar file with a data.json that contains the source and build directories for CDash to use in parsing the coverage data. In addtion the Labels.json files for targets that have coverage information are also put in the tar file for CDash to asign the correct labels. This file can be sent to a CDash server for display with the ctest_submit(CDASH_UPLOAD) command. cdash_coverage_collect_gcov ctest_coverage_collect_gcov(TARBALL <tarfile> [SOURCE <source_dir>][BUILD <build_dir>] [GCOV_COMMAND <gcov_command>] [GCOV_OPTIONS <options>...] ) Run gcov and package a tar file for CDash. The options are: TARBALL <tarfile> Specify the location of the .tar file to be created for later upload to CDash. Relative paths will be interpreted with respect to the top-level build directory. SOURCE <source_dir> Specify the top-level source directory for the build. Default is the value of CTEST_SOURCE_DIRECTORY. BUILD <build_dir> Specify the top-level build directory for the build. Default is the value of CTEST_BINARY_DIRECTORY. GCOV_COMMAND <gcov_command> Specify the full path to the gcov command on the machine. Default is the value of CTEST_COVERAGE_COMMAND. GCOV_OPTIONS <options>... Specify options to be passed to gcov. The gcov command is run as gcov <options>... -o <gcov-dir> <file>.gcda. If not specified, the default option is just -b. QUIET Suppress non-error messages that otherwise would have been printed out by this function. CTestScriptMode This file is read by ctest in script mode (-S) CTestUseLaunchers Set the RULE_LAUNCH_* global properties when CTEST_USE_LAUNCHERS is on. CTestUseLaunchers is automatically included when you include(CTest). However, it is split out into its own module file so projects can use the CTEST_USE_LAUNCHERS functionality independently. To use launchers, set CTEST_USE_LAUNCHERS to ON in a ctest -S dashboard script, and then also set it in the cache of the configured project. Both cmake and ctest need to know the value of it for the launchers to work properly. CMake needs to know in order to generate proper build rules, and ctest, in order to produce the proper error and warning analysis. For convenience, you may set the ENV variable CTEST_USE_LAUNCHERS_DEFAULT in your ctest -S script, too. Then, as long as your CMakeLists uses include(CTest) or include(CTestUse‐ Launchers), it will use the value of the ENV variable to initialize a CTEST_USE_LAUNCHERS cache variable. This cache variable initialization only occurs if CTEST_USE_LAUNCHERS is not already defined. Dart Configure a project for testing with CTest or old Dart Tcl Client This file is the backwards-compatibility version of the CTest module. It supports using the old Dart 1 Tcl client for driving dashboard submissions as well as testing with CTest. This module should be included in the CMakeLists.txt file at the top of a project. Typi‐ cal usage: include(Dart) if(BUILD_TESTING) # ... testing related CMake code ... endif() The BUILD_TESTING option is created by the Dart module to determine whether testing sup‐ port should be enabled. The default is ON. DeployQt4 Functions to help assemble a standalone Qt4 executable. A collection of CMake utility functions useful for deploying Qt4 executables. The following functions are provided by this module: write_qt4_conf resolve_qt4_paths fixup_qt4_executable install_qt4_plugin_path install_qt4_plugin install_qt4_executable Requires CMake 2.6 or greater because it uses function and PARENT_SCOPE. Also depends on BundleUtilities.cmake. WRITE_QT4_CONF(<qt_conf_dir> <qt_conf_contents>) Writes a qt.conf file with the <qt_conf_contents> into <qt_conf_dir>. RESOLVE_QT4_PATHS(<paths_var> [<executable_path>]) Loop through <paths_var> list and if any don't exist resolve them relative to the <exe‐ cutable_path> (if supplied) or the CMAKE_INSTALL_PREFIX. FIXUP_QT4_EXECUTABLE(<executable> [<qtplugins> <libs> <dirs> <plugins_dir> <request_qt_conf>]) Copies Qt plugins, writes a Qt configuration file (if needed) and fixes up a Qt4 exe‐ cutable using BundleUtilities so it is standalone and can be drag-and-drop copied to another machine as long as all of the system libraries are compatible. <executable> should point to the executable to be fixed-up. <qtplugins> should contain a list of the names or paths of any Qt plugins to be installed. <libs> will be passed to BundleUtilities and should be a list of any already installed plugins, libraries or executables to also be fixed-up. <dirs> will be passed to BundleUtilities and should contain and directories to be searched to find library dependencies. <plugins_dir> allows an custom plugins directory to be used. <request_qt_conf> will force a qt.conf file to be written even if not needed. INSTALL_QT4_PLUGIN_PATH(plugin executable copy installed_plugin_path_var <plugins_dir> <component> <configurations>) Install (or copy) a resolved <plugin> to the default plugins directory (or <plugins_dir>) relative to <executable> and store the result in <installed_plugin_path_var>. If <copy> is set to TRUE then the plugins will be copied rather than installed. This is to allow this module to be used at CMake time rather than install time. If <component> is set then anything installed will use this COMPONENT. INSTALL_QT4_PLUGIN(plugin executable copy installed_plugin_path_var <plugins_dir> <component>) Install (or copy) an unresolved <plugin> to the default plugins directory (or <plug‐ ins_dir>) relative to <executable> and store the result in <installed_plugin_path_var>. See documentation of INSTALL_QT4_PLUGIN_PATH. INSTALL_QT4_EXECUTABLE(<executable> [<qtplugins> <libs> <dirs> <plugins_dir> <request_qt_conf> <component>]) Installs Qt plugins, writes a Qt configuration file (if needed) and fixes up a Qt4 exe‐ cutable using BundleUtilities so it is standalone and can be drag-and-drop copied to another machine as long as all of the system libraries are compatible. The executable will be fixed-up at install time. <component> is the COMPONENT used for bundle fixup and plugin installation. See documentation of FIXUP_QT4_BUNDLE. Documentation DocumentationVTK.cmake This file provides support for the VTK documentation framework. It relies on several tools (Doxygen, Perl, etc). ExternalData Manage data files stored outside source tree Introduction Use this module to unambiguously reference data files stored outside the source tree and fetch them at build time from arbitrary local and remote content-addressed locations. Functions provided by this module recognize arguments with the syntax DATA{<name>} as ref‐ erences to external data, replace them with full paths to local copies of those data, and create build rules to fetch and update the local copies. For example: include(ExternalData) set(ExternalData_URL_TEMPLATES "file:///local/%(algo)/%(hash)" "file:////host/share/%(algo)/%(hash)" "http://data.org/%(algo)/%(hash)") ExternalData_Add_Test(MyData NAME MyTest COMMAND MyExe DATA{MyInput.png} ) ExternalData_Add_Target(MyData) When test MyTest runs the DATA{MyInput.png} argument will be replaced by the full path to a real instance of the data file MyInput.png on disk. If the source tree contains a con‐ tent link such as MyInput.png.md5 then the MyData target creates a real MyInput.png in the build tree. Module Functions ExternalData_Expand_Arguments The ExternalData_Expand_Arguments function evaluates DATA{} references in its argu‐ ments and constructs a new list of arguments: ExternalData_Expand_Arguments( <target> # Name of data management target <outVar> # Output variable [args...] # Input arguments, DATA{} allowed ) It replaces each DATA{} reference in an argument with the full path of a real data file on disk that will exist after the <target> builds. ExternalData_Add_Test The ExternalData_Add_Test function wraps around the CMake add_test() command but supports DATA{} references in its arguments: ExternalData_Add_Test( <target> # Name of data management target ... # Arguments of add_test(), DATA{} allowed ) It passes its arguments through ExternalData_Expand_Arguments and then invokes the add_test() command using the results. ExternalData_Add_Target The ExternalData_Add_Target function creates a custom target to manage local instances of data files stored externally: ExternalData_Add_Target( <target> # Name of data management target ) It creates custom commands in the target as necessary to make data files available for each DATA{} reference previously evaluated by other functions provided by this module. Data files may be fetched from one of the URL templates specified in the ExternalData_URL_TEMPLATES variable, or may be found locally in one of the paths specified in the ExternalData_OBJECT_STORES variable. Module Variables The following variables configure behavior. They should be set before calling any of the functions provided by this module. ExternalData_BINARY_ROOT The ExternalData_BINARY_ROOT variable may be set to the directory to hold the real data files named by expanded DATA{} references. The default is CMAKE_BINARY_DIR. The directory layout will mirror that of content links under External‐ Data_SOURCE_ROOT. ExternalData_CUSTOM_SCRIPT_<key> Specify a full path to a .cmake custom fetch script identified by <key> in entries of the ExternalData_URL_TEMPLATES list. See Custom Fetch Scripts. ExternalData_LINK_CONTENT The ExternalData_LINK_CONTENT variable may be set to the name of a supported hash algorithm to enable automatic conversion of real data files referenced by the DATA{} syntax into content links. For each such <file> a content link named <file><ext> is created. The original file is renamed to the form .External‐ Data_<algo>_<hash> to stage it for future transmission to one of the locations in the list of URL templates (by means outside the scope of this module). The data fetch rule created for the content link will use the staged object if it cannot be found using any URL template. ExternalData_NO_SYMLINKS The real data files named by expanded DATA{} references may be made available under ExternalData_BINARY_ROOT using symbolic links on some platforms. The External‐ Data_NO_SYMLINKS variable may be set to disable use of symbolic links and enable use of copies instead. ExternalData_OBJECT_STORES The ExternalData_OBJECT_STORES variable may be set to a list of local directories that store objects using the layout <dir>/%(algo)/%(hash). These directories will be searched first for a needed object. If the object is not available in any store then it will be fetched remotely using the URL templates and added to the first local store listed. If no stores are specified the default is a location inside the build tree. ExternalData_SERIES_PARSE ExternalData_SERIES_PARSE_PREFIX ExternalData_SERIES_PARSE_NUMBER ExternalData_SERIES_PARSE_SUFFIX ExternalData_SERIES_MATCH See Referencing File Series. ExternalData_SOURCE_ROOT The ExternalData_SOURCE_ROOT variable may be set to the highest source directory containing any path named by a DATA{} reference. The default is CMAKE_SOURCE_DIR. ExternalData_SOURCE_ROOT and CMAKE_SOURCE_DIR must refer to directories within a single source distribution (e.g. they come together in one tarball). ExternalData_TIMEOUT_ABSOLUTE The ExternalData_TIMEOUT_ABSOLUTE variable sets the download absolute timeout, in seconds, with a default of 300 seconds. Set to 0 to disable enforcement. ExternalData_TIMEOUT_INACTIVITY The ExternalData_TIMEOUT_INACTIVITY variable sets the download inactivity timeout, in seconds, with a default of 60 seconds. Set to 0 to disable enforcement. ExternalData_URL_ALGO_<algo>_<key> Specify a custom URL component to be substituted for URL template placeholders of the form %(algo:<key>), where <key> is a valid C identifier, when fetching an object referenced via hash algorithm <algo>. If not defined, the default URL com‐ ponent is just <algo> for any <key>. ExternalData_URL_TEMPLATES The ExternalData_URL_TEMPLATES may be set to provide a list of of URL templates using the placeholders %(algo) and %(hash) in each template. Data fetch rules try each URL template in order by substituting the hash algorithm name for %(algo) and the hash value for %(hash). Alternatively one may use %(algo:<key>) with External‐ Data_URL_ALGO_<algo>_<key> variables to gain more flexibility in remote URLs. Referencing Files Referencing Single Files The DATA{} syntax is literal and the <name> is a full or relative path within the source tree. The source tree must contain either a real data file at <name> or a "content link" at <name><ext> containing a hash of the real file using a hash algorithm corresponding to <ext>. For example, the argument DATA{img.png} may be satisfied by either a real img.png file in the current source directory or a img.png.md5 file containing its MD5 sum. Referencing File Series The DATA{} syntax can be told to fetch a file series using the form DATA{<name>,:}, where the : is literal. If the source tree contains a group of files or content links named like a series then a reference to one member adds rules to fetch all of them. Although all members of a series are fetched, only the file originally named by the DATA{} argument is substituted for it. The default configuration recognizes file series names ending with #.ext, _#.ext, .#.ext, or -#.ext where # is a sequence of decimal digits and .ext is any single extension. Configure it with a regex that parses <number> and <suffix> parts from the end of <name>: ExternalData_SERIES_PARSE = regex of the form (<number>)(<suffix>)$ For more complicated cases set: ExternalData_SERIES_PARSE = regex with at least two () groups ExternalData_SERIES_PARSE_PREFIX = <prefix> regex group number, if any ExternalData_SERIES_PARSE_NUMBER = <number> regex group number ExternalData_SERIES_PARSE_SUFFIX = <suffix> regex group number Configure series number matching with a regex that matches the <number> part of series members named <prefix><number><suffix>: ExternalData_SERIES_MATCH = regex matching <number> in all series members Note that the <suffix> of a series does not include a hash-algorithm extension. Referencing Associated Files The DATA{} syntax can alternatively match files associated with the named file and con‐ tained in the same directory. Associated files may be specified by options using the syn‐ tax DATA{<name>,<opt1>,<opt2>,...}. Each option may specify one file by name or specify a regular expression to match file names using the syntax REGEX:<regex>. For example, the arguments: DATA{MyData/MyInput.mhd,MyInput.img} # File pair DATA{MyData/MyFrames00.png,REGEX:MyFrames[0-9]+\\.png} # Series will pass MyInput.mha and MyFrames00.png on the command line but ensure that the associ‐ ated files are present next to them. Referencing Directories The DATA{} syntax may reference a directory using a trailing slash and a list of associ‐ ated files. The form DATA{<name>/,<opt1>,<opt2>,...} adds rules to fetch any files in the directory that match one of the associated file options. For example, the argument DATA{MyDataDir/,REGEX:.*} will pass the full path to a MyDataDir directory on the command line and ensure that the directory contains files corresponding to every file or content link in the MyDataDir source directory. In order to match associated files in subdirecto‐ ries, specify a RECURSE: option, e.g. DATA{MyDataDir/,RECURSE:,REGEX:.*}. Hash Algorithms The following hash algorithms are supported: %(algo) <ext> Description ------- ----- ----------- MD5 .md5 Message-Digest Algorithm 5, RFC 1321 SHA1 .sha1 US Secure Hash Algorithm 1, RFC 3174 SHA224 .sha224 US Secure Hash Algorithms, RFC 4634 SHA256 .sha256 US Secure Hash Algorithms, RFC 4634 SHA384 .sha384 US Secure Hash Algorithms, RFC 4634 SHA512 .sha512 US Secure Hash Algorithms, RFC 4634 Note that the hashes are used only for unique data identification and download verifica‐ tion. Custom Fetch Scripts When a data file must be fetched from one of the URL templates specified in the External‐ Data_URL_TEMPLATES variable, it is normally downloaded using the file(DOWNLOAD) command. One may specify usage of a custom fetch script by using a URL template of the form Exter‐ nalDataCustomScript://<key>/<loc>. The <key> must be a C identifier, and the <loc> must contain the %(algo) and %(hash) placeholders. A variable corresponding to the key, Exter‐ nalData_CUSTOM_SCRIPT_<key>, must be set to the full path to a .cmake script file. The script will be included to perform the actual fetch, and provided with the following vari‐ ables: ExternalData_CUSTOM_LOCATION When a custom fetch script is loaded, this variable is set to the location part of the URL, which will contain the substituted hash algorithm name and content hash value. ExternalData_CUSTOM_FILE When a custom fetch script is loaded, this variable is set to the full path to a file in which the script must store the fetched content. The name of the file is unspecified and should not be interpreted in any way. The custom fetch script is expected to store fetched content in the file or set a vari‐ able: ExternalData_CUSTOM_ERROR When a custom fetch script fails to fetch the requested content, it must set this variable to a short one-line message describing the reason for failure. ExternalProject Create custom targets to build projects in external trees ExternalProject_Add The ExternalProject_Add function creates a custom target to drive download, update/patch, configure, build, install and test steps of an external project: ExternalProject_Add(<name> [<option>...]) General options are: DEPENDS <projects>... Targets on which the project depends PREFIX <dir> Root dir for entire project LIST_SEPARATOR <sep> Sep to be replaced by ; in cmd lines TMP_DIR <dir> Directory to store temporary files STAMP_DIR <dir> Directory to store step timestamps EXCLUDE_FROM_ALL 1 The "all" target does not depend on this Download step options are: DOWNLOAD_NAME <fname> File name to store (if not end of URL) DOWNLOAD_DIR <dir> Directory to store downloaded files DOWNLOAD_COMMAND <cmd>... Command to download source tree DOWNLOAD_NO_PROGRESS 1 Disable download progress reports CVS_REPOSITORY <cvsroot> CVSROOT of CVS repository CVS_MODULE <mod> Module to checkout from CVS repo CVS_TAG <tag> Tag to checkout from CVS repo SVN_REPOSITORY <url> URL of Subversion repo SVN_REVISION -r<rev> Revision to checkout from Subversion repo SVN_USERNAME <username> Username for Subversion checkout and update SVN_PASSWORD <password> Password for Subversion checkout and update SVN_TRUST_CERT 1 Trust the Subversion server site certificate GIT_REPOSITORY <url> URL of git repo GIT_TAG <tag> Git branch name, commit id or tag GIT_REMOTE_NAME <name> The optional name of the remote, default to origin GIT_SUBMODULES <module>... Git submodules that shall be updated, all if empty HG_REPOSITORY <url> URL of mercurial repo HG_TAG <tag> Mercurial branch name, commit id or tag URL /.../src.tgz Full path or URL of source URL_HASH ALGO=value Hash of file at URL URL_MD5 md5 Equivalent to URL_HASH MD5=md5 TLS_VERIFY <bool> Should certificate for https be checked TLS_CAINFO <file> Path to a certificate authority file TIMEOUT <seconds> Time allowed for file download operations Update/Patch step options are: UPDATE_COMMAND <cmd>... Source work-tree update command UPDATE_DISCONNECTED 1 Never update automatically from the remote repository PATCH_COMMAND <cmd>... Command to patch downloaded source Configure step options are: SOURCE_DIR <dir> Source dir to be used for build CONFIGURE_COMMAND <cmd>... Build tree configuration command CMAKE_COMMAND /.../cmake Specify alternative cmake executable CMAKE_GENERATOR <gen> Specify generator for native build CMAKE_GENERATOR_PLATFORM <platform> Generator-specific platform name CMAKE_GENERATOR_TOOLSET <toolset> Generator-specific toolset name CMAKE_ARGS <arg>... Arguments to CMake command line. These arguments are passed to CMake com‐ mand line, and can contain arguments other than cache values, see also CMake Options. Arguments in the form -Dvar:string=on are always passed to the com‐ mand line, and therefore cannot be changed by the user. Arguments may use generator expressions. CMAKE_CACHE_ARGS <arg>... Initial cache arguments, of the form -Dvar:string=on. These arguments are written in a pre-load a script that populates CMake cache, see also cmake -C. This allows to overcome command line length limits. These arguments are set() using the FORCE argument, and therefore cannot be changed by the user. Arguments may use generator expressions. CMAKE_CACHE_DEFAULT_ARGS <arg>... Initial default cache arguments, of the form -Dvar:string=on. These argu‐ ments are written in a pre-load a script that populates CMake cache, see also cmake -C. This allows to overcome command line length limits. These arguments can be used as default value that will be set if no previous value is found in the cache, and that the user can change later. Arguments may use generator expressions. Build step options are: BINARY_DIR <dir> Specify build dir location BUILD_COMMAND <cmd>... Command to drive the native build BUILD_IN_SOURCE 1 Use source dir for build dir BUILD_ALWAYS 1 No stamp file, build step always runs BUILD_BYPRODUCTS <file>... Files that will be generated by the build command but may or may not have their modification time updated by subsequent builds. Install step options are: INSTALL_DIR <dir> Installation prefix INSTALL_COMMAND <cmd>... Command to drive install after build Test step options are: TEST_BEFORE_INSTALL 1 Add test step executed before install step TEST_AFTER_INSTALL 1 Add test step executed after install step TEST_EXCLUDE_FROM_MAIN 1 Main target does not depend on the test step TEST_COMMAND <cmd>... Command to drive test Output logging options are: LOG_DOWNLOAD 1 Wrap download in script to log output LOG_UPDATE 1 Wrap update in script to log output LOG_CONFIGURE 1 Wrap configure in script to log output LOG_BUILD 1 Wrap build in script to log output LOG_TEST 1 Wrap test in script to log output LOG_INSTALL 1 Wrap install in script to log output Steps can be given direct access to the terminal if possible. With the Ninja gen‐ erator, this places the steps in the console pool. Options are: USES_TERMINAL_DOWNLOAD 1 Give download terminal access. USES_TERMINAL_UPDATE 1 Give update terminal access. USES_TERMINAL_CONFIGURE 1 Give configure terminal access. USES_TERMINAL_BUILD 1 Give build terminal access. USES_TERMINAL_TEST 1 Give test terminal access. USES_TERMINAL_INSTALL 1 Give install terminal access. Other options are: STEP_TARGETS <step-target>... Generate custom targets for these steps INDEPENDENT_STEP_TARGETS <step-target>... Generate custom targets for these steps that do not depend on other external projects even if a dependency is set The *_DIR options specify directories for the project, with default directories computed as follows. If the PREFIX option is given to ExternalProject_Add() or the EP_PREFIX directory property is set, then an external project is built and installed under the specified prefix: TMP_DIR = <prefix>/tmp STAMP_DIR = <prefix>/src/<name>-stamp DOWNLOAD_DIR = <prefix>/src SOURCE_DIR = <prefix>/src/<name> BINARY_DIR = <prefix>/src/<name>-build INSTALL_DIR = <prefix> Otherwise, if the EP_BASE directory property is set then components of an external project are stored under the specified base: TMP_DIR = <base>/tmp/<name> STAMP_DIR = <base>/Stamp/<name> DOWNLOAD_DIR = <base>/Download/<name> SOURCE_DIR = <base>/Source/<name> BINARY_DIR = <base>/Build/<name> INSTALL_DIR = <base>/Install/<name> If no PREFIX, EP_PREFIX, or EP_BASE is specified then the default is to set PREFIX to <name>-prefix. Relative paths are interpreted with respect to the build direc‐ tory corresponding to the source directory in which ExternalProject_Add is invoked. If SOURCE_DIR is explicitly set to an existing directory the project will be built from it. Otherwise a download step must be specified using one of the DOWN‐ LOAD_COMMAND, CVS_*, SVN_*, or URL options. The URL option may refer locally to a directory or source tarball, or refer to a remote tarball (e.g. http://.../src.tgz). If UPDATE_DISCONNECTED is set, the update step is not executed automatically when building the main target. The update step can still be added as a step target and called manually. This is useful if you want to allow to build the project when you are disconnected from the network (you might still need the network for the down‐ load step). This is disabled by default. The directory property EP_UPDATE_DISCON‐ NECTED can be used to change the default value for all the external projects in the current directory and its subdirectories. ExternalProject_Add_Step The ExternalProject_Add_Step function adds a custom step to an external project: ExternalProject_Add_Step(<name> <step> [<option>...]) Options are: COMMAND <cmd>... Command line invoked by this step COMMENT <text>... Text printed when step executes DEPENDEES <step>... Steps on which this step depends DEPENDERS <step>... Steps that depend on this step DEPENDS <file>... Files on which this step depends BYPRODUCTS <file>... Files that will be generated by this step but may or may not have their mod‐ ification time updated by subsequent builds. ALWAYS 1 No stamp file, step always runs EXCLUDE_FROM_MAIN 1 Main target does not depend on this step WORKING_DIRECTORY <dir> Working directory for command LOG 1 Wrap step in script to log output USES_TERMINAL 1 Give the step direct access to the terminal if possible. The command line, comment, working directory, and byproducts of every standard and custom step are processed to replace tokens <SOURCE_DIR>, <BINARY_DIR>, <INSTALL_DIR>, and <TMP_DIR> with corresponding property values. Any builtin step that specifies a <step>_COMMAND cmd... or custom step that specifies a COMMAND cmd... may specify additional command lines using the form COMMAND cmd.... At build time the commands will be executed in order and aborted if any one fails. For exam‐ ple: ... BUILD_COMMAND make COMMAND echo done ... specifies to run make and then echo done during the build step. Whether the current work‐ ing directory is preserved between commands is not defined. Behavior of shell operators like && is not defined. Arguments to <step>_COMMAND or COMMAND options may use generator expressions. ExternalProject_Get_Property The ExternalProject_Get_Property function retrieves external project target proper‐ ties: ExternalProject_Get_Property(<name> [prop1 [prop2 [...]]]) It stores property values in variables of the same name. Property names correspond to the keyword argument names of ExternalProject_Add. ExternalProject_Add_StepTargets The ExternalProject_Add_StepTargets function generates custom targets for the steps listed: ExternalProject_Add_StepTargets(<name> [NO_DEPENDS] [step1 [step2 [...]]]) If NO_DEPENDS is set, the target will not depend on the dependencies of the complete project. This is usually safe to use for the download, update, and patch steps that do not require that all the dependencies are updated and built. Using NO_DEPENDS for other of the default steps might break parallel builds, so you should avoid, it. For custom steps, you should consider whether or not the custom commands requires that the dependencies are configured, built and installed. If STEP_TARGETS or INDEPENDENT_STEP_TARGETS is set then ExternalProject_Add_StepTargets is automatically called at the end of matching calls to ExternalProject_Add_Step. Pass STEP_TARGETS or INDEPENDENT_STEP_TARGETS explicitly to individual ExternalProject_Add calls, or implicitly to all ExternalProject_Add calls by setting the directory properties EP_STEP_TARGETS and EP_INDEPENDENT_STEP_TARGETS. The INDEPENDENT version of the argument and of the property will call ExternalProject_Add_StepTargets with the NO_DEPENDS argu‐ ment. If STEP_TARGETS and INDEPENDENT_STEP_TARGETS are not set, clients may still manually call ExternalProject_Add_StepTargets after calling ExternalProject_Add or ExternalPro‐ ject_Add_Step. This functionality is provided to make it easy to drive the steps independently of each other by specifying targets on build command lines. For example, you may be submitting to a sub-project based dashboard, where you want to drive the configure portion of the build, then submit to the dashboard, followed by the build portion, followed by tests. If you invoke a custom target that depends on a step halfway through the step dependency chain, then all the previous steps will also run to ensure everything is up to date. For example, to drive configure, build and test steps independently for each ExternalPro‐ ject_Add call in your project, write the following line prior to any ExternalProject_Add calls in your CMakeLists.txt file: set_property(DIRECTORY PROPERTY EP_STEP_TARGETS configure build test) ExternalProject_Add_StepDependencies The ExternalProject_Add_StepDependencies function add some dependencies for some external project step: ExternalProject_Add_StepDependencies(<name> <step> [target1 [target2 [...]]]) This function takes care to set both target and file level dependencies, and will ensure that parallel builds will not break. It should be used instead of add_dependencies() when adding a dependency for some of the step targets generated by ExternalProject. FeatureSummary Macros for generating a summary of enabled/disabled features This module provides the macros feature_summary(), set_package_properties() and add_fea‐ ture_info(). For compatibility it also still provides set_package_info(), set_fea‐ ture_info(), print_enabled_features() and print_disabled_features(). These macros can be used to generate a summary of enabled and disabled packages and/or feature for a build tree: -- The following OPTIONAL packages have been found: LibXml2 (required version >= 2.4), XML processing lib, <http://xmlsoft.org> * Enables HTML-import in MyWordProcessor * Enables odt-export in MyWordProcessor PNG , A PNG image library. , <http://www.libpng.org/pub/png/> * Enables saving screenshots -- The following OPTIONAL packages have not been found: Lua51 , The Lua scripting language. , <http://www.lua.org> * Enables macros in MyWordProcessor Foo , Foo provides cool stuff. FEATURE_SUMMARY( [FILENAME <file>] [APPEND] [VAR <variable_name>] [INCLUDE_QUIET_PACKAGES] [FATAL_ON_MISSING_REQUIRED_PACKAGES] [DESCRIPTION "Found packages:"] WHAT (ALL | PACKAGES_FOUND | PACKAGES_NOT_FOUND | ENABLED_FEATURES | DISABLED_FEATURES) ) The FEATURE_SUMMARY() macro can be used to print information about enabled or disabled packages or features of a project. By default, only the names of the features/packages will be printed and their required version when one was specified. Use SET_PACKAGE_PROP‐ ERTIES() to add more useful information, like e.g. a download URL for the respective package or their purpose in the project. The WHAT option is the only mandatory option. Here you specify what information will be printed: ALL print everything ENABLED_FEATURES the list of all features which are enabled DISABLED_FEATURES the list of all features which are disabled PACKAGES_FOUND the list of all packages which have been found PACKAGES_NOT_FOUND the list of all packages which have not been found OPTIONAL_PACKAGES_FOUND only those packages which have been found which have the type OPTIONAL OPTIONAL_PACKAGES_NOT_FOUND only those packages which have not been found which have the type OPTIONAL RECOMMENDED_PACKAGES_FOUND only those packages which have been found which have the type RECOMMENDED RECOMMENDED_PACKAGES_NOT_FOUND only those packages which have not been found which have the type RECOMMENDED REQUIRED_PACKAGES_FOUND only those packages which have been found which have the type REQUIRED REQUIRED_PACKAGES_NOT_FOUND only those packages which have not been found which have the type REQUIRED RUNTIME_PACKAGES_FOUND only those packages which have been found which have the type RUNTIME RUNTIME_PACKAGES_NOT_FOUND only those packages which have not been found which have the type RUNTIME With the exception of the ALL value, these values can be combined in order to customize the output. For example: feature_summary(WHAT ENABLED_FEATURES DISABLED_FEATURES) If a FILENAME is given, the information is printed into this file. If APPEND is used, it is appended to this file, otherwise the file is overwritten if it already existed. If the VAR option is used, the information is "printed" into the specified variable. If FILENAME is not used, the information is printed to the terminal. Using the DESCRIPTION option a description or headline can be set which will be printed above the actual content. If INCLUDE_QUIET_PACKAGES is given, packages which have been searched with find_package(... QUIET) will also be listed. By default they are skipped. If FATAL_ON_MISS‐ ING_REQUIRED_PACKAGES is given, CMake will abort if a package which is marked as REQUIRED has not been found. Example 1, append everything to a file: feature_summary(WHAT ALL FILENAME ${CMAKE_BINARY_DIR}/all.log APPEND) Example 2, print the enabled features into the variable enabledFeaturesText, including QUIET packages: feature_summary(WHAT ENABLED_FEATURES INCLUDE_QUIET_PACKAGES DESCRIPTION "Enabled Features:" VAR enabledFeaturesText) message(STATUS "${enabledFeaturesText}") SET_PACKAGE_PROPERTIES(<name> PROPERTIES [ URL <url> ] [ DESCRIPTION <description> ] [ TYPE (RUNTIME|OPTIONAL|RECOMMENDED|REQUIRED) ] [ PURPOSE <purpose> ] ) Use this macro to set up information about the named package, which can then be displayed via FEATURE_SUMMARY(). This can be done either directly in the Find-module or in the project which uses the module after the find_package() call. The features for which information can be set are added automatically by the find_package() command. URL: this should be the homepage of the package, or something similar. Ideally this is set already directly in the Find-module. DESCRIPTION: A short description what that package is, at most one sentence. Ideally this is set already directly in the Find-module. TYPE: What type of dependency has the using project on that package. Default is OPTIONAL. In this case it is a package which can be used by the project when available at buildtime, but it also work without. RECOMMENDED is similar to OPTIONAL, i.e. the project will build if the package is not present, but the functionality of the resulting binaries will be severly limited. If a REQUIRED package is not available at buildtime, the project may not even build. This can be combined with the FATAL_ON_MISSING_REQUIRED_PACKAGES argument for feature_summary(). Last, a RUNTIME package is a package which is actually not used at all during the build, but which is required for actually running the resulting binaries. So if such a package is missing, the project can still be built, but it may not work later on. If set_package_properties() is called multiple times for the same package with dif‐ ferent TYPEs, the TYPE is only changed to higher TYPEs ( RUNTIME < OPTIONAL < RECOMMENDED < REQUIRED ), lower TYPEs are ignored. The TYPE property is project-specific, so it can‐ not be set by the Find-module, but must be set in the project. PURPOSE: This describes which features this package enables in the project, i.e. it tells the user what functionality he gets in the resulting binaries. If set_package_proper‐ ties() is called multiple times for a package, all PURPOSE properties are appended to a list of purposes of the package in the project. As the TYPE property, also the PURPOSE property is project-specific, so it cannot be set by the Find-module, but must be set in the project. Example for setting the info for a package: find_package(LibXml2) set_package_properties(LibXml2 PROPERTIES DESCRIPTION "A XML processing library." URL "http://xmlsoft.org/") set_package_properties(LibXml2 PROPERTIES TYPE RECOMMENDED PURPOSE "Enables HTML-import in MyWordProcessor") ... set_package_properties(LibXml2 PROPERTIES TYPE OPTIONAL PURPOSE "Enables odt-export in MyWordProcessor") find_package(DBUS) set_package_properties(DBUS PROPERTIES TYPE RUNTIME PURPOSE "Necessary to disable the screensaver during a presentation" ) ADD_FEATURE_INFO(<name> <enabled> <description>) Use this macro to add information about a feature with the given <name>. <enabled> con‐ tains whether this feature is enabled or not, <description> is a text describing the fea‐ ture. The information can be displayed using feature_summary() for ENABLED_FEATURES and DISABLED_FEATURES respectively. Example for setting the info for a feature: option(WITH_FOO "Help for foo" ON) add_feature_info(Foo WITH_FOO "The Foo feature provides very cool stuff.") The following macros are provided for compatibility with previous CMake versions: SET_PACKAGE_INFO(<name> <description> [<url> [<purpose>] ] ) Use this macro to set up information about the named package, which can then be displayed via FEATURE_SUMMARY(). This can be done either directly in the Find-module or in the project which uses the module after the find_package() call. The features for which information can be set are added automatically by the find_package() command. PRINT_ENABLED_FEATURES() Does the same as FEATURE_SUMMARY(WHAT ENABLED_FEATURES DESCRIPTION "Enabled features:") PRINT_DISABLED_FEATURES() Does the same as FEATURE_SUMMARY(WHAT DISABLED_FEATURES DESCRIPTION "Disabled features:") SET_FEATURE_INFO(<name> <description> [<url>] ) Does the same as SET_PACKAGE_INFO(<name> <description> <url> ) FindALSA Find alsa Find the alsa libraries (asound) This module defines the following variables: ALSA_FOUND - True if ALSA_INCLUDE_DIR & ALSA_LIBRARY are found ALSA_LIBRARIES - Set when ALSA_LIBRARY is found ALSA_INCLUDE_DIRS - Set when ALSA_INCLUDE_DIR is found ALSA_INCLUDE_DIR - where to find asoundlib.h, etc. ALSA_LIBRARY - the asound library ALSA_VERSION_STRING - the version of alsa found (since CMake 2.8.8) FindArmadillo Find Armadillo Find the Armadillo C++ library Using Armadillo: find_package(Armadillo REQUIRED) include_directories(${ARMADILLO_INCLUDE_DIRS}) add_executable(foo foo.cc) target_link_libraries(foo ${ARMADILLO_LIBRARIES}) This module sets the following variables: ARMADILLO_FOUND - set to true if the library is found ARMADILLO_INCLUDE_DIRS - list of required include directories ARMADILLO_LIBRARIES - list of libraries to be linked ARMADILLO_VERSION_MAJOR - major version number ARMADILLO_VERSION_MINOR - minor version number ARMADILLO_VERSION_PATCH - patch version number ARMADILLO_VERSION_STRING - version number as a string (ex: "1.0.4") ARMADILLO_VERSION_NAME - name of the version (ex: "Antipodean Antileech") FindASPELL Try to find ASPELL Once done this will define ASPELL_FOUND - system has ASPELL ASPELL_EXECUTABLE - the ASPELL executable ASPELL_INCLUDE_DIR - the ASPELL include directory ASPELL_LIBRARIES - The libraries needed to use ASPELL ASPELL_DEFINITIONS - Compiler switches required for using ASPELL FindAVIFile Locate AVIFILE library and include paths AVIFILE (http://avifile.sourceforge.net/)is a set of libraries for i386 machines to use various AVI codecs. Support is limited beyond Linux. Windows provides native AVI sup‐ port, and so doesn't need this library. This module defines AVIFILE_INCLUDE_DIR, where to find avifile.h , etc. AVIFILE_LIBRARIES, the libraries to link against AVIFILE_DEFINITIONS, definitions to use when compiling AVIFILE_FOUND, If false, don't try to use AVIFILE FindBISON Find bison executable and provide a macro to generate custom build rules. The module defines the following variables: BISON_EXECUTABLE path to the bison program BISON_VERSION version of bison BISON_FOUND true if the program was found The minimum required version of bison can be specified using the standard CMake syntax, e.g. find_package(BISON 2.1.3). If bison is found, the module defines the macro: BISON_TARGET(<Name> <YaccInput> <CodeOutput> [COMPILE_FLAGS <flags>] [DEFINES_FILE <file>] [VERBOSE <file>] ) which will create a custom rule to generate a parser. <YaccInput> is the path to a yacc file. <CodeOutput> is the name of the source file generated by bison. A header file is also be generated, and contains the token list. The options are: COMPILE_FLAGS <flags> Specify flags to be added to the bison command line. DEFINES_FILE <file> Specify a non-default header <file> to be generated by bison. VERBOSE <file> Tell bison to write verbose descriptions of the grammar and parser to the given <file>. The macro defines the following variables: BISON_<Name>_DEFINED true is the macro ran successfully BISON_<Name>_INPUT The input source file, an alias for <YaccInput> BISON_<Name>_OUTPUT_SOURCE The source file generated by bison BISON_<Name>_OUTPUT_HEADER The header file generated by bison BISON_<Name>_OUTPUTS The sources files generated by bison BISON_<Name>_COMPILE_FLAGS Options used in the bison command line Example usage: find_package(BISON) BISON_TARGET(MyParser parser.y ${CMAKE_CURRENT_BINARY_DIR}/parser.cpp DEFINES_FILE ${CMAKE_CURRENT_BINARY_DIR}/parser.h) add_executable(Foo main.cpp ${BISON_MyParser_OUTPUTS}) FindBLAS Find BLAS library This module finds an installed fortran library that implements the BLAS linear-algebra interface (see http://www.netlib.org/blas/). The list of libraries searched for is taken from the autoconf macro file, acx_blas.m4 (distributed at http://ac-archive.sourceforge.net/ac-archive/acx_blas.html). This module sets the following variables: BLAS_FOUND - set to true if a library implementing the BLAS interface is found BLAS_LINKER_FLAGS - uncached list of required linker flags (excluding -l and -L). BLAS_LIBRARIES - uncached list of libraries (using full path name) to link against to use BLAS BLAS95_LIBRARIES - uncached list of libraries (using full path name) to link against to use BLAS95 interface BLAS95_FOUND - set to true if a library implementing the BLAS f95 interface is found BLA_STATIC if set on this determines what kind of linkage we do (static) BLA_VENDOR if set checks only the specified vendor, if not set checks all the possibilities BLA_F95 if set on tries to find the f95 interfaces for BLAS/LAPACK ######### ## List of vendors (BLA_VENDOR) valid in this module # Goto,ATLAS PhiPACK,CXML,DXML,SunPerf,SCSL,SGIMATH,IBMESSL,Intel10_32 (intel mkl v10 32 bit),Intel10_64lp (intel mkl v10 64 bit,lp thread model, lp64 model), # Intel10_64lp_seq (intel mkl v10 64 bit,sequential code, lp64 model), # Intel( older versions of mkl 32 and 64 bit), ACML,ACML_MP,ACML_GPU,Apple, NAS, Generic C/CXX should be enabled to use Intel mkl FindBacktrace Find provider for backtrace(3). Checks if OS supports backtrace(3) via either libc or custom library. This module defines the following variables: Backtrace_HEADER The header file needed for backtrace(3). Cached. Could be forcibly set by user. Backtrace_INCLUDE_DIRS The include directories needed to use backtrace(3) header. Backtrace_LIBRARIES The libraries (linker flags) needed to use backtrace(3), if any. Backtrace_FOUND Is set if and only if backtrace(3) support detected. The following cache variables are also available to set or use: Backtrace_LIBRARY The external library providing backtrace, if any. Backtrace_INCLUDE_DIR The directory holding the backtrace(3) header. Typical usage is to generate of header file using configure_file() with the contents like the following: #cmakedefine01 Backtrace_FOUND #if Backtrace_FOUND # include <${Backtrace_HEADER}> #endif And then reference that generated header file in actual source. FindBoost Find Boost include dirs and libraries Use this module by invoking find_package with the form: find_package(Boost [version] [EXACT] # Minimum or EXACT version e.g. 1.36.0 [REQUIRED] # Fail with error if Boost is not found [COMPONENTS <libs>...] # Boost libraries by their canonical name ) # e.g. "date_time" for "libboost_date_time" This module finds headers and requested component libraries OR a CMake package configura‐ tion file provided by a "Boost CMake" build. For the latter case skip to the "Boost CMake" section below. For the former case results are reported in variables: Boost_FOUND - True if headers and requested libraries were found Boost_INCLUDE_DIRS - Boost include directories Boost_LIBRARY_DIRS - Link directories for Boost libraries Boost_LIBRARIES - Boost component libraries to be linked Boost_<C>_FOUND - True if component <C> was found (<C> is upper-case) Boost_<C>_LIBRARY - Libraries to link for component <C> (may include target_link_libraries debug/optimized keywords) Boost_VERSION - BOOST_VERSION value from boost/version.hpp Boost_LIB_VERSION - Version string appended to library filenames Boost_MAJOR_VERSION - Boost major version number (X in X.y.z) Boost_MINOR_VERSION - Boost minor version number (Y in x.Y.z) Boost_SUBMINOR_VERSION - Boost subminor version number (Z in x.y.Z) Boost_LIB_DIAGNOSTIC_DEFINITIONS (Windows) - Pass to add_definitions() to have diagnostic information about Boost's automatic linking displayed during compilation This module reads hints about search locations from variables: BOOST_ROOT - Preferred installation prefix (or BOOSTROOT) BOOST_INCLUDEDIR - Preferred include directory e.g. <prefix>/include BOOST_LIBRARYDIR - Preferred library directory e.g. <prefix>/lib Boost_NO_SYSTEM_PATHS - Set to ON to disable searching in locations not specified by these hint variables. Default is OFF. Boost_ADDITIONAL_VERSIONS - List of Boost versions not known to this module (Boost install locations may contain the version) and saves search results persistently in CMake cache entries: Boost_INCLUDE_DIR - Directory containing Boost headers Boost_LIBRARY_DIR_RELEASE - Directory containing release Boost libraries Boost_LIBRARY_DIR_DEBUG - Directory containing debug Boost libraries Boost_<C>_LIBRARY_DEBUG - Component <C> library debug variant Boost_<C>_LIBRARY_RELEASE - Component <C> library release variant The following IMPORTED targets are also defined: Boost::boost - Target for header-only dependencies (Boost include directory) Boost::<C> - Target for specific component dependency (shared or static library); <C> is lower- case Boost::diagnostic_definitions - interface target to enable diagnostic information about Boost's automatic linking during compilation (adds BOOST_LIB_DIAGNOSTIC) Boost::disable_autolinking - interface target to disable automatic linking with MSVC (adds BOOST_ALL_NO_LIB) Boost::dynamic_linking - interface target to enable dynamic linking linking with MSVC (adds BOOST_ALL_DYN_LINK) Implicit dependencies such as Boost::filesystem requiring Boost::system will be automati‐ cally detected and satisfied, even if system is not specified when using find_package and if Boost::system is not added to target_link_libraries. If using Boost::thread, then Thread::Thread will also be added automatically. It is important to note that the imported targets behave differently than variables cre‐ ated by this module: multiple calls to find_package(Boost) in the same directory or sub-directories with different options (e.g. static or shared) will not override the val‐ ues of the targets created by the first call. Users may set these hints or results as cache entries. Projects should not read these entries directly but instead use the above result variables. Note that some hint names start in upper-case "BOOST". One may specify these as environment variables if they are not specified as CMake variables or cache entries. This module first searches for the Boost header files using the above hint variables (excluding BOOST_LIBRARYDIR) and saves the result in Boost_INCLUDE_DIR. Then it searches for requested component libraries using the above hints (excluding BOOST_INCLUDEDIR and Boost_ADDITIONAL_VERSIONS), "lib" directories near Boost_INCLUDE_DIR, and the library name configuration settings below. It saves the library directories in Boost_LIBRARY_DIR_DEBUG and Boost_LIBRARY_DIR_RELEASE and individual library locations in Boost_<C>_LIBRARY_DEBUG and Boost_<C>_LIBRARY_RELEASE. When one changes settings used by previous searches in the same build tree (excluding environment variables) this module discards previous search results affected by the changes and searches again. Boost libraries come in many variants encoded in their file name. Users or projects may tell this module which variant to find by setting variables: Boost_USE_MULTITHREADED - Set to OFF to use the non-multithreaded libraries ('mt' tag). Default is ON. Boost_USE_STATIC_LIBS - Set to ON to force the use of the static libraries. Default is OFF. Boost_USE_STATIC_RUNTIME - Set to ON or OFF to specify whether to use libraries linked statically to the C++ runtime ('s' tag). Default is platform dependent. Boost_USE_DEBUG_RUNTIME - Set to ON or OFF to specify whether to use libraries linked to the MS debug C++ runtime ('g' tag). Default is ON. Boost_USE_DEBUG_PYTHON - Set to ON to use libraries compiled with a debug Python build ('y' tag). Default is OFF. Boost_USE_STLPORT - Set to ON to use libraries compiled with STLPort ('p' tag). Default is OFF. Boost_USE_STLPORT_DEPRECATED_NATIVE_IOSTREAMS - Set to ON to use libraries compiled with STLPort deprecated "native iostreams" ('n' tag). Default is OFF. Boost_COMPILER - Set to the compiler-specific library suffix (e.g. "-gcc43"). Default is auto-computed for the C++ compiler in use. Boost_THREADAPI - Suffix for "thread" component library name, such as "pthread" or "win32". Names with and without this suffix will both be tried. Boost_NAMESPACE - Alternate namespace used to build boost with e.g. if set to "myboost", will search for myboost_thread instead of boost_thread. Other variables one may set to control this module are: Boost_DEBUG - Set to ON to enable debug output from FindBoost. Please enable this before filing any bug report. Boost_DETAILED_FAILURE_MSG - Set to ON to add detailed information to the failure message even when the REQUIRED option is not given to the find_package call. Boost_REALPATH - Set to ON to resolve symlinks for discovered libraries to assist with packaging. For example, the "system" component library may be resolved to "/usr/lib/libboost_system.so.1.42.0" instead of "/usr/lib/libboost_system.so". This does not affect linking and should not be enabled unless the user needs this information. Boost_LIBRARY_DIR - Default value for Boost_LIBRARY_DIR_RELEASE and Boost_LIBRARY_DIR_DEBUG. On Visual Studio and Borland compilers Boost headers request automatic linking to corre‐ sponding libraries. This requires matching libraries to be linked explicitly or available in the link library search path. In this case setting Boost_USE_STATIC_LIBS to OFF may not achieve dynamic linking. Boost automatic linking typically requests static libraries with a few exceptions (such as Boost.Python). Use: add_definitions(${Boost_LIB_DIAGNOSTIC_DEFINITIONS}) to ask Boost to report information about automatic linking requests. Example to find Boost headers only: find_package(Boost 1.36.0) if(Boost_FOUND) include_directories(${Boost_INCLUDE_DIRS}) add_executable(foo foo.cc) endif() Example to find Boost libraries and use imported targets: find_package(Boost 1.56 REQUIRED COMPONENTS date_time filesystem iostreams) add_executable(foo foo.cc) target_link_libraries(foo Boost::date_time Boost::filesystem Boost::iostreams) Example to find Boost headers and some static libraries: set(Boost_USE_STATIC_LIBS ON) # only find static libs set(Boost_USE_MULTITHREADED ON) set(Boost_USE_STATIC_RUNTIME OFF) find_package(Boost 1.36.0 COMPONENTS date_time filesystem system ...) if(Boost_FOUND) include_directories(${Boost_INCLUDE_DIRS}) add_executable(foo foo.cc) target_link_libraries(foo ${Boost_LIBRARIES}) endif() Boost CMake If Boost was built using the boost-cmake project it provides a package configuration file for use with find_package's Config mode. This module looks for the package configuration file called BoostConfig.cmake or boost-config.cmake and stores the result in cache entry "Boost_DIR". If found, the package configuration file is loaded and this module returns with no further action. See documentation of the Boost CMake package configuration for details on what it provides. Set Boost_NO_BOOST_CMAKE to ON to disable the search for boost-cmake. FindBullet Try to find the Bullet physics engine This module defines the following variables BULLET_FOUND - Was bullet found BULLET_INCLUDE_DIRS - the Bullet include directories BULLET_LIBRARIES - Link to this, by default it includes all bullet components (Dynamics, Collision, LinearMath, & SoftBody) This module accepts the following variables BULLET_ROOT - Can be set to bullet install path or Windows build path FindBZip2 Try to find BZip2 Once done this will define BZIP2_FOUND - system has BZip2 BZIP2_INCLUDE_DIR - the BZip2 include directory BZIP2_LIBRARIES - Link these to use BZip2 BZIP2_NEED_PREFIX - this is set if the functions are prefixed with BZ2_ BZIP2_VERSION_STRING - the version of BZip2 found (since CMake 2.8.8) FindCABLE Find CABLE This module finds if CABLE is installed and determines where the include files and libraries are. This code sets the following variables: CABLE the path to the cable executable CABLE_TCL_LIBRARY the path to the Tcl wrapper library CABLE_INCLUDE_DIR the path to the include directory To build Tcl wrappers, you should add shared library and link it to ${CABLE_TCL_LIBRARY}. You should also add ${CABLE_INCLUDE_DIR} as an include directory. FindCoin3D Find Coin3D (Open Inventor) Coin3D is an implementation of the Open Inventor API. It provides data structures and algorithms for 3D visualization. This module defines the following variables COIN3D_FOUND - system has Coin3D - Open Inventor COIN3D_INCLUDE_DIRS - where the Inventor include directory can be found COIN3D_LIBRARIES - Link to this to use Coin3D FindCUDA Tools for building CUDA C files: libraries and build dependencies. This script locates the NVIDIA CUDA C tools. It should work on linux, windows, and mac and should be reasonably up to date with CUDA C releases. This script makes use of the standard find_package arguments of <VERSION>, REQUIRED and QUIET. CUDA_FOUND will report if an acceptable version of CUDA was found. The script will prompt the user to specify CUDA_TOOLKIT_ROOT_DIR if the prefix cannot be determined by the location of nvcc in the system path and REQUIRED is specified to find_package(). To use a different installed version of the toolkit set the environment variable CUDA_BIN_PATH before running cmake (e.g. CUDA_BIN_PATH=/usr/local/cuda1.0 instead of the default /usr/local/cuda) or set CUDA_TOOLKIT_ROOT_DIR after configuring. If you change the value of CUDA_TOOLKIT_ROOT_DIR, various components that depend on the path will be relocated. It might be necessary to set CUDA_TOOLKIT_ROOT_DIR manually on certain platforms, or to use a cuda runtime not installed in the default location. In newer versions of the tool‐ kit the cuda library is included with the graphics driver- be sure that the driver version matches what is needed by the cuda runtime version. The following variables affect the behavior of the macros in the script (in alphebetical order). Note that any of these flags can be changed multiple times in the same directory before calling CUDA_ADD_EXECUTABLE, CUDA_ADD_LIBRARY, CUDA_COMPILE, CUDA_COMPILE_PTX, CUDA_COMPILE_FATBIN, CUDA_COMPILE_CUBIN or CUDA_WRAP_SRCS: CUDA_64_BIT_DEVICE_CODE (Default matches host bit size) -- Set to ON to compile for 64 bit device code, OFF for 32 bit device code. Note that making this different from the host code when generating object or C files from CUDA code just won't work, because size_t gets defined by nvcc in the generated source. If you compile to PTX and then load the file yourself, you can mix bit sizes between device and host. CUDA_ATTACH_VS_BUILD_RULE_TO_CUDA_FILE (Default ON) -- Set to ON if you want the custom build rule to be attached to the source file in Visual Studio. Turn OFF if you add the same cuda file to multiple targets. This allows the user to build the target from the CUDA file; however, bad things can happen if the CUDA source file is added to multiple targets. When performing parallel builds it is possible for the custom build command to be run more than once and in parallel causing cryptic build errors. VS runs the rules for every source file in the target, and a source can have only one rule no matter how many projects it is added to. When the rule is run from multiple targets race conditions can occur on the generated file. Eventually everything will get built, but if the user is unaware of this behavior, there may be confusion. It would be nice if this script could detect the reuse of source files across multiple targets and turn the option off for the user, but no good solution could be found. CUDA_BUILD_CUBIN (Default OFF) -- Set to ON to enable and extra compilation pass with the -cubin option in Device mode. The output is parsed and register, shared memory usage is printed during build. CUDA_BUILD_EMULATION (Default OFF for device mode) -- Set to ON for Emulation mode. -D_DEVICEEMU is defined for CUDA C files when CUDA_BUILD_EMULATION is TRUE. CUDA_GENERATED_OUTPUT_DIR (Default CMAKE_CURRENT_BINARY_DIR) -- Set to the path you wish to have the generated files placed. If it is blank output files will be placed in CMAKE_CURRENT_BINARY_DIR. Intermediate files will always be placed in CMAKE_CURRENT_BINARY_DIR/CMakeFiles. CUDA_HOST_COMPILATION_CPP (Default ON) -- Set to OFF for C compilation of host code. CUDA_HOST_COMPILER (Default CMAKE_C_COMPILER, $(VCInstallDir)/bin for VS) -- Set the host compiler to be used by nvcc. Ignored if -ccbin or --compiler-bindir is already present in the CUDA_NVCC_FLAGS or CUDA_NVCC_FLAGS_<CONFIG> variables. For Visual Studio targets $(VCInstallDir)/bin is a special value that expands out to the path when the command is run from withing VS. CUDA_NVCC_FLAGS CUDA_NVCC_FLAGS_<CONFIG> -- Additional NVCC command line arguments. NOTE: multiple arguments must be semi-colon delimited (e.g. --compiler-options;-Wall) CUDA_PROPAGATE_HOST_FLAGS (Default ON) -- Set to ON to propagate CMAKE_{C,CXX}_FLAGS and their configuration dependent counterparts (e.g. CMAKE_C_FLAGS_DEBUG) automatically to the host compiler through nvcc's -Xcompiler flag. This helps make the generated host code match the rest of the system better. Sometimes certain flags give nvcc problems, and this will help you turn the flag propagation off. This does not affect the flags supplied directly to nvcc via CUDA_NVCC_FLAGS or through the OPTION flags specified through CUDA_ADD_LIBRARY, CUDA_ADD_EXECUTABLE, or CUDA_WRAP_SRCS. Flags used for shared library compilation are not affected by this flag. CUDA_SEPARABLE_COMPILATION (Default OFF) -- If set this will enable separable compilation for all CUDA runtime object files. If used outside of CUDA_ADD_EXECUTABLE and CUDA_ADD_LIBRARY (e.g. calling CUDA_WRAP_SRCS directly), CUDA_COMPUTE_SEPARABLE_COMPILATION_OBJECT_FILE_NAME and CUDA_LINK_SEPARABLE_COMPILATION_OBJECTS should be called. CUDA_SOURCE_PROPERTY_FORMAT -- If this source file property is set, it can override the format specified to CUDA_WRAP_SRCS (OBJ, PTX, CUBIN, or FATBIN). If an input source file is not a .cu file, setting this file will cause it to be treated as a .cu file. See documentation for set_source_files_properties on how to set this property. CUDA_USE_STATIC_CUDA_RUNTIME (Default ON) -- When enabled the static version of the CUDA runtime library will be used in CUDA_LIBRARIES. If the version of CUDA configured doesn't support this option, then it will be silently disabled. CUDA_VERBOSE_BUILD (Default OFF) -- Set to ON to see all the commands used when building the CUDA file. When using a Makefile generator the value defaults to VERBOSE (run make VERBOSE=1 to see output), although setting CUDA_VERBOSE_BUILD to ON will always print the output. The script creates the following macros (in alphebetical order): CUDA_ADD_CUFFT_TO_TARGET( cuda_target ) -- Adds the cufft library to the target (can be any target). Handles whether you are in emulation mode or not. CUDA_ADD_CUBLAS_TO_TARGET( cuda_target ) -- Adds the cublas library to the target (can be any target). Handles whether you are in emulation mode or not. CUDA_ADD_EXECUTABLE( cuda_target file0 file1 ... [WIN32] [MACOSX_BUNDLE] [EXCLUDE_FROM_ALL] [OPTIONS ...] ) -- Creates an executable "cuda_target" which is made up of the files specified. All of the non CUDA C files are compiled using the standard build rules specified by CMAKE and the cuda files are compiled to object files using nvcc and the host compiler. In addition CUDA_INCLUDE_DIRS is added automatically to include_directories(). Some standard CMake target calls can be used on the target after calling this macro (e.g. set_target_properties and target_link_libraries), but setting properties that adjust compilation flags will not affect code compiled by nvcc. Such flags should be modified before calling CUDA_ADD_EXECUTABLE, CUDA_ADD_LIBRARY or CUDA_WRAP_SRCS. CUDA_ADD_LIBRARY( cuda_target file0 file1 ... [STATIC | SHARED | MODULE] [EXCLUDE_FROM_ALL] [OPTIONS ...] ) -- Same as CUDA_ADD_EXECUTABLE except that a library is created. CUDA_BUILD_CLEAN_TARGET() -- Creates a convience target that deletes all the dependency files generated. You should make clean after running this target to ensure the dependency files get regenerated. CUDA_COMPILE( generated_files file0 file1 ... [STATIC | SHARED | MODULE] [OPTIONS ...] ) -- Returns a list of generated files from the input source files to be used with ADD_LIBRARY or ADD_EXECUTABLE. CUDA_COMPILE_PTX( generated_files file0 file1 ... [OPTIONS ...] ) -- Returns a list of PTX files generated from the input source files. CUDA_COMPILE_FATBIN( generated_files file0 file1 ... [OPTIONS ...] ) -- Returns a list of FATBIN files generated from the input source files. CUDA_COMPILE_CUBIN( generated_files file0 file1 ... [OPTIONS ...] ) -- Returns a list of CUBIN files generated from the input source files. CUDA_COMPUTE_SEPARABLE_COMPILATION_OBJECT_FILE_NAME( output_file_var cuda_target object_files ) -- Compute the name of the intermediate link file used for separable compilation. This file name is typically passed into CUDA_LINK_SEPARABLE_COMPILATION_OBJECTS. output_file_var is produced based on cuda_target the list of objects files that need separable compilation as specified by object_files. If the object_files list is empty, then output_file_var will be empty. This function is called automatically for CUDA_ADD_LIBRARY and CUDA_ADD_EXECUTABLE. Note that this is a function and not a macro. CUDA_INCLUDE_DIRECTORIES( path0 path1 ... ) -- Sets the directories that should be passed to nvcc (e.g. nvcc -Ipath0 -Ipath1 ... ). These paths usually contain other .cu files. CUDA_LINK_SEPARABLE_COMPILATION_OBJECTS( output_file_var cuda_target nvcc_flags object_files) -- Generates the link object required by separable compilation from the given object files. This is called automatically for CUDA_ADD_EXECUTABLE and CUDA_ADD_LIBRARY, but can be called manually when using CUDA_WRAP_SRCS directly. When called from CUDA_ADD_LIBRARY or CUDA_ADD_EXECUTABLE the nvcc_flags passed in are the same as the flags passed in via the OPTIONS argument. The only nvcc flag added automatically is the bitness flag as specified by CUDA_64_BIT_DEVICE_CODE. Note that this is a function instead of a macro. CUDA_WRAP_SRCS ( cuda_target format generated_files file0 file1 ... [STATIC | SHARED | MODULE] [OPTIONS ...] ) -- This is where all the magic happens. CUDA_ADD_EXECUTABLE, CUDA_ADD_LIBRARY, CUDA_COMPILE, and CUDA_COMPILE_PTX all call this function under the hood. Given the list of files (file0 file1 ... fileN) this macro generates custom commands that generate either PTX or linkable objects (use "PTX" or "OBJ" for the format argument to switch). Files that don't end with .cu or have the HEADER_FILE_ONLY property are ignored. The arguments passed in after OPTIONS are extra command line options to give to nvcc. You can also specify per configuration options by specifying the name of the configuration followed by the options. General options must preceed configuration specific options. Not all configurations need to be specified, only the ones provided will be used. OPTIONS -DFLAG=2 "-DFLAG_OTHER=space in flag" DEBUG -g RELEASE --use_fast_math RELWITHDEBINFO --use_fast_math;-g MINSIZEREL --use_fast_math For certain configurations (namely VS generating object files with CUDA_ATTACH_VS_BUILD_RULE_TO_CUDA_FILE set to ON), no generated file will be produced for the given cuda file. This is because when you add the cuda file to Visual Studio it knows that this file produces an object file and will link in the resulting object file automatically. This script will also generate a separate cmake script that is used at build time to invoke nvcc. This is for several reasons. 1. nvcc can return negative numbers as return values which confuses Visual Studio into thinking that the command succeeded. The script now checks the error codes and produces errors when there was a problem. 2. nvcc has been known to not delete incomplete results when it encounters problems. This confuses build systems into thinking the target was generated when in fact an unusable file exists. The script now deletes the output files if there was an error. 3. By putting all the options that affect the build into a file and then make the build rule dependent on the file, the output files will be regenerated when the options change. This script also looks at optional arguments STATIC, SHARED, or MODULE to determine when to target the object compilation for a shared library. BUILD_SHARED_LIBS is ignored in CUDA_WRAP_SRCS, but it is respected in CUDA_ADD_LIBRARY. On some systems special flags are added for building objects intended for shared libraries. A preprocessor macro, <target_name>_EXPORTS is defined when a shared library compilation is detected. Flags passed into add_definitions with -D or /D are passed along to nvcc. The script defines the following variables: CUDA_VERSION_MAJOR -- The major version of cuda as reported by nvcc. CUDA_VERSION_MINOR -- The minor version. CUDA_VERSION CUDA_VERSION_STRING -- CUDA_VERSION_MAJOR.CUDA_VERSION_MINOR CUDA_TOOLKIT_ROOT_DIR -- Path to the CUDA Toolkit (defined if not set). CUDA_SDK_ROOT_DIR -- Path to the CUDA SDK. Use this to find files in the SDK. This script will not directly support finding specific libraries or headers, as that isn't supported by NVIDIA. If you want to change libraries when the path changes see the FindCUDA.cmake script for an example of how to clear these variables. There are also examples of how to use the CUDA_SDK_ROOT_DIR to locate headers or libraries, if you so choose (at your own risk). CUDA_INCLUDE_DIRS -- Include directory for cuda headers. Added automatically for CUDA_ADD_EXECUTABLE and CUDA_ADD_LIBRARY. CUDA_LIBRARIES -- Cuda RT library. CUDA_CUFFT_LIBRARIES -- Device or emulation library for the Cuda FFT implementation (alternative to: CUDA_ADD_CUFFT_TO_TARGET macro) CUDA_CUBLAS_LIBRARIES -- Device or emulation library for the Cuda BLAS implementation (alterative to: CUDA_ADD_CUBLAS_TO_TARGET macro). CUDA_cudart_static_LIBRARY -- Statically linkable cuda runtime library. Only available for CUDA version 5.5+ CUDA_cupti_LIBRARY -- CUDA Profiling Tools Interface library.

Only available for CUDA version 3.2+. Windows only. FindCups Try to find the Cups printing system Once done this will define CUPS_FOUND - system has Cups CUPS_INCLUDE_DIR - the Cups include directory CUPS_LIBRARIES - Libraries needed to use Cups CUPS_VERSION_STRING - version of Cups found (since CMake 2.8.8) Set CUPS_REQUIRE_IPP_DELETE_ATTRIBUTE to TRUE if you need a version which features this function (i.e. at least 1.1.19) FindCURL Find curl Find the native CURL headers and libraries. CURL_INCLUDE_DIRS - where to find curl/curl.h, etc. CURL_LIBRARIES - List of libraries when using curl. CURL_FOUND - True if curl found. CURL_VERSION_STRING - the version of curl found (since CMake 2.8.8) FindCurses Find the curses or ncurses include file and library. Result Variables This module defines the following variables: CURSES_FOUND True if Curses is found. CURSES_INCLUDE_DIRS The include directories needed to use Curses. CURSES_LIBRARIES The libraries needed to use Curses. CURSES_HAVE_CURSES_H True if curses.h is available. CURSES_HAVE_NCURSES_H True if ncurses.h is available. CURSES_HAVE_NCURSES_NCURSES_H True if ncurses/ncurses.h is available. CURSES_HAVE_NCURSES_CURSES_H True if ncurses/curses.h is available. Set CURSES_NEED_NCURSES to TRUE before the find_package(Curses) call if NCurses function‐ ality is required. Backward Compatibility The following variable are provided for backward compatibility: CURSES_INCLUDE_DIR Path to Curses include. Use CURSES_INCLUDE_DIRS instead. CURSES_LIBRARY Path to Curses library. Use CURSES_LIBRARIES instead. FindCVS The module defines the following variables: CVS_EXECUTABLE - path to cvs command line client CVS_FOUND - true if the command line client was found Example usage: find_package(CVS) if(CVS_FOUND) message("CVS found: ${CVS_EXECUTABLE}") endif() FindCxxTest Find CxxTest Find the CxxTest suite and declare a helper macro for creating unit tests and integrating them with CTest. For more details on CxxTest see http://cxxtest.tigris.org INPUT Variables CXXTEST_USE_PYTHON [deprecated since 1.3] Only used in the case both Python & Perl are detected on the system to control which CxxTest code generator is used. Valid only for CxxTest version 3. NOTE: In older versions of this Find Module, this variable controlled if the Python test generator was used instead of the Perl one, regardless of which scripting language the user had installed. CXXTEST_TESTGEN_ARGS (since CMake 2.8.3) Specify a list of options to pass to the CxxTest code generator. If not defined, --error-printer is passed. OUTPUT Variables CXXTEST_FOUND True if the CxxTest framework was found CXXTEST_INCLUDE_DIRS Where to find the CxxTest include directory CXXTEST_PERL_TESTGEN_EXECUTABLE The perl-based test generator CXXTEST_PYTHON_TESTGEN_EXECUTABLE The python-based test generator CXXTEST_TESTGEN_EXECUTABLE (since CMake 2.8.3) The test generator that is actually used (chosen using user preferences and interpreters found in the system) CXXTEST_TESTGEN_INTERPRETER (since CMake 2.8.3) The full path to the Perl or Python executable on the system MACROS for optional use by CMake users: CXXTEST_ADD_TEST(<test_name> <gen_source_file> <input_files_to_testgen...>) Creates a CxxTest runner and adds it to the CTest testing suite Parameters: test_name The name of the test gen_source_file The generated source filename to be generated by CxxTest input_files_to_testgen The list of header files containing the CxxTest::TestSuite's to be included in this runner #============== Example Usage: find_package(CxxTest) if(CXXTEST_FOUND) include_directories(${CXXTEST_INCLUDE_DIR}) enable_testing() CXXTEST_ADD_TEST(unittest_foo foo_test.cc ${CMAKE_CURRENT_SOURCE_DIR}/foo_test.h) target_link_libraries(unittest_foo foo) # as needed endif() This will (if CxxTest is found): 1. Invoke the testgen executable to autogenerate foo_test.cc in the binary tree from "foo_test.h" in the current source directory. 2. Create an executable and test called unittest_foo. #============= Example foo_test.h: #include <cxxtest/TestSuite.h> class MyTestSuite : public CxxTest::TestSuite { public: void testAddition( void ) { TS_ASSERT( 1 + 1 > 1 ); TS_ASSERT_EQUALS( 1 + 1, 2 ); } }; FindCygwin this module looks for Cygwin FindDart Find DART This module looks for the dart testing software and sets DART_ROOT to point to where it found it. FindDCMTK Find DCMTK libraries and applications The module defines the following variables: DCMTK_INCLUDE_DIRS - Directories to include to use DCMTK DCMTK_LIBRARIES - Files to link against to use DCMTK DCMTK_FOUND - If false, don't try to use DCMTK DCMTK_DIR - (optional) Source directory for DCMTK Compatibility This module is able to find a version of DCMTK that does or does not export a DCMTKCon‐ fig.cmake file. It applies a two step process: · Step 1: Attempt to find DCMTK version providing a DCMTKConfig.cmake file. · Step 2: If step 1 failed, rely on FindDCMTK.cmake to set DCMTK_* variables details below. Recent DCMTK provides a DCMTKConfig.cmake package configuration file. To exclusively use the package configuration file (recommended when possible), pass the NO_MODULE option to find_package(). For example, find_package(DCMTK NO_MODULE). This requires official DCMTK snapshot 3.6.1_20140617 or newer. Until all clients update to the more recent DCMTK, build systems will need to support dif‐ ferent versions of DCMTK. On any given system, the following combinations of DCMTK versions could be considered: ┌───────┬─────────────────┬─────────────────┬─────────────┐ │ │ SYSTEM DCMTK │ LOCAL DCMTK │ Supported ? │ ├───────┼─────────────────┼─────────────────┼─────────────┤ │Case A │ NA │ [ ] DCMTKConfig │ YES │ ├───────┼─────────────────┼─────────────────┼─────────────┤ │Case B │ NA │ [X] DCMTKConfig │ YES │ ├───────┼─────────────────┼─────────────────┼─────────────┤ │Case C │ [ ] DCMTKConfig │ NA │ YES │ ├───────┼─────────────────┼─────────────────┼─────────────┤ │Case D │ [X] DCMTKConfig │ NA │ YES │ ├───────┼─────────────────┼─────────────────┼─────────────┤ │Case E │ [ ] DCMTKConfig │ [ ] DCMTKConfig │ YES (*) │ ├───────┼─────────────────┼─────────────────┼─────────────┤ │Case F │ [X] DCMTKConfig │ [ ] DCMTKConfig │ NO │ ├───────┼─────────────────┼─────────────────┼─────────────┤ │Case G │ [ ] DCMTKConfig │ [X] DCMTKConfig │ YES │ ├───────┼─────────────────┼─────────────────┼─────────────┤ │Case H │ [X] DCMTKConfig │ [X] DCMTKConfig │ YES │ └───────┴─────────────────┴─────────────────┴─────────────┘ (*) See Troubleshooting section. Legend: NA ...............: Means that no System or Local DCMTK is available [ ] DCMTKConfig ..: Means that the version of DCMTK does NOT export a DCMTKConfig.cmake file. [X] DCMTKConfig ..: Means that the version of DCMTK exports a DCMTKConfig.cmake file. Troubleshooting What to do if my project finds a different version of DCMTK? Remove DCMTK entry from the CMake cache per find_package() documentation. FindDevIL This module locates the developer's image library. http://openil.sourceforge.net/ This module sets: IL_LIBRARIES - the name of the IL library. These include the full path to the core DevIL library. This one has to be linked into the application. ILU_LIBRARIES - the name of the ILU library. Again, the full path. This library is for filters and effects, not actual loading. It doesn't have to be linked if the functionality it provides is not used. ILUT_LIBRARIES - the name of the ILUT library. Full path. This part of the library interfaces with OpenGL. It is not strictly needed in applications. IL_INCLUDE_DIR - where to find the il.h, ilu.h and ilut.h files. IL_FOUND - this is set to TRUE if all the above variables were set. This will be set to false if ILU or ILUT are not found, even if they are not needed. In most systems, if one library is found all the others are as well. That's the way the DevIL developers release it. FindDoxygen This module looks for Doxygen and the path to Graphviz's dot Doxygen is a documentation generation tool. Please see http://www.doxygen.org This module accepts the following optional variables: DOXYGEN_SKIP_DOT = If true this module will skip trying to find Dot (an optional component often used by Doxygen) This modules defines the following variables: DOXYGEN_EXECUTABLE = The path to the doxygen command. DOXYGEN_FOUND = Was Doxygen found or not? DOXYGEN_VERSION = The version reported by doxygen --version DOXYGEN_DOT_EXECUTABLE = The path to the dot program used by doxygen. DOXYGEN_DOT_FOUND = Was Dot found or not? For compatibility with older versions of CMake, the now-deprecated variable DOXY‐ GEN_DOT_PATH is set to the path to the directory containing dot as reported in DOXY‐ GEN_DOT_EXECUTABLE. The path may have forward slashes even on Windows and is not suitable for direct substitution into a Doxyfile.in template. If you need this value, use get_filename_component() to compute it from DOXYGEN_DOT_EXECUTABLE directly, and perhaps the file(TO_NATIVE_PATH) command to prepare the path for a Doxygen configuration file. FindEXPAT Find expat Find the native EXPAT headers and libraries. EXPAT_INCLUDE_DIRS - where to find expat.h, etc. EXPAT_LIBRARIES - List of libraries when using expat. EXPAT_FOUND - True if expat found. FindFLEX Find flex executable and provides a macro to generate custom build rules The module defines the following variables: FLEX_FOUND - true is flex executable is found FLEX_EXECUTABLE - the path to the flex executable FLEX_VERSION - the version of flex FLEX_LIBRARIES - The flex libraries FLEX_INCLUDE_DIRS - The path to the flex headers The minimum required version of flex can be specified using the standard syntax, e.g. find_package(FLEX 2.5.13) If flex is found on the system, the module provides the macro: FLEX_TARGET(Name FlexInput FlexOutput [COMPILE_FLAGS <string>] [DEFINES_FILE <string>] ) which creates a custom command to generate the <FlexOutput> file from the <FlexInput> file. If COMPILE_FLAGS option is specified, the next parameter is added to the flex com‐ mand line. If flex is configured to output a header file, the DEFINES_FILE option may be used to specify its name. Name is an alias used to get details of this custom command. Indeed the macro defines the following variables: FLEX_${Name}_DEFINED - true is the macro ran successfully FLEX_${Name}_OUTPUTS - the source file generated by the custom rule, an alias for FlexOutput FLEX_${Name}_INPUT - the flex source file, an alias for ${FlexInput} FLEX_${Name}_OUTPUT_HEADER - the header flex output, if any. Flex scanners oftenly use tokens defined by Bison: the code generated by Flex depends of the header generated by Bison. This module also defines a macro: ADD_FLEX_BISON_DEPENDENCY(FlexTarget BisonTarget) which adds the required dependency between a scanner and a parser where <FlexTarget> and <BisonTarget> are the first parameters of respectively FLEX_TARGET and BISON_TARGET macros. ==================================================================== Example: find_package(BISON) find_package(FLEX) BISON_TARGET(MyParser parser.y ${CMAKE_CURRENT_BINARY_DIR}/parser.cpp) FLEX_TARGET(MyScanner lexer.l ${CMAKE_CURRENT_BINARY_DIR}/lexer.cpp) ADD_FLEX_BISON_DEPENDENCY(MyScanner MyParser) include_directories(${CMAKE_CURRENT_BINARY_DIR}) add_executable(Foo Foo.cc ${BISON_MyParser_OUTPUTS} ${FLEX_MyScanner_OUTPUTS} ) ==================================================================== FindFLTK2 Find the native FLTK2 includes and library The following settings are defined FLTK2_FLUID_EXECUTABLE, where to find the Fluid tool FLTK2_WRAP_UI, This enables the FLTK2_WRAP_UI command FLTK2_INCLUDE_DIR, where to find include files FLTK2_LIBRARIES, list of fltk2 libraries FLTK2_FOUND, Don't use FLTK2 if false.

GETTEXT_FOUND: True if gettext has been found. GETTEXT_VERSION_STRING: the version of gettext found (since CMake 2.8.8) Additionally it provides the following macros: GETTEXT_CREATE_TRANSLATIONS ( outputFile [ALL] file1 ... fileN ) This will create a target "translations" which will convert the given input po files into the binary output mo file. If the ALL option is used, the translations will also be created when building the default target. GETTEXT_PROCESS_POT_FILE( <potfile> [ALL] [INSTALL_DESTINATION <destdir>] LANGUAGES <lang1> <lang2> ... ) Process the given pot file to mo files. If INSTALL_DESTINATION is given then automatically install rules will be created, the language subdirectory will be taken into account (by default use share/locale/). If ALL is specified, the pot file is processed when building the all traget. It creates a custom target "potfile". GETTEXT_PROCESS_PO_FILES( <lang> [ALL] [INSTALL_DESTINATION <dir>] PO_FILES <po1> <po2> ... ) Process the given po files to mo files for the given language. If INSTALL_DESTINATION is given then automatically install rules will be created, the language subdirectory will be taken into account (by default use share/locale/). If ALL is specified, the po files are processed when building the all traget. It creates a custom target "pofiles". NOTE: If you wish to use the Gettext library (libintl), use FindIntl. FindGIF This module searches giflib and defines GIF_LIBRARIES - libraries to link to in order to use GIF GIF_FOUND, if false, do not try to link GIF_INCLUDE_DIR, where to find the headers GIF_VERSION, reports either version 4 or 3 (for everything before version 4) The minimum required version of giflib can be specified using the standard syntax, e.g. find_package(GIF 4) $GIF_DIR is an environment variable that would correspond to the FindGit The module defines the following variables: GIT_EXECUTABLE Path to Git command-line client.

The GNU Scientific Library (GSL) is a numerical library for C and C++ programmers. It is free software under the GNU General Public License. Imported Targets If GSL is found, this module defines the following IMPORTED targets: GSL::gsl - The main GSL library. GSL::gslcblas - The CBLAS support library used by GSL. Result Variables This module will set the following variables in your project: GSL_FOUND - True if GSL found on the local system GSL_INCLUDE_DIRS - Location of GSL header files. GSL_LIBRARIES - The GSL libraries. GSL_VERSION - The version of the discovered GSL install. Hints Set GSL_ROOT_DIR to a directory that contains a GSL installation. This script expects to find libraries at $GSL_ROOT_DIR/lib and the GSL headers at $GSL_ROOT_DIR/include/gsl. The library directory may optionally provide Release and Debug folders. For Unix-like systems, this script will use $GSL_ROOT_DIR/bin/gsl-config (if found) to aid in the discovery GSL. Cache Variables This module may set the following variables depending on platform and type of GSL instal‐ lation discovered. These variables may optionally be set to help this module find the correct files: GSL_CLBAS_LIBRARY - Location of the GSL CBLAS library. GSL_CBLAS_LIBRARY_DEBUG - Location of the debug GSL CBLAS library (if any). GSL_CONFIG_EXECUTABLE - Location of the ``gsl-config`` script (if any). GSL_LIBRARY - Location of the GSL library. GSL_LIBRARY_DEBUG - Location of the debug GSL library (if any). FindGTest Locate the Google C++ Testing Framework. Imported targets This module defines the following IMPORTED targets: GTest::GTest The Google Test gtest library, if found; adds Thread::Thread automatically GTest::Main The Google Test gtest_main library, if found Result variables This module will set the following variables in your project: GTEST_FOUND Found the Google Testing framework GTEST_INCLUDE_DIRS the directory containing the Google Test headers The library variables below are set as normal variables. These contain debug/optimized keywords when a debugging library is found. GTEST_LIBRARIES The Google Test gtest library; note it also requires linking with an appropriate thread library GTEST_MAIN_LIBRARIES The Google Test gtest_main library GTEST_BOTH_LIBRARIES Both gtest and gtest_main Cache variables The following cache variables may also be set: GTEST_ROOT The root directory of the Google Test installation (may also be set as an environ‐ ment variable) GTEST_MSVC_SEARCH If compiling with MSVC, this variable can be set to MD or MT (the default) to enable searching a GTest build tree Example usage enable_testing() find_package(GTest REQUIRED) add_executable(foo foo.cc) target_link_libraries(foo GTest::GTest GTest::Main) add_test(AllTestsInFoo foo) Deeper integration with CTest If you would like each Google test to show up in CTest as a test you may use the following macro: GTEST_ADD_TESTS(executable extra_args files...) executable the path to the test executable extra_args a list of extra arguments to be passed to executable enclosed in quotes (or "" for none) files... a list of source files to search for tests and test fixtures. Or AUTO to find them from executable target However, note that this macro will slow down your tests by running an executable for each test and test fixture. You will also have to re-run CMake after adding or removing tests or test fixtures. Example usage: set(FooTestArgs --foo 1 --bar 2) add_executable(FooTest FooUnitTest.cc) GTEST_ADD_TESTS(FooTest "${FooTestArgs}" AUTO) FindGTK2 FindGTK2.cmake This module can find the GTK2 widget libraries and several of its other optional compo‐ nents like gtkmm, glade, and glademm. NOTE: If you intend to use version checking, CMake 2.6.2 or later is required. Specify one or more of the following components as you call this find module. See example below. gtk gtkmm glade glademm The following variables will be defined for your use GTK2_FOUND - Were all of your specified components found? GTK2_INCLUDE_DIRS - All include directories GTK2_LIBRARIES - All libraries GTK2_TARGETS - All imported targets GTK2_DEFINITIONS - Additional compiler flags GTK2_VERSION - The version of GTK2 found (x.y.z) GTK2_MAJOR_VERSION - The major version of GTK2 GTK2_MINOR_VERSION - The minor version of GTK2 GTK2_PATCH_VERSION - The patch version of GTK2 Optional variables you can define prior to calling this module: GTK2_DEBUG - Enables verbose debugging of the module GTK2_ADDITIONAL_SUFFIXES - Allows defining additional directories to search for include files ================= Example Usage: Call find_package() once, here are some examples to pick from: Require GTK 2.6 or later find_package(GTK2 2.6 REQUIRED gtk) Require GTK 2.10 or later and Glade find_package(GTK2 2.10 REQUIRED gtk glade) Search for GTK/GTKMM 2.8 or later find_package(GTK2 2.8 COMPONENTS gtk gtkmm) if(GTK2_FOUND) include_directories(${GTK2_INCLUDE_DIRS}) add_executable(mygui mygui.cc) target_link_libraries(mygui ${GTK2_LIBRARIES}) endif() FindGTK try to find GTK (and glib) and GTKGLArea GTK_INCLUDE_DIR - Directories to include to use GTK GTK_LIBRARIES - Files to link against to use GTK GTK_FOUND - GTK was found GTK_GL_FOUND - GTK's GL features were found FindHDF5 Find HDF5, a library for reading and writing self describing array data. This module invokes the HDF5 wrapper compiler that should be installed alongside HDF5. Depending upon the HDF5 Configuration, the wrapper compiler is called either h5cc or h5pcc. If this succeeds, the module will then call the compiler with the -show argument to see what flags are used when compiling an HDF5 client application. The module will optionally accept the COMPONENTS argument. If no COMPONENTS are speci‐ fied, then the find module will default to finding only the HDF5 C library. If one or more COMPONENTS are specified, the module will attempt to find the language bindings for the specified components. The only valid components are C, CXX, Fortran, HL, and For‐ tran_HL. If the COMPONENTS argument is not given, the module will attempt to find only the C bindings. On UNIX systems, this module will read the variable HDF5_USE_STATIC_LIBRARIES to determine whether or not to prefer a static link to a dynamic link for HDF5 and all of it's depen‐ dencies. To use this feature, make sure that the HDF5_USE_STATIC_LIBRARIES variable is set before the call to find_package. To provide the module with a hint about where to find your HDF5 installation, you can set the environment variable HDF5_ROOT. The Find module will then look in this path when searching for HDF5 executables, paths, and libraries. Both the serial and parallel HDF5 wrappers are considered and the first directory to con‐ tain either one will be used. In the event that both appear in the same directory the serial version is preferentially selected. This behavior can be reversed by setting the variable HDF5_PREFER_PARALLEL to true. In addition to finding the includes and libraries required to compile an HDF5 client application, this module also makes an effort to find tools that come with the HDF5 dis‐ tribution that may be useful for regression testing. This module will define the following variables: HDF5_INCLUDE_DIRS - Location of the hdf5 includes HDF5_INCLUDE_DIR - Location of the hdf5 includes (deprecated) HDF5_DEFINITIONS - Required compiler definitions for HDF5 HDF5_C_LIBRARIES - Required libraries for the HDF5 C bindings. HDF5_CXX_LIBRARIES - Required libraries for the HDF5 C++ bindings HDF5_Fortran_LIBRARIES - Required libraries for the HDF5 Fortran bindings HDF5_HL_LIBRARIES - Required libraries for the HDF5 high level API HDF5_Fortran_HL_LIBRARIES - Required libraries for the high level Fortran bindings. HDF5_LIBRARIES - Required libraries for all requested bindings HDF5_FOUND - true if HDF5 was found on the system HDF5_VERSION - HDF5 version in format Major.Minor.Release HDF5_LIBRARY_DIRS - the full set of library directories HDF5_IS_PARALLEL - Whether or not HDF5 was found with parallel IO support HDF5_C_COMPILER_EXECUTABLE - the path to the HDF5 C wrapper compiler HDF5_CXX_COMPILER_EXECUTABLE - the path to the HDF5 C++ wrapper compiler HDF5_Fortran_COMPILER_EXECUTABLE - the path to the HDF5 Fortran wrapper compiler HDF5_DIFF_EXECUTABLE - the path to the HDF5 dataset comparison tool FindHg Extract information from a mercurial working copy. The module defines the following variables: HG_EXECUTABLE - path to mercurial command line client (hg) HG_FOUND - true if the command line client was found HG_VERSION_STRING - the version of mercurial found If the command line client executable is found the following macro is defined: HG_WC_INFO(<dir> <var-prefix>) Hg_WC_INFO extracts information of a mercurial working copy at a given location. This macro defines the following variables: <var-prefix>_WC_CHANGESET - current changeset <var-prefix>_WC_REVISION - current revision Example usage: find_package(Hg) if(HG_FOUND) message("hg found: ${HG_EXECUTABLE}") HG_WC_INFO(${PROJECT_SOURCE_DIR} Project) message("Current revision is ${Project_WC_REVISION}") message("Current changeset is ${Project_WC_CHANGESET}") endif() FindHSPELL Try to find Hspell Once done this will define HSPELL_FOUND - system has Hspell HSPELL_INCLUDE_DIR - the Hspell include directory HSPELL_LIBRARIES - The libraries needed to use Hspell HSPELL_DEFINITIONS - Compiler switches required for using Hspell HSPELL_VERSION_STRING - The version of Hspell found (x.y) HSPELL_MAJOR_VERSION - the major version of Hspell HSPELL_MINOR_VERSION - The minor version of Hspell FindHTMLHelp This module looks for Microsoft HTML Help Compiler It defines: HTML_HELP_COMPILER : full path to the Compiler (hhc.exe) HTML_HELP_INCLUDE_PATH : include path to the API (htmlhelp.h) HTML_HELP_LIBRARY : full path to the library (htmlhelp.lib) FindIce Find the ZeroC Internet Communication Engine (ICE) programs, libraries and datafiles. This module supports multiple components. Components can include any of: Freeze, Glacier2, Ice, IceBox, IceDB, IceGrid, IcePatch, IceSSL, IceStorm, IceUtil, IceXML, or Slice.

This module reads hints about search results from: Ice_HOME - the root of the Ice installation The environment variable ICE_HOME may also be used; the Ice_HOME variable takes prece‐ dence. The following cache variables may also be set: Ice_<P>_EXECUTABLE - the path to executable <P> Ice_INCLUDE_DIR - the directory containing the Ice headers Ice_SLICE_DIR - the directory containing the Ice slice interface definitions Ice_<C>_LIBRARY - the library for component <C> NOTE: In most cases none of the above variables will require setting, unless multiple Ice versions are available and a specific version is required. On Windows, the most recent version of Ice will be found through the registry. On Unix, the programs, headers and libraries will usually be in standard locations, but Ice_SLICE_DIRS might not be auto‐ matically detected (commonly known locations are searched). All the other variables are defaulted using Ice_HOME, if set. It's possible to set Ice_HOME and selectively specify alternative locations for the other components; this might be required for e.g. newer versions of Visual Studio if the heuristics are not sufficient to identify the correct programs and libraries for the specific Visual Studio version. Other variables one may set to control this module are: Ice_DEBUG - Set to ON to enable debug output from FindIce. FindIcotool Find icotool This module looks for icotool. This module defines the following values: ICOTOOL_EXECUTABLE: the full path to the icotool tool. ICOTOOL_FOUND: True if icotool has been found. ICOTOOL_VERSION_STRING: the version of icotool found. FindImageMagick Find the ImageMagick binary suite. This module will search for a set of ImageMagick tools specified as components in the FIND_PACKAGE call. Typical components include, but are not limited to (future versions of ImageMagick might have additional components not listed here): animate compare composite conjure convert display identify import mogrify montage stream If no component is specified in the FIND_PACKAGE call, then it only searches for the ImageMagick executable directory. This code defines the following variables: ImageMagick_FOUND - TRUE if all components are found. ImageMagick_EXECUTABLE_DIR - Full path to executables directory. ImageMagick_<component>_FOUND - TRUE if <component> is found. ImageMagick_<component>_EXECUTABLE - Full path to <component> executable. ImageMagick_VERSION_STRING - the version of ImageMagick found (since CMake 2.8.8) ImageMagick_VERSION_STRING will not work for old versions like 5.2.3. There are also components for the following ImageMagick APIs: Magick++ MagickWand MagickCore For these components the following variables are set: ImageMagick_FOUND - TRUE if all components are found. ImageMagick_INCLUDE_DIRS - Full paths to all include dirs. ImageMagick_LIBRARIES - Full paths to all libraries. ImageMagick_<component>_FOUND - TRUE if <component> is found. ImageMagick_<component>_INCLUDE_DIRS - Full path to <component> include dirs. ImageMagick_<component>_LIBRARIES - Full path to <component> libraries. Example Usages: find_package(ImageMagick) find_package(ImageMagick COMPONENTS convert) find_package(ImageMagick COMPONENTS convert mogrify display) find_package(ImageMagick COMPONENTS Magick++) find_package(ImageMagick COMPONENTS Magick++ convert) Note that the standard FIND_PACKAGE features are supported (i.e., QUIET, REQUIRED, etc.).

General variables: Intl_FOUND - true if the libintl headers and libraries were found Intl_INCLUDE_DIRS - the directory containing the libintl headers Intl_LIBRARIES - libintl libraries to be linked The following cache variables may also be set: Intl_INCLUDE_DIR - the directory containing the libintl headers Intl_LIBRARY - the libintl library (if any) NOTE: On some platforms, such as Linux with GNU libc, the gettext functions are present in the C standard library and libintl is not required. Intl_LIBRARIES will be empty in this case. NOTE: If you wish to use the Gettext tools (msgmerge, msgfmt, etc.), use FindGettext. FindITK This module no longer exists. This module existed in versions of CMake prior to 3.1, but became only a thin wrapper around find_package(ITK NO_MODULE) to provide compatibility for projects using long-out‐ dated conventions. Now find_package(ITK) will search for ITKConfig.cmake directly. FindJasper Try to find the Jasper JPEG2000 library Once done this will define JASPER_FOUND - system has Jasper JASPER_INCLUDE_DIR - the Jasper include directory JASPER_LIBRARIES - the libraries needed to use Jasper JASPER_VERSION_STRING - the version of Jasper found (since CMake 2.8.8) FindJava Find Java This module finds if Java is installed and determines where the include files and libraries are.

KDE3_AUTOMOC(file1 ... fileN) Call this if you want to have automatic moc file handling. This means if you include "foo.moc" in the source file foo.cpp a moc file for the header foo.h will be created automatically. You can set the property SKIP_AUTOMAKE using set_source_files_properties() to exclude some files in the list from being processed. KDE3_ADD_MOC_FILES(SRCS_VAR file1 ... fileN ) If you don't use the KDE3_AUTOMOC() macro, for the files listed here moc files will be created (named "foo.moc.cpp") KDE3_ADD_DCOP_SKELS(SRCS_VAR header1.h ... headerN.h ) Use this to generate DCOP skeletions from the listed headers. KDE3_ADD_DCOP_STUBS(SRCS_VAR header1.h ... headerN.h ) Use this to generate DCOP stubs from the listed headers. KDE3_ADD_UI_FILES(SRCS_VAR file1.ui ... fileN.ui ) Use this to add the Qt designer ui files to your application/library. KDE3_ADD_KCFG_FILES(SRCS_VAR file1.kcfgc ... fileN.kcfgc ) Use this to add KDE kconfig compiler files to your application/library. KDE3_INSTALL_LIBTOOL_FILE(target) This will create and install a simple libtool file for the given target. KDE3_ADD_EXECUTABLE(name file1 ... fileN ) Currently identical to add_executable(), may provide some advanced features in the future. KDE3_ADD_KPART(name [WITH_PREFIX] file1 ... fileN ) Create a KDE plugin (KPart, kioslave, etc.) from the given source files. If WITH_PREFIX is given, the resulting plugin will have the prefix "lib", otherwise it won't. It creates and installs an appropriate libtool la-file. KDE3_ADD_KDEINIT_EXECUTABLE(name file1 ... fileN ) Create a KDE application in the form of a module loadable via kdeinit. A library named kdeinit_<name> will be created and a small executable which links to it. The option KDE3_ENABLE_FINAL to enable all-in-one compilation is no longer supported.

This package first intention is to find the libraries associated with Matlab in order to be able to build Matlab extensions (mex files). It can also be used: · run specific commands in Matlab · declare Matlab unit test · retrieve various information from Matlab (mex extensions, versions and release queries, ...) The module supports the following components: · MX_LIBRARY and ENG_LIBRARY respectively the MX and ENG libraries of Matlab · MAIN_PROGRAM the Matlab binary program. NOTE: The version given to the find_package() directive is the Matlab version, which should not be confused with the Matlab release name (eg. R2014). The matlab_get_version_from_release_name() and matlab_get_release_name_from_version() allow a mapping from the release name to the version. The variable Matlab_ROOT_DIR may be specified in order to give the path of the desired Matlab version. Otherwise, the behaviour is platform specific: · Windows: The installed versions of Matlab are retrieved from the Windows registry · OS X: The installed versions of Matlab are given by the MATLAB paths in /Application. If no such application is found, it falls back to the one that might be accessible from the PATH. · Unix: The desired Matlab should be accessible from the PATH. Additional information is provided when MATLAB_FIND_DEBUG is set. When a Matlab binary is found automatically and the MATLAB_VERSION is not given, the version is queried from Mat‐ lab directly. On Windows, it can make a window running Matlab appear. The mapping of the release names and the version of Matlab is performed by defining pairs (name, version). The variable MATLAB_ADDITIONAL_VERSIONS may be provided before the call to the find_package() in order to handle additional versions. A Matlab scripts can be added to the set of tests using the matlab_add_unit_test(). By default, the Matlab unit test framework will be used (>= 2013a) to run this script, but regular .m files returning an exit code can be used as well (0 indicating a success). Module Input Variables Users or projects may set the following variables to configure the module behaviour: Matlab_ROOT_DIR the root of the Matlab installation. MATLAB_FIND_DEBUG outputs debug information MATLAB_ADDITIONAL_VERSIONS additional versions of Matlab for the automatic retrieval of the installed ver‐ sions. Variables defined by the module Result variables Matlab_FOUND TRUE if the Matlab installation is found, FALSE otherwise. All variable below are defined if Matlab is found. Matlab_ROOT_DIR the final root of the Matlab installation determined by the FindMatlab module. Matlab_MAIN_PROGRAM the Matlab binary program. Available only if the component MAIN_PROGRAM is given in the find_package() directive. Matlab_INCLUDE_DIRS the path of the Matlab libraries headers Matlab_MEX_LIBRARY library for mex, always available. Matlab_MX_LIBRARY mx library of Matlab (arrays). Available only if the component MX_LIBRARY has been requested. Matlab_ENG_LIBRARY Matlab engine library. Available only if the component ENG_LIBRARY is requested. Matlab_LIBRARIES the whole set of libraries of Matlab Matlab_MEX_COMPILER the mex compiler of Matlab. Currently not used. Available only if the component MEX_COMPILER is asked Cached variables Matlab_MEX_EXTENSION the extension of the mex files for the current platform (given by Matlab). Matlab_ROOT_DIR the location of the root of the Matlab installation found. If this value is changed by the user, the result variables are recomputed. Provided macros matlab_get_version_from_release_name() returns the version from the release name matlab_get_release_name_from_version() returns the release name from the Matlab version Provided functions matlab_add_mex() adds a target compiling a MEX file. matlab_add_unit_test() adds a Matlab unit test file as a test to the project. matlab_extract_all_installed_versions_from_registry() parses the registry for all Matlab versions. Available on Windows only. The part of the registry parsed is dependent on the host processor matlab_get_all_valid_matlab_roots_from_registry() returns all the possible Matlab paths, according to a previously given list. Only the existing/accessible paths are kept. This is mainly useful for the searching all possible Matlab installation. matlab_get_mex_suffix() returns the suffix to be used for the mex files (platform/architecture dependant) matlab_get_version_from_matlab_run() returns the version of Matlab, given the full directory of the Matlab program. Known issues Symbol clash in a MEX target By default, every symbols inside a MEX file defined with the command matlab_add_mex() have hidden visibility, except for the entry point. This is the default behaviour of the MEX compiler, which lowers the risk of symbol collision between the libraries shipped with Matlab, and the libraries to which the MEX file is linking to. This is also the default on Windows platforms. However, this is not sufficient in certain case, where for instance your MEX file is linking against libraries that are already loaded by Matlab, even if those libraries have different SONAMES. A possible solution is to hide the symbols of the libraries to which the MEX target is linking to. This can be achieved in GNU GCC compilers with the linker option -Wl,--exclude-libs,ALL. Tests using GPU resources in case your MEX file is using the GPU and in order to be able to run unit tests on this MEX file, the GPU resources should be properly released by Matlab. A possible solution is to make Matlab aware of the use of the GPU resources in the session, which can be performed by a command such as D = gpuDevice() at the beginning of the test script (or via a fixture). Reference Matlab_ROOT_DIR The root folder of the Matlab installation. If set before the call to find_pack‐ age(), the module will look for the components in that path. If not set, then an automatic search of Matlab will be performed. If set, it should point to a valid version of Matlab. MATLAB_FIND_DEBUG If set, the lookup of Matlab and the intermediate configuration steps are outputted to the console. MATLAB_ADDITIONAL_VERSIONS If set, specifies additional versions of Matlab that may be looked for. The vari‐ able should be a list of strings, organised by pairs of release name and versions, such as follows: set(MATLAB_ADDITIONAL_VERSIONS "release_name1=corresponding_version1" "release_name2=corresponding_version2" ... ) Example: set(MATLAB_ADDITIONAL_VERSIONS "R2013b=8.2" "R2013a=8.1" "R2012b=8.0") The order of entries in this list matters when several versions of Matlab are installed. The priority is set according to the ordering in this list. matlab_get_version_from_release_name Returns the version of Matlab (17.58) from a release name (R2017k) matlab_get_release_name_from_version Returns the release name (R2017k) from the version of Matlab (17.58) matlab_extract_all_installed_versions_from_registry This function parses the registry and founds the Matlab versions that are installed. The found versions are returned in matlab_versions. Set win64 to TRUE if the 64 bit version of Matlab should be looked for The returned list contains all versions under HKLM\\SOFTWARE\\Mathworks\\MATLAB or an empty list in case an error occurred (or nothing found). NOTE: Only the versions are provided. No check is made over the existence of the installation referenced in the registry, matlab_get_all_valid_matlab_roots_from_registry Populates the Matlab root with valid versions of Matlab. The returned matlab_roots is organized in pairs (version_number,matlab_root_path). matlab_get_all_valid_matlab_roots_from_registry( matlab_versions matlab_roots) matlab_versions the versions of each of the Matlab installations matlab_roots the location of each of the Matlab installations matlab_get_mex_suffix Returns the extension of the mex files (the suffixes). This function should not be called before the appropriate Matlab root has been found. matlab_get_mex_suffix( matlab_root mex_suffix) matlab_root the root of the Matlab installation mex_suffix the variable name in which the suffix will be returned. matlab_get_version_from_matlab_run This function runs Matlab program specified on arguments and extracts its version. matlab_get_version_from_matlab_run( matlab_binary_path matlab_list_versions) matlab_binary_path the location of the matlab binary executable matlab_list_versions the version extracted from Matlab matlab_add_unit_test Adds a Matlab unit test to the test set of cmake/ctest. This command requires the component MAIN_PROGRAM. The unit test uses the Matlab unittest framework (default, available starting Matlab 2013b+) except if the option NO_UNITTEST_FRAMEWORK is given. The function expects one Matlab test script file to be given. In the case NO_UNITTEST_FRAMEWORK is given, the unittest script file should contain the script to be run, plus an exit command with the exit value. This exit value will be passed to the ctest framework (0 success, non 0 failure). Additional arguments accepted by add_test() can be passed through TEST_ARGS (eg. CONFIGURATION <config> ...). matlab_add_unit_test( NAME <name> UNITTEST_FILE matlab_file_containing_unittest.m [UNITTEST_PRECOMMAND matlab_command_to_run] [TIMEOUT timeout] [ADDITIONAL_PATH path1 [path2 ...]] [MATLAB_ADDITIONAL_STARTUP_OPTIONS option1 [option2 ...]] [TEST_ARGS arg1 [arg2 ...]] [NO_UNITTEST_FRAMEWORK] ) The function arguments are: NAME name of the unittest in ctest. UNITTEST_FILE the matlab unittest file. Its path will be automatically added to the Matlab path. UNITTEST_PRECOMMAND Matlab script command to be ran before the file containing the test (eg. GPU device initialisation based on CMake variables). TIMEOUT the test timeout in seconds. Defaults to 180 seconds as the Matlab unit test may hang. ADDITIONAL_PATH a list of paths to add to the Matlab path prior to running the unit test. MATLAB_ADDITIONAL_STARTUP_OPTIONS a list of additional option in order to run Matlab from the command line. TEST_ARGS Additional options provided to the add_test command. These options are added to the default options (eg. "CONFIGURATIONS Release") NO_UNITTEST_FRAMEWORK when set, indicates that the test should not use the unittest framework of Matlab (available for versions >= R2013a). matlab_add_mex Adds a Matlab MEX target. This commands compiles the given sources with the cur‐ rent tool-chain in order to produce a MEX file. The final name of the produced out‐ put may be specified, as well as additional link libraries, and a documentation entry for the MEX file. Remaining arguments of the call are passed to the add_library() command. matlab_add_mex( NAME <name> SRC src1 [src2 ...] [OUTPUT_NAME output_name] [DOCUMENTATION file.txt] [LINK_TO target1 target2 ...] [...] ) NAME name of the target. SRC list of tje source files. LINK_TO a list of additional link dependencies. The target links to libmex by default. If Matlab_MX_LIBRARY is defined, it also links to libmx. OUTPUT_NAME if given, overrides the default name. The default name is the name of the target without any prefix and with Matlab_MEX_EXTENSION suffix. DOCUMENTATION if given, the file file.txt will be considered as being the documentation file for the MEX file. This file is copied into the same folder without any processing, with the same name as the final mex file, and with extension .m. In that case, typing help <name> in Matlab prints the documentation con‐ tained in this file. The documentation file is not processed and should be in the following format: % This is the documentation function ret = mex_target_output_name(input1) FindMFC Find MFC on Windows Find the native MFC - i.e. decide if an application can link to the MFC libraries. MFC_FOUND - Was MFC support found You don't need to include anything or link anything to use it. FindMotif Try to find Motif (or lesstif) Once done this will define: MOTIF_FOUND - system has MOTIF MOTIF_INCLUDE_DIR - include paths to use Motif MOTIF_LIBRARIES - Link these to use Motif FindMPEG2 Find the native MPEG2 includes and library This module defines MPEG2_INCLUDE_DIR, path to mpeg2dec/mpeg2.h, etc. MPEG2_LIBRARIES, the libraries required to use MPEG2. MPEG2_FOUND, If false, do not try to use MPEG2. also defined, but not for general use are MPEG2_mpeg2_LIBRARY, where to find the MPEG2 library. MPEG2_vo_LIBRARY, where to find the vo library. FindMPEG Find the native MPEG includes and library This module defines MPEG_INCLUDE_DIR, where to find MPEG.h, etc. MPEG_LIBRARIES, the libraries required to use MPEG. MPEG_FOUND, If false, do not try to use MPEG. also defined, but not for general use are MPEG_mpeg2_LIBRARY, where to find the MPEG library. MPEG_vo_LIBRARY, where to find the vo library. FindMPI Find a Message Passing Interface (MPI) implementation The Message Passing Interface (MPI) is a library used to write high-performance distrib‐ uted-memory parallel applications, and is typically deployed on a cluster. MPI is a stan‐ dard interface (defined by the MPI forum) for which many implementations are available. All of them have somewhat different include paths, libraries to link against, etc., and this module tries to smooth out those differences. === Variables === This module will set the following variables per language in your project, where <lang> is one of C, CXX, or Fortran: MPI_<lang>_FOUND TRUE if FindMPI found MPI flags for <lang> MPI_<lang>_COMPILER MPI Compiler wrapper for <lang> MPI_<lang>_COMPILE_FLAGS Compilation flags for MPI programs MPI_<lang>_INCLUDE_PATH Include path(s) for MPI header MPI_<lang>_LINK_FLAGS Linking flags for MPI programs MPI_<lang>_LIBRARIES All libraries to link MPI programs against Additionally, FindMPI sets the following variables for running MPI programs from the com‐ mand line: MPIEXEC Executable for running MPI programs MPIEXEC_NUMPROC_FLAG Flag to pass to MPIEXEC before giving it the number of processors to run on MPIEXEC_PREFLAGS Flags to pass to MPIEXEC directly before the executable to run. MPIEXEC_POSTFLAGS Flags to pass to MPIEXEC after other flags === Usage === To use this module, simply call FindMPI from a CMakeLists.txt file, or run find_pack‐ age(MPI), then run CMake. If you are happy with the auto- detected configuration for your language, then you're done. If not, you have two options: 1. Set MPI_<lang>_COMPILER to the MPI wrapper (mpicc, etc.) of your choice and reconfigure. FindMPI will attempt to determine all the necessary variables using THAT compiler's compile and link flags. 2. If this fails, or if your MPI implementation does not come with a compiler wrapper, then set both MPI_<lang>_LIBRARIES and MPI_<lang>_INCLUDE_PATH. You may also set any other variables listed above, but these two are required. This will circumvent autodetection entirely. When configuration is successful, MPI_<lang>_COMPILER will be set to the compiler wrapper for <lang>, if it was found. MPI_<lang>_FOUND and other variables above will be set if any MPI implementation was found for <lang>, regardless of whether a compiler was found. When using MPIEXEC to execute MPI applications, you should typically use all of the MPIEXEC flags as follows: ${MPIEXEC} ${MPIEXEC_NUMPROC_FLAG} PROCS ${MPIEXEC_PREFLAGS} EXECUTABLE ${MPIEXEC_POSTFLAGS} ARGS where PROCS is the number of processors on which to execute the program, EXECUTABLE is the MPI program, and ARGS are the arguments to pass to the MPI program. === Backward Compatibility === For backward compatibility with older versions of FindMPI, these variables are set, but deprecated: MPI_FOUND MPI_COMPILER MPI_LIBRARY MPI_COMPILE_FLAGS MPI_INCLUDE_PATH MPI_EXTRA_LIBRARY MPI_LINK_FLAGS MPI_LIBRARIES In new projects, please use the MPI_<lang>_XXX equivalents. FindOpenAL Locate OpenAL This module defines OPENAL_LIBRARY OPENAL_FOUND, if false, do not try to link to OpenAL OPENAL_INCLUDE_DIR, where to find the headers $OPENALDIR is an environment variable that would correspond to the Created by Eric Wing.

OPENGL_INCLUDE_DIR Path to the OpenGL include directory. OPENGL_LIBRARIES Paths to the OpenGL and GLU libraries. If you want to use just GL you can use these values: OPENGL_gl_LIBRARY Path to the OpenGL library. OPENGL_glu_LIBRARY Path to the GLU library. OSX Specific On OSX default to using the framework version of OpenGL. People will have to change the cache values of OPENGL_glu_LIBRARY and OPENGL_gl_LIBRARY to use OpenGL with X11 on OSX. FindOpenMP Finds OpenMP support This module can be used to detect OpenMP support in a compiler. If the compiler supports OpenMP, the flags required to compile with OpenMP support are returned in variables for the different languages. The variables may be empty if the compiler does not need a spe‐ cial flag to support OpenMP. The following variables are set: OpenMP_C_FLAGS - flags to add to the C compiler for OpenMP support OpenMP_CXX_FLAGS - flags to add to the CXX compiler for OpenMP support OpenMP_Fortran_FLAGS - flags to add to the Fortran compiler for OpenMP support OPENMP_FOUND - true if openmp is detected Supported compilers can be found at http://openmp.org/wp/openmp-compilers/ FindOpenSceneGraph Find OpenSceneGraph This module searches for the OpenSceneGraph core "osg" library as well as OpenThreads, and whatever additional COMPONENTS (nodekits) that you specify. See http://www.openscenegraph.org NOTE: To use this module effectively you must either require CMake >= 2.6.3 with cmake_minimum_required(VERSION 2.6.3) or download and place FindOpenThreads.cmake, Find‐ osg_functions.cmake, Findosg.cmake, and Find<etc>.cmake files into your CMAKE_MODULE_PATH. ---- This module accepts the following variables (note mixed case) OpenSceneGraph_DEBUG - Enable debugging output OpenSceneGraph_MARK_AS_ADVANCED - Mark cache variables as advanced automatically The following environment variables are also respected for finding the OSG and it's vari‐ ous components.

FindOpenThreads OpenThreads is a C++ based threading library. Its largest userbase seems to OpenScene‐ Graph so you might notice I accept OSGDIR as an environment path. I consider this part of the Findosg* suite used to find OpenSceneGraph components. Each component is separate and you must opt in to each module. Locate OpenThreads This module defines OPENTHREADS_LIBRARY OPENTHREADS_FOUND, if false, do not try to link to OpenThreads OPENTHREADS_INCLUDE_DIR, where to find the headers $OPENTHREADS_DIR is an environment variable that would correspond to the ./configure --prefix=$OPENTHREADS_DIR used in building osg.

This is to allow you control over your own system piece by piece in case you need to opt out of cer‐ tain components or change the Find behavior for a particular module (perhaps because the default FindOpenGL.cmake module doesn't work with your system as an example). If you want to use a more convenient module that includes everything, use the FindOpenSceneGraph.cmake instead of the Findosg*.cmake modules.

FindPackageHandleStandardArgs This module provides a function intended to be used in Find Modules implementing find_package(<PackageName>) calls. It handles the REQUIRED, QUIET and version-related arguments of find_package. It also sets the <PackageName>_FOUND variable. The package is considered found if all variables listed contain valid results, e.g. valid filepaths. find_package_handle_standard_args There are two signatures: find_package_handle_standard_args(<PackageName> (DEFAULT_MSG|<custom-failure-message>) <required-var>... ) find_package_handle_standard_args(<PackageName> [FOUND_VAR <result-var>] [REQUIRED_VARS <required-var>...] [VERSION_VAR <version-var>] [HANDLE_COMPONENTS] [CONFIG_MODE] [FAIL_MESSAGE <custom-failure-message>] ) The <PackageName>_FOUND variable will be set to TRUE if all the variables <required-var>... are valid and any optional constraints are satisfied, and FALSE otherwise. A success or failure message may be displayed based on the results and on whether the REQUIRED and/or QUIET option was given to the find_package() call. The options are: (DEFAULT_MSG|<custom-failure-message>) In the simple signature this specifies the failure message. Use DEFAULT_MSG to ask for a default message to be computed (recommended). Not valid in the full signature. FOUND_VAR <result-var> Obsolete. Specifies either <PackageName>_FOUND or <PACKAGENAME>_FOUND as the result variable. This exists only for compatibility with older versions of CMake and is now ignored. Result variables of both names are always set for compatibility. REQUIRED_VARS <required-var>... Specify the variables which are required for this package. These may be named in the generated failure message asking the user to set the missing variable values. Therefore these should typically be cache entries such as FOO_LIBRARY and not output variables like FOO_LIBRARIES. VERSION_VAR <version-var> Specify the name of a variable that holds the version of the package that has been found. This version will be checked against the (potentially) specified required version given to the find_package() call, including its EXACT option. The default messages include information about the required version and the version which has been actually found, both if the version is ok or not. HANDLE_COMPONENTS Enable handling of package components. In this case, the command will report which components have been found and which are missing, and the <PackageName>_FOUND variable will be set to FALSE if any of the required components (i.e. not the ones listed after the OPTIONAL_COMPONENTS option of find_package()) are missing. CONFIG_MODE Specify that the calling find module is a wrapper around a call to find_package(<PackageName> NO_MODULE). This implies a VERSION_VAR value of <PackageName>_VERSION. The command will automatically check whether the package configuration file was found. FAIL_MESSAGE <custom-failure-message> Specify a custom failure message instead of using the default generated mes‐ sage. Not recommended. Example for the simple signature: find_package_handle_standard_args(LibXml2 DEFAULT_MSG LIBXML2_LIBRARY LIBXML2_INCLUDE_DIR) The LibXml2 package is considered to be found if both LIBXML2_LIBRARY and LIBXML2_INCLUDE_DIR are valid. Then also LibXml2_FOUND is set to TRUE. If it is not found and REQUIRED was used, it fails with a message(FATAL_ERROR), independent whether QUIET was used or not. If it is found, success will be reported, including the content of the first <required-var>. On repeated CMake runs, the same message will not be printed again. Example for the full signature: find_package_handle_standard_args(LibArchive REQUIRED_VARS LibArchive_LIBRARY LibArchive_INCLUDE_DIR VERSION_VAR LibArchive_VERSION) In this case, the LibArchive package is considered to be found if both LibArchive_LIBRARY and LibArchive_INCLUDE_DIR are valid. Also the version of LibArchive will be checked by using the version contained in LibArchive_VERSION. Since no FAIL_MESSAGE is given, the default messages will be printed. Another example for the full signature: find_package(Automoc4 QUIET NO_MODULE HINTS /opt/automoc4) find_package_handle_standard_args(Automoc4 CONFIG_MODE) In this case, a FindAutmoc4.cmake module wraps a call to find_package(Automoc4 NO_MODULE) and adds an additional search directory for automoc4. Then the call to find_package_han‐ dle_standard_args produces a proper success/failure message. FindPackageMessage FIND_PACKAGE_MESSAGE(<name> "message for user" "find result details") This macro is intended to be used in FindXXX.cmake modules files. It will print a message once for each unique find result. This is useful for telling the user where a package was found. The first argument specifies the name (XXX) of the package. The second argument specifies the message to display. The third argument lists details about the find result so that if they change the message will be displayed again. The macro also obeys the QUIET argument to the find_package command. Example: if(X11_FOUND) FIND_PACKAGE_MESSAGE(X11 "Found X11: ${X11_X11_LIB}" "[${X11_X11_LIB}][${X11_INCLUDE_DIR}]") else() ... endif() FindPerlLibs Find Perl libraries This module finds if PERL is installed and determines where the include files and libraries are. It also determines what the name of the library is. This code sets the following variables: PERLLIBS_FOUND = True if perl.h & libperl were found PERL_INCLUDE_PATH = path to where perl.h is found PERL_LIBRARY = path to libperl PERL_EXECUTABLE = full path to the perl binary The minimum required version of Perl can be specified using the standard syntax, e.g. find_package(PerlLibs 6.0) The following variables are also available if needed (introduced after CMake 2.6.4) PERL_SITESEARCH = path to the sitesearch install dir PERL_SITELIB = path to the sitelib install directory PERL_VENDORARCH = path to the vendor arch install directory PERL_VENDORLIB = path to the vendor lib install directory PERL_ARCHLIB = path to the arch lib install directory PERL_PRIVLIB = path to the priv lib install directory PERL_EXTRA_C_FLAGS = Compilation flags used to build perl FindPerl Find perl this module looks for Perl PERL_EXECUTABLE - the full path to perl PERL_FOUND - If false, don't attempt to use perl. PERL_VERSION_STRING - version of perl found (since CMake 2.8.8) FindPHP4 Find PHP4 This module finds if PHP4 is installed and determines where the include files and libraries are. It also determines what the name of the library is. This code sets the following variables: PHP4_INCLUDE_PATH = path to where php.h can be found PHP4_EXECUTABLE = full path to the php4 binary FindPhysFS Locate PhysFS library This module defines PHYSFS_LIBRARY, the name of the library to link against PHYSFS_FOUND, if false, do not try to link to PHYSFS PHYSFS_INCLUDE_DIR, where to find physfs.h $PHYSFSDIR is an environment variable that would correspond to the Created by Eric Wing. FindPike Find Pike This module finds if PIKE is installed and determines where the include files and libraries are. It also determines what the name of the library is. This code sets the following variables: PIKE_INCLUDE_PATH = path to where program.h is found PIKE_EXECUTABLE = full path to the pike binary FindPkgConfig A pkg-config module for CMake. Finds the pkg-config executable and add the pkg_check_modules() and pkg_search_module() commands. In order to find the pkg-config executable, it uses the PKG_CONFIG_EXECUTABLE variable or the PKG_CONFIG environment variable first. pkg_get_variable Retrieves the value of a variable from a package: pkg_get_variable(<RESULT> <MODULE> <VARIABLE>) For example: pkg_get_variable(GI_GIRDIR gobject-introspection-1.0 girdir) pkg_check_modules Checks for all the given modules. pkg_check_modules(<PREFIX> [REQUIRED] [QUIET] [NO_CMAKE_PATH] [NO_CMAKE_ENVIRONMENT_PATH] <MODULE> [<MODULE>]*) When the REQUIRED argument was set, macros will fail with an error when module(s) could not be found. When the QUIET argument is set, no status messages will be printed. By default, if CMAKE_MINIMUM_REQUIRED_VERSION is 3.1 or later, or if PKG_CONFIG_USE_CMAKE_PREFIX_PATH is set, the CMAKE_PREFIX_PATH, CMAKE_FRAME‐ WORK_PATH, and CMAKE_APPBUNDLE_PATH cache and environment variables will be added to pkg-config search path. The NO_CMAKE_PATH and NO_CMAKE_ENVIRONMENT_PATH argu‐ ments disable this behavior for the cache variables and the environment variables, respectively. It sets the following variables: PKG_CONFIG_FOUND ... if pkg-config executable was found PKG_CONFIG_EXECUTABLE ... pathname of the pkg-config program PKG_CONFIG_VERSION_STRING ... the version of the pkg-config program found (since CMake 2.8.8) For the following variables two sets of values exist; first one is the common one and has the given PREFIX. The second set contains flags which are given out when pkg-config was called with the --static option. <XPREFIX>_FOUND ... set to 1 if module(s) exist <XPREFIX>_LIBRARIES ... only the libraries (w/o the '-l') <XPREFIX>_LIBRARY_DIRS ... the paths of the libraries (w/o the '-L') <XPREFIX>_LDFLAGS ... all required linker flags <XPREFIX>_LDFLAGS_OTHER ... all other linker flags <XPREFIX>_INCLUDE_DIRS ... the '-I' preprocessor flags (w/o the '-I') <XPREFIX>_CFLAGS ... all required cflags <XPREFIX>_CFLAGS_OTHER ... the other compiler flags <XPREFIX> = <PREFIX> for common case <XPREFIX> = <PREFIX>_STATIC for static linking There are some special variables whose prefix depends on the count of given mod‐ ules. When there is only one module, <PREFIX> stays unchanged. When there are multiple modules, the prefix will be changed to <PREFIX>_<MODNAME>: <XPREFIX>_VERSION ... version of the module <XPREFIX>_PREFIX ... prefix-directory of the module <XPREFIX>_INCLUDEDIR ... include-dir of the module <XPREFIX>_LIBDIR ... lib-dir of the module <XPREFIX> = <PREFIX> when |MODULES| == 1, else <XPREFIX> = <PREFIX>_<MODNAME> A <MODULE> parameter can have the following formats: {MODNAME} ... matches any version {MODNAME}>={VERSION} ... at least version <VERSION> is required {MODNAME}={VERSION} ... exactly version <VERSION> is required {MODNAME}<={VERSION} ... modules must not be newer than <VERSION> Examples pkg_check_modules (GLIB2 glib-2.0) pkg_check_modules (GLIB2 glib-2.0>=2.10) Requires at least version 2.10 of glib2 and defines e.g. GLIB2_VERSION=2.10.3 pkg_check_modules (FOO glib-2.0>=2.10 gtk+-2.0) Requires both glib2 and gtk2, and defines e.g. FOO_glib-2.0_VERSION=2.10.3 and FOO_gtk+-2.0_VERSION=2.8.20 pkg_check_modules (XRENDER REQUIRED xrender) Defines for example: XRENDER_LIBRARIES=Xrender;X11`` XRENDER_STATIC_LIBRARIES=Xrender;X11;pthread;Xau;Xdmcp pkg_search_module Same as pkg_check_modules(), but instead it checks for given modules and uses the first working one. pkg_search_module(<PREFIX> [REQUIRED] [QUIET] [NO_CMAKE_PATH] [NO_CMAKE_ENVIRONMENT_PATH] <MODULE> [<MODULE>]*) Examples pkg_search_module (BAR libxml-2.0 libxml2 libxml>=2) PKG_CONFIG_EXECUTABLE Path to the pkg-config executable. PKG_CONFIG_USE_CMAKE_PREFIX_PATH Whether pkg_check_modules() and pkg_search_module() should add the paths in CMAKE_PREFIX_PATH, CMAKE_FRAMEWORK_PATH, and CMAKE_APPBUNDLE_PATH cache and envi‐ ronment variables to pkg-config search path. If this variable is not set, this behavior is enabled by default if CMAKE_MINI‐ MUM_REQUIRED_VERSION is 3.1 or later, disabled otherwise. FindPNG Find libpng, the official reference library for the PNG image format. Imported targets This module defines the following IMPORTED target: PNG::PNG The libpng library, if found. Result variables This module will set the following variables in your project: PNG_INCLUDE_DIRS where to find png.h, etc. PNG_LIBRARIES the libraries to link against to use PNG. PNG_DEFINITIONS You should add_definitons(${PNG_DEFINITIONS}) before compiling code that includes png library files. PNG_FOUND If false, do not try to use PNG. PNG_VERSION_STRING the version of the PNG library found (since CMake 2.8.8) Obsolete variables The following variables may also be set, for backwards compatibility: PNG_LIBRARY where to find the PNG library. PNG_INCLUDE_DIR where to find the PNG headers (same as PNG_INCLUDE_DIRS) Since PNG depends on the ZLib compression library, none of the above will be defined unless ZLib can be found. FindPostgreSQL Find the PostgreSQL installation. This module defines PostgreSQL_LIBRARIES - the PostgreSQL libraries needed for linking PostgreSQL_INCLUDE_DIRS - the directories of the PostgreSQL headers PostgreSQL_LIBRARY_DIRS - the link directories for PostgreSQL libraries PostgreSQL_VERSION_STRING - the version of PostgreSQL found (since CMake 2.8.8) FindProducer Though Producer isn't directly part of OpenSceneGraph, its primary user is OSG so I con‐ sider this part of the Findosg* suite used to find OpenSceneGraph components. You'll notice that I accept OSGDIR as an environment path. Each component is separate and you must opt in to each module. You must also opt into OpenGL (and OpenThreads?) as these modules won't do it for you. This is to allow you con‐ trol over your own system piece by piece in case you need to opt out of certain components or change the Find behavior for a particular module (perhaps because the default Find‐ OpenGL.cmake module doesn't work with your system as an example). If you want to use a more convenient module that includes everything, use the FindOpenSceneGraph.cmake instead of the Findosg*.cmake modules.

This code sets the following variables: PYTHONINTERP_FOUND - Was the Python executable found PYTHON_EXECUTABLE - path to the Python interpreter PYTHON_VERSION_STRING - Python version found e.g. 2.5.2 PYTHON_VERSION_MAJOR - Python major version found e.g. 2 PYTHON_VERSION_MINOR - Python minor version found e.g. 5 PYTHON_VERSION_PATCH - Python patch version found e.g. 2 The Python_ADDITIONAL_VERSIONS variable can be used to specify a list of version numbers that should be taken into account when searching for Python. You need to set this vari‐ able before calling find_package(PythonInterp). If calling both find_package(PythonInterp) and find_package(PythonLibs), call find_pack‐ age(PythonInterp) first to get the currently active Python version by default with a con‐ sistent version of PYTHON_LIBRARIES. FindPythonLibs Find python libraries This module finds if Python is installed and determines where the include files and libraries are. It also determines what the name of the library is. This code sets the following variables: PYTHONLIBS_FOUND - have the Python libs been found PYTHON_LIBRARIES - path to the python library PYTHON_INCLUDE_PATH - path to where Python.h is found (deprecated) PYTHON_INCLUDE_DIRS - path to where Python.h is found PYTHON_DEBUG_LIBRARIES - path to the debug library (deprecated) PYTHONLIBS_VERSION_STRING - version of the Python libs found (since CMake 2.8.8) The Python_ADDITIONAL_VERSIONS variable can be used to specify a list of version numbers that should be taken into account when searching for Python. You need to set this vari‐ able before calling find_package(PythonLibs). If you'd like to specify the installation of Python to use, you should modify the follow‐ ing cache variables: PYTHON_LIBRARY - path to the python library PYTHON_INCLUDE_DIR - path to where Python.h is found If calling both find_package(PythonInterp) and find_package(PythonLibs), call find_pack‐ age(PythonInterp) first to get the currently active Python version by default with a con‐ sistent version of PYTHON_LIBRARIES. FindQt3 Locate Qt include paths and libraries This module defines: QT_INCLUDE_DIR - where to find qt.h, etc. QT_LIBRARIES - the libraries to link against to use Qt. QT_DEFINITIONS - definitions to use when compiling code that uses Qt. QT_FOUND - If false, don't try to use Qt. QT_VERSION_STRING - the version of Qt found If you need the multithreaded version of Qt, set QT_MT_REQUIRED to TRUE Also defined, but not for general use are: QT_MOC_EXECUTABLE, where to find the moc tool. QT_UIC_EXECUTABLE, where to find the uic tool. QT_QT_LIBRARY, where to find the Qt library. QT_QTMAIN_LIBRARY, where to find the qtmain library. This is only required by Qt3 on Windows. FindQt4 Finding and Using Qt4 This module can be used to find Qt4. The most important issue is that the Qt4 qmake is available via the system path. This qmake is then used to detect basically everything else. This module defines a number of IMPORTED targets, macros and variables. Typical usage could be something like: set(CMAKE_AUTOMOC ON) set(CMAKE_INCLUDE_CURRENT_DIR ON) find_package(Qt4 4.4.3 REQUIRED QtGui QtXml) add_executable(myexe main.cpp) target_link_libraries(myexe Qt4::QtGui Qt4::QtXml) NOTE: When using IMPORTED targets, the qtmain.lib static library is automatically linked on Windows for WIN32 executables. To disable that globally, set the QT4_NO_LINK_QTMAIN variable before finding Qt4. To disable that for a particular executable, set the QT4_NO_LINK_QTMAIN target property to TRUE on the executable. Qt Build Tools Qt relies on some bundled tools for code generation, such as moc for meta-object code gen‐ eration,``uic`` for widget layout and population, and rcc for virtual filesystem content generation. These tools may be automatically invoked by cmake(1) if the appropriate con‐ ditions are met. See cmake-qt(7) for more. Qt Macros In some cases it can be necessary or useful to invoke the Qt build tools in a more-manual way. Several macros are available to add targets for such uses. macro QT4_WRAP_CPP(outfiles inputfile ... [TARGET tgt] OPTIONS ...) create moc code from a list of files containing Qt class with the Q_OBJECT declaration. Per-directory preprocessor definitions are also added. If the <tgt> is specified, the INTERFACE_INCLUDE_DIRECTORIES and INTERFACE_COMPILE_DEFINITIONS from the <tgt> are passed to moc. Options may be given to moc, such as those found when executing "moc -help". macro QT4_WRAP_UI(outfiles inputfile ... OPTIONS ...) create code from a list of Qt designer ui files. Options may be given to uic, such as those found when executing "uic -help" macro QT4_ADD_RESOURCES(outfiles inputfile ... OPTIONS ...) create code from a list of Qt resource files. Options may be given to rcc, such as those found when executing "rcc -help" macro QT4_GENERATE_MOC(inputfile outputfile [TARGET tgt]) creates a rule to run moc on infile and create outfile. Use this if for some reason QT4_WRAP_CPP() isn't appropriate, e.g. because you need a custom filename for the moc file or something similar. If the <tgt> is specified, the INTERFACE_INCLUDE_DIRECTORIES and INTERFACE_COMPILE_DEFINITIONS from the <tgt> are passed to moc. macro QT4_ADD_DBUS_INTERFACE(outfiles interface basename) Create the interface header and implementation files with the given basename from the given interface xml file and add it to the list of sources. You can pass additional parameters to the qdbusxml2cpp call by setting properties on the input file: INCLUDE the given file will be included in the generate interface header CLASSNAME the generated class is named accordingly NO_NAMESPACE the generated class is not wrapped in a namespace macro QT4_ADD_DBUS_INTERFACES(outfiles inputfile ... ) Create the interface header and implementation files for all listed interface xml files. The basename will be automatically determined from the name of the xml file. The source file properties described for QT4_ADD_DBUS_INTERFACE also apply here. macro QT4_ADD_DBUS_ADAPTOR(outfiles xmlfile parentheader parentclassname [basename] [classname]) create a dbus adaptor (header and implementation file) from the xml file describing the interface, and add it to the list of sources. The adaptor forwards the calls to a parent class, defined in parentheader and named parentclassname. The name of the generated files will be <basename>adaptor.{cpp,h} where basename defaults to the basename of the xml file. If <classname> is provided, then it will be used as the classname of the adaptor itself. macro QT4_GENERATE_DBUS_INTERFACE( header [interfacename] OPTIONS ...) generate the xml interface file from the given header. If the optional argument interfacename is omitted, the name of the interface file is constructed from the basename of the header with the suffix .xml appended. Options may be given to qdbuscpp2xml, such as those found when executing "qdbuscpp2xml --help" macro QT4_CREATE_TRANSLATION( qm_files directories ... sources ... ts_files ... OPTIONS ...) out: qm_files in: directories sources ts_files options: flags to pass to lupdate, such as -extensions to specify extensions for a directory scan. generates commands to create .ts (vie lupdate) and .qm (via lrelease) - files from directories and/or sources. The ts files are created and/or updated in the source tree (unless given with full paths). The qm files are generated in the build tree. Updating the translations can be done by adding the qm_files to the source list of your library/executable, so they are always updated, or by adding a custom target to control when they get updated/generated. macro QT4_ADD_TRANSLATION( qm_files ts_files ... ) out: qm_files in: ts_files generates commands to create .qm from .ts - files. The generated filenames can be found in qm_files. The ts_files must exist and are not updated in any way. macro QT4_AUTOMOC(sourcefile1 sourcefile2 ... [TARGET tgt]) The qt4_automoc macro is obsolete. Use the CMAKE_AUTOMOC feature instead. This macro is still experimental. It can be used to have moc automatically handled. So if you have the files foo.h and foo.cpp, and in foo.h a a class uses the Q_OBJECT macro, moc has to run on it. If you don't want to use QT4_WRAP_CPP() (which is reliable and mature), you can insert #include "foo.moc" in foo.cpp and then give foo.cpp as argument to QT4_AUTOMOC(). This will scan all listed files at cmake-time for such included moc files and if it finds them cause a rule to be generated to run moc at build time on the accompanying header file foo.h. If a source file has the SKIP_AUTOMOC property set it will be ignored by this macro. If the <tgt> is specified, the INTERFACE_INCLUDE_DIRECTORIES and INTERFACE_COMPILE_DEFINITIONS from the <tgt> are passed to moc. function QT4_USE_MODULES( target [link_type] modules...) This function is obsolete. Use target_link_libraries with IMPORTED targets instead. Make <target> use the <modules> from Qt. Using a Qt module means to link to the library, add the relevant include directories for the module, and add the relevant compiler defines for using the module. Modules are roughly equivalent to components of Qt4, so usage would be something like: qt4_use_modules(myexe Core Gui Declarative) to use QtCore, QtGui and QtDeclarative. The optional <link_type> argument can be specified as either LINK_PUBLIC or LINK_PRIVATE to specify the same argument to the target_link_libraries call. IMPORTED Targets A particular Qt library may be used by using the corresponding IMPORTED target with the target_link_libraries() command: target_link_libraries(myexe Qt4::QtGui Qt4::QtXml) Using a target in this way causes :cmake(1)` to use the appropriate include directories and compile definitions for the target when compiling myexe. Targets are aware of their dependencies, so for example it is not necessary to list Qt4::QtCore if another Qt library is listed, and it is not necessary to list Qt4::QtGui if Qt4::QtDeclarative is listed. Targets may be tested for existence in the usual way with the if(TARGET) command. The Qt toolkit may contain both debug and release libraries. cmake(1) will choose the appropriate version based on the build configuration. Qt4::QtCore The QtCore target Qt4::QtGui The QtGui target Qt4::Qt3Support The Qt3Support target Qt4::QtAssistant The QtAssistant target Qt4::QtAssistantClient The QtAssistantClient target Qt4::QAxContainer The QAxContainer target (Windows only) Qt4::QAxServer The QAxServer target (Windows only) Qt4::QtDBus The QtDBus target Qt4::QtDesigner The QtDesigner target Qt4::QtDesignerComponents The QtDesignerComponents target Qt4::QtHelp The QtHelp target Qt4::QtMotif The QtMotif target Qt4::QtMultimedia The QtMultimedia target Qt4::QtNetwork The QtNetwork target Qt4::QtNsPLugin The QtNsPLugin target Qt4::QtOpenGL The QtOpenGL target Qt4::QtScript The QtScript target Qt4::QtScriptTools The QtScriptTools target Qt4::QtSql The QtSql target Qt4::QtSvg The QtSvg target Qt4::QtTest The QtTest target Qt4::QtUiTools The QtUiTools target Qt4::QtWebKit The QtWebKit target Qt4::QtXml The QtXml target Qt4::QtXmlPatterns The QtXmlPatterns target Qt4::phonon The phonon target Result Variables Below is a detailed list of variables that FindQt4.cmake sets. Qt4_FOUND If false, don't try to use Qt 4. QT_FOUND If false, don't try to use Qt. This variable is for compatibility only. QT4_FOUND If false, don't try to use Qt 4. This variable is for compatibility only. QT_VERSION_MAJOR The major version of Qt found. QT_VERSION_MINOR The minor version of Qt found. QT_VERSION_PATCH The patch version of Qt found. FindQt Searches for all installed versions of Qt. This should only be used if your project can work with multiple versions of Qt. If not, you should just directly use FindQt4 or FindQt3. If multiple versions of Qt are found on the machine, then The user must set the option DESIRED_QT_VERSION to the version they want to use. If only one version of qt is found on the machine, then the DESIRED_QT_VERSION is set to that version and the matching FindQt3 or FindQt4 module is included. Once the user sets DESIRED_QT_VERSION, then the FindQt3 or FindQt4 module is included. This module can only detect and switch between Qt versions 3 and 4. It cannot handle Qt5 or any later versions. QT_REQUIRED if this is set to TRUE then if CMake can not find Qt4 or Qt3 an error is raised and a message is sent to the user. DESIRED_QT_VERSION OPTION is created QT4_INSTALLED is set to TRUE if qt4 is found. QT3_INSTALLED is set to TRUE if qt3 is found. FindQuickTime Locate QuickTime This module defines QUICKTIME_LIBRARY QUICKTIME_FOUND, if false, do not try to link to gdal QUICKTIME_INCLUDE_DIR, where to find the headers $QUICKTIME_DIR is an environment variable that would correspond to the Created by Eric Wing. FindRTI Try to find M&S HLA RTI libraries This module finds if any HLA RTI is installed and locates the standard RTI include files and libraries. RTI is a simulation infrastructure standardized by IEEE and SISO. It has a well defined C++ API that assures that simulation applications are independent on a particular RTI implementation. http://en.wikipedia.org/wiki/Run-Time_Infrastructure_(simulation) This code sets the following variables: RTI_INCLUDE_DIR = the directory where RTI includes file are found RTI_LIBRARIES = The libraries to link against to use RTI RTI_DEFINITIONS = -DRTI_USES_STD_FSTREAM RTI_FOUND = Set to FALSE if any HLA RTI was not found Report problems to <@nongnu.org> FindRuby Find Ruby This module finds if Ruby is installed and determines where the include files and libraries are. Ruby 1.8, 1.9, 2.0 and 2.1 are supported. The minimum required version of Ruby can be specified using the standard syntax, e.g. find_package(Ruby 1.8) It also determines what the name of the library is. This code sets the following vari‐ ables: RUBY_EXECUTABLE full path to the ruby binary RUBY_INCLUDE_DIRS include dirs to be used when using the ruby library RUBY_LIBRARY full path to the ruby library RUBY_VERSION the version of ruby which was found, e.g. "1.8.7" RUBY_FOUND set to true if ruby ws found successfully Also: RUBY_INCLUDE_PATH same as RUBY_INCLUDE_DIRS, only provided for compatibility reasons, don't use it FindSDL_image Locate SDL_image library This module defines: SDL_IMAGE_LIBRARIES, the name of the library to link against SDL_IMAGE_INCLUDE_DIRS, where to find the headers SDL_IMAGE_FOUND, if false, do not try to link against SDL_IMAGE_VERSION_STRING - human-readable string containing the version of SDL_image For backward compatiblity the following variables are also set: SDLIMAGE_LIBRARY (same value as SDL_IMAGE_LIBRARIES) SDLIMAGE_INCLUDE_DIR (same value as SDL_IMAGE_INCLUDE_DIRS) SDLIMAGE_FOUND (same value as SDL_IMAGE_FOUND) $SDLDIR is an environment variable that would correspond to the Created by Eric Wing. This was influenced by the FindSDL.cmake module, but with modifica‐ tions to recognize OS X frameworks and additional Unix paths (FreeBSD, etc). FindSDL_mixer Locate SDL_mixer library This module defines: SDL_MIXER_LIBRARIES, the name of the library to link against SDL_MIXER_INCLUDE_DIRS, where to find the headers SDL_MIXER_FOUND, if false, do not try to link against SDL_MIXER_VERSION_STRING - human-readable string containing the version of SDL_mixer For backward compatiblity the following variables are also set: SDLMIXER_LIBRARY (same value as SDL_MIXER_LIBRARIES) SDLMIXER_INCLUDE_DIR (same value as SDL_MIXER_INCLUDE_DIRS) SDLMIXER_FOUND (same value as SDL_MIXER_FOUND) $SDLDIR is an environment variable that would correspond to the Created by Eric Wing. This was influenced by the FindSDL.cmake module, but with modifica‐ tions to recognize OS X frameworks and additional Unix paths (FreeBSD, etc). FindSDL_net Locate SDL_net library This module defines: SDL_NET_LIBRARIES, the name of the library to link against SDL_NET_INCLUDE_DIRS, where to find the headers SDL_NET_FOUND, if false, do not try to link against SDL_NET_VERSION_STRING - human-readable string containing the version of SDL_net For backward compatiblity the following variables are also set: SDLNET_LIBRARY (same value as SDL_NET_LIBRARIES) SDLNET_INCLUDE_DIR (same value as SDL_NET_INCLUDE_DIRS) SDLNET_FOUND (same value as SDL_NET_FOUND) $SDLDIR is an environment variable that would correspond to the Created by Eric Wing. This was influenced by the FindSDL.cmake module, but with modifica‐ tions to recognize OS X frameworks and additional Unix paths (FreeBSD, etc). FindSDL Locate SDL library This module defines SDL_LIBRARY, the name of the library to link against SDL_FOUND, if false, do not try to link to SDL SDL_INCLUDE_DIR, where to find SDL.h SDL_VERSION_STRING, human-readable string containing the version of SDL This module responds to the flag: SDL_BUILDING_LIBRARY If this is defined, then no SDL_main will be linked in because only applications need main(). Otherwise, it is assumed you are building an application and this module will attempt to locate and set the proper link flags as part of the returned SDL_LIBRARY variable. Don't forget to include SDLmain.h and SDLmain.m your project for the OS X framework based version. (Other versions link to -lSDLmain which this module will try to find on your behalf.) Also for OS X, this module will automatically add the -framework Cocoa on your behalf. Additional Note: If you see an empty SDL_LIBRARY_TEMP in your configuration and no SDL_LIBRARY, it means CMake did not find your SDL library (SDL.dll, libsdl.so, SDL.frame‐ work, etc). Set SDL_LIBRARY_TEMP to point to your SDL library, and configure again. Sim‐ ilarly, if you see an empty SDLMAIN_LIBRARY, you should set this value as appropriate. These values are used to generate the final SDL_LIBRARY variable, but when these values are unset, SDL_LIBRARY does not get created. $SDLDIR is an environment variable that would correspond to the Modified by Eric Wing. Added code to assist with automated building by using environmen‐ tal variables and providing a more controlled/consistent search behavior. Added new modi‐ fications to recognize OS X frameworks and additional Unix paths (FreeBSD, etc). Also corrected the header search path to follow "proper" SDL guidelines. Added a search for SDLmain which is needed by some platforms. Added a search for threads which is needed by some platforms. Added needed compile switches for MinGW. On OSX, this will prefer the Framework version (if found) over others. People will have to manually change the cache values of SDL_LIBRARY to override this selection or set the CMake environment CMAKE_INCLUDE_PATH to modify the search paths. Note that the header path has changed from SDL/SDL.h to just SDL.h This needed to change because "proper" SDL convention is #include "SDL.h", not <SDL/SDL.h>. This is done for portability reasons because not all systems place things in SDL/ (see FreeBSD). FindSDL_sound Locates the SDL_sound library This module depends on SDL being found and must be called AFTER FindSDL.cmake is called. This module defines SDL_SOUND_INCLUDE_DIR, where to find SDL_sound.h SDL_SOUND_FOUND, if false, do not try to link to SDL_sound SDL_SOUND_LIBRARIES, this contains the list of libraries that you need to link against. This is a read-only variable and is marked INTERNAL. SDL_SOUND_EXTRAS, this is an optional variable for you to add your own flags to SDL_SOUND_LIBRARIES. This is prepended to SDL_SOUND_LIBRARIES. This is available mostly for cases this module failed to anticipate for and you must add additional flags. This is marked as ADVANCED. SDL_SOUND_VERSION_STRING, human-readable string containing the version of SDL_sound This module also defines (but you shouldn't need to use directly) SDL_SOUND_LIBRARY, the name of just the SDL_sound library you would link against. Use SDL_SOUND_LIBRARIES for you link instructions and not this one. And might define the following as needed MIKMOD_LIBRARY MODPLUG_LIBRARY OGG_LIBRARY VORBIS_LIBRARY SMPEG_LIBRARY FLAC_LIBRARY SPEEX_LIBRARY Typically, you should not use these variables directly, and you should use SDL_SOUND_LIBRARIES which contains SDL_SOUND_LIBRARY and the other audio libraries (if needed) to successfully compile on your system. Created by Eric Wing. This module is a bit more complicated than the other FindSDL* fam‐ ily modules. The reason is that SDL_sound can be compiled in a large variety of different ways which are independent of platform. SDL_sound may dynamically link against other 3rd party libraries to get additional codec support, such as Ogg Vorbis, SMPEG, ModPlug, Mik‐ Mod, FLAC, Speex, and potentially others. Under some circumstances which I don't fully understand, there seems to be a requirement that dependent libraries of libraries you use must also be explicitly linked against in order to successfully compile. SDL_sound does not currently have any system in place to know how it was compiled. So this CMake module does the hard work in trying to discover which 3rd party libraries are required for build‐ ing (if any). This module uses a brute force approach to create a test program that uses SDL_sound, and then tries to build it. If the build fails, it parses the error output for known symbol names to figure out which libraries are needed. Responds to the $SDLDIR and $SDLSOUNDDIR environmental variable that would correspond to the ./configure --prefix=$SDLDIR used in building SDL. On OSX, this will prefer the Framework version (if found) over others. People will have to manually change the cache values of SDL_LIBRARY to override this selectionor set the CMake environment CMAKE_INCLUDE_PATH to modify the search paths. FindSDL_ttf Locate SDL_ttf library This module defines: SDL_TTF_LIBRARIES, the name of the library to link against SDL_TTF_INCLUDE_DIRS, where to find the headers SDL_TTF_FOUND, if false, do not try to link against SDL_TTF_VERSION_STRING - human-readable string containing the version of SDL_ttf For backward compatiblity the following variables are also set: SDLTTF_LIBRARY (same value as SDL_TTF_LIBRARIES) SDLTTF_INCLUDE_DIR (same value as SDL_TTF_INCLUDE_DIRS) SDLTTF_FOUND (same value as SDL_TTF_FOUND) $SDLDIR is an environment variable that would correspond to the Created by Eric Wing. This was influenced by the FindSDL.cmake module, but with modifica‐ tions to recognize OS X frameworks and additional Unix paths (FreeBSD, etc). FindSelfPackers Find upx This module looks for some executable packers (i.e. software that compress executables or shared libs into on-the-fly self-extracting executables or shared libs. Examples: UPX: http://wildsau.idv.uni-linz.ac.at/mfx/upx.html FindSquish -- Typical Use This module can be used to find Squish. Currently Squish versions 3 and 4 are supported. SQUISH_FOUND If false, don't try to use Squish SQUISH_VERSION The full version of Squish found SQUISH_VERSION_MAJOR The major version of Squish found SQUISH_VERSION_MINOR The minor version of Squish found SQUISH_VERSION_PATCH The patch version of Squish found SQUISH_INSTALL_DIR The Squish installation directory (containing bin, lib, etc) SQUISH_SERVER_EXECUTABLE The squishserver executable SQUISH_CLIENT_EXECUTABLE The squishrunner executable SQUISH_INSTALL_DIR_FOUND Was the install directory found? SQUISH_SERVER_EXECUTABLE_FOUND Was the server executable found? SQUISH_CLIENT_EXECUTABLE_FOUND Was the client executable found? It provides the function squish_v4_add_test() for adding a squish test to cmake using Squish 4.x: squish_v4_add_test(cmakeTestName AUT targetName SUITE suiteName TEST squishTestName [SETTINGSGROUP group] [PRE_COMMAND command] [POST_COMMAND command] ) The arguments have the following meaning: cmakeTestName this will be used as the first argument for add_test() AUT targetName the name of the cmake target which will be used as AUT, i.e. the executable which will be tested. SUITE suiteName this is either the full path to the squish suite, or just the last directory of the suite, i.e. the suite name. In this case the CMakeLists.txt which calls squish_add_test() must be located in the parent directory of the suite directory. TEST squishTestName the name of the squish test, i.e. the name of the subdirectory of the test inside the suite directory. SETTINGSGROUP group if specified, the given settings group will be used for executing the test. If not specified, the groupname will be "CTest_<username>" PRE_COMMAND command if specified, the given command will be executed before starting the squish test. POST_COMMAND command same as PRE_COMMAND, but after the squish test has been executed. enable_testing() find_package(Squish 4.0) if (SQUISH_FOUND) squish_v4_add_test(myTestName AUT myApp SUITE ${CMAKE_SOURCE_DIR}/tests/mySuite TEST someSquishTest SETTINGSGROUP myGroup ) endif () For users of Squish version 3.x the macro squish_v3_add_test() is provided: squish_v3_add_test(testName applicationUnderTest testCase envVars testWrapper) Use this macro to add a test using Squish 3.x. enable_testing() find_package(Squish) if (SQUISH_FOUND) squish_v3_add_test(myTestName myApplication testCase envVars testWrapper) endif () macro SQUISH_ADD_TEST(testName applicationUnderTest testCase envVars testWrapper) This is deprecated. Use SQUISH_V3_ADD_TEST() if you are using Squish 3.x instead. FindSubversion Extract information from a subversion working copy The module defines the following variables: Subversion_SVN_EXECUTABLE - path to svn command line client Subversion_VERSION_SVN - version of svn command line client Subversion_FOUND - true if the command line client was found SUBVERSION_FOUND - same as Subversion_FOUND, set for compatiblity reasons The minimum required version of Subversion can be specified using the standard syntax, e.g. find_package(Subversion 1.4) If the command line client executable is found two macros are defined: Subversion_WC_INFO(<dir> <var-prefix>) Subversion_WC_LOG(<dir> <var-prefix>) Subversion_WC_INFO extracts information of a subversion working copy at a given location. This macro defines the following variables: <var-prefix>_WC_URL - url of the repository (at <dir>) <var-prefix>_WC_ROOT - root url of the repository <var-prefix>_WC_REVISION - current revision <var-prefix>_WC_LAST_CHANGED_AUTHOR - author of last commit <var-prefix>_WC_LAST_CHANGED_DATE - date of last commit <var-prefix>_WC_LAST_CHANGED_REV - revision of last commit <var-prefix>_WC_INFO - output of command `svn info <dir>' Subversion_WC_LOG retrieves the log message of the base revision of a subversion working copy at a given location. This macro defines the variable: <var-prefix>_LAST_CHANGED_LOG - last log of base revision Example usage: find_package(Subversion) if(SUBVERSION_FOUND) Subversion_WC_INFO(${PROJECT_SOURCE_DIR} Project) message("Current revision is ${Project_WC_REVISION}") Subversion_WC_LOG(${PROJECT_SOURCE_DIR} Project) message("Last changed log is ${Project_LAST_CHANGED_LOG}") endif() FindSWIG Find SWIG This module finds an installed SWIG. It sets the following variables: SWIG_FOUND - set to true if SWIG is found SWIG_DIR - the directory where swig is installed SWIG_EXECUTABLE - the path to the swig executable SWIG_VERSION - the version number of the swig executable The minimum required version of SWIG can be specified using the standard syntax, e.g. find_package(SWIG 1.1) All information is collected from the SWIG_EXECUTABLE so the version to be found can be changed from the command line by means of setting SWIG_EXECUTABLE FindTCL TK_INTERNAL_PATH was removed. This module finds if Tcl is installed and determines where the include files and libraries are. It also determines what the name of the library is. This code sets the following variables: TCL_FOUND = Tcl was found TK_FOUND = Tk was found TCLTK_FOUND = Tcl and Tk were found TCL_LIBRARY = path to Tcl library (tcl tcl80) TCL_INCLUDE_PATH = path to where tcl.h can be found TCL_TCLSH = path to tclsh binary (tcl tcl80) TK_LIBRARY = path to Tk library (tk tk80 etc) TK_INCLUDE_PATH = path to where tk.h can be found TK_WISH = full path to the wish executable In an effort to remove some clutter and clear up some issues for people who are not neces‐ sarily Tcl/Tk gurus/developpers, some variables were moved or removed. Changes compared to CMake 2.4 are: => they were only useful for people writing Tcl/Tk extensions. => these libs are not packaged by default with Tcl/Tk distributions. Even when Tcl/Tk is built from source, several flavors of debug libs are created and there is no real reason to pick a single one specifically (say, amongst tcl84g, tcl84gs, or tcl84sgx). Let's leave that choice to the user by allowing him to assign TCL_LIBRARY to any Tcl library, debug or not. => this ended up being only a Win32 variable, and there is a lot of confusion regarding the location of this file in an installed Tcl/Tk tree anyway (see 8.5 for example). If you need the internal path at this point it is safer you ask directly where the *source* tree is and dig from there. FindTclsh Find tclsh This module finds if TCL is installed and determines where the include files and libraries are. It also determines what the name of the library is. This code sets the following variables: TCLSH_FOUND = TRUE if tclsh has been found TCL_TCLSH = the path to the tclsh executable In cygwin, look for the cygwin version first. Don't look for it later to avoid finding the cygwin version on a Win32 build. FindTclStub TCL_STUB_LIBRARY_DEBUG and TK_STUB_LIBRARY_DEBUG were removed. This module finds Tcl stub libraries. It first finds Tcl include files and libraries by calling FindTCL.cmake. How to Use the Tcl Stubs Library: http://tcl.activestate.com/doc/howto/stubs.html Using Stub Libraries: http://safari.oreilly.com/0130385603/ch48lev1sec3 This code sets the following variables: TCL_STUB_LIBRARY = path to Tcl stub library TK_STUB_LIBRARY = path to Tk stub library TTK_STUB_LIBRARY = path to ttk stub library In an effort to remove some clutter and clear up some issues for people who are not neces‐ sarily Tcl/Tk gurus/developpers, some variables were moved or removed. Changes compared to CMake 2.4 are: => these libs are not packaged by default with Tcl/Tk distributions. Even when Tcl/Tk is built from source, several flavors of debug libs are created and there is no real reason to pick a single one specifically (say, amongst tclstub84g, tclstub84gs, or tclstub84sgx). Let's leave that choice to the user by allowing him to assign TCL_STUB_LIBRARY to any Tcl library, debug or not. FindThreads This module determines the thread library of the system. The following variables are set CMAKE_THREAD_LIBS_INIT - the thread library CMAKE_USE_SPROC_INIT - are we using sproc? CMAKE_USE_WIN32_THREADS_INIT - using WIN32 threads? CMAKE_USE_PTHREADS_INIT - are we using pthreads CMAKE_HP_PTHREADS_INIT - are we using hp pthreads The following import target is created Threads::Threads For systems with multiple thread libraries, caller can set CMAKE_THREAD_PREFER_PTHREAD If the use of the -pthread compiler and linker flag is prefered then the caller can set THREADS_PREFER_PTHREAD_FLAG Please note that the compiler flag can only be used with the imported target. Use of both the imported target as well as this switch is highly recommended for new code. FindTIFF Find the TIFF library (libtiff). Imported targets This module defines the following IMPORTED targets: TIFF::TIFF The TIFF library, if found. Result variables This module will set the following variables in your project: TIFF_FOUND true if the TIFF headers and libraries were found TIFF_INCLUDE_DIR the directory containing the TIFF headers TIFF_INCLUDE_DIRS the directory containing the TIFF headers TIFF_LIBRARIES TIFF libraries to be linked Cache variables The following cache variables may also be set: TIFF_INCLUDE_DIR the directory containing the TIFF headers TIFF_LIBRARY the path to the TIFF library FindUnixCommands Find Unix commands, including the ones from Cygwin This module looks for the Unix commands bash, cp, gzip, mv, rm, and tar and stores the result in the variables BASH, CP, GZIP, MV, RM, and TAR. FindVTK This module no longer exists. This module existed in versions of CMake prior to 3.1, but became only a thin wrapper around find_package(VTK NO_MODULE) to provide compatibility for projects using long-out‐ dated conventions. Now find_package(VTK) will search for VTKConfig.cmake directly. FindWget Find wget This module looks for wget. This module defines the following values: WGET_EXECUTABLE: the full path to the wget tool. WGET_FOUND: True if wget has been found. FindWish Find wish installation This module finds if TCL is installed and determines where the include files and libraries are. It also determines what the name of the library is. This code sets the following variables: TK_WISH = the path to the wish executable if UNIX is defined, then it will look for the cygwin version first FindwxWidgets Find a wxWidgets (a.k.a., wxWindows) installation. This module finds if wxWidgets is installed and selects a default configuration to use. wxWidgets is a modular library. To specify the modules that you will use, you need to name them as components to the package: find_package(wxWidgets COMPONENTS core base ...) There are two search branches: a windows style and a unix style. For windows, the follow‐ ing variables are searched for and set to defaults in case of multiple choices. Change them if the defaults are not desired (i.e., these are the only variables you should change to select a configuration): wxWidgets_ROOT_DIR - Base wxWidgets directory (e.g., C:/wxWidgets-2.6.3). wxWidgets_LIB_DIR - Path to wxWidgets libraries (e.g., C:/wxWidgets-2.6.3/lib/vc_lib). wxWidgets_CONFIGURATION - Configuration to use (e.g., msw, mswd, mswu, mswunivud, etc.) wxWidgets_EXCLUDE_COMMON_LIBRARIES - Set to TRUE to exclude linking of commonly required libs (e.g., png tiff jpeg zlib regex expat). For unix style it uses the wx-config utility. You can select between debug/release, uni‐ code/ansi, universal/non-universal, and static/shared in the QtDialog or ccmake interfaces by turning ON/OFF the following variables: wxWidgets_USE_DEBUG wxWidgets_USE_UNICODE wxWidgets_USE_UNIVERSAL wxWidgets_USE_STATIC There is also a wxWidgets_CONFIG_OPTIONS variable for all other options that need to be passed to the wx-config utility. For example, to use the base toolkit found in the /usr/local path, set the variable (before calling the FIND_PACKAGE command) as such: set(wxWidgets_CONFIG_OPTIONS --toolkit=base --prefix=/usr) The following are set after the configuration is done for both windows and unix style: wxWidgets_FOUND - Set to TRUE if wxWidgets was found. wxWidgets_INCLUDE_DIRS - Include directories for WIN32 i.e., where to find "wx/wx.h" and "wx/setup.h"; possibly empty for unices. wxWidgets_LIBRARIES - Path to the wxWidgets libraries. wxWidgets_LIBRARY_DIRS - compile time link dirs, useful for rpath on UNIX. Typically an empty string in WIN32 environment. wxWidgets_DEFINITIONS - Contains defines required to compile/link against WX, e.g. WXUSINGDLL wxWidgets_DEFINITIONS_DEBUG- Contains defines required to compile/link against WX debug builds, e.g. __WXDEBUG__ wxWidgets_CXX_FLAGS - Include dirs and compiler flags for unices, empty on WIN32. Essentially "`wx-config --cxxflags`". wxWidgets_USE_FILE - Convenience include file. Sample usage: # Note that for MinGW users the order of libs is important! find_package(wxWidgets COMPONENTS net gl core base) if(wxWidgets_FOUND) include(${wxWidgets_USE_FILE}) # and for each of your dependent executable/library targets: target_link_libraries(<YourTarget> ${wxWidgets_LIBRARIES}) endif() If wxWidgets is required (i.e., not an optional part): find_package(wxWidgets REQUIRED net gl core base) include(${wxWidgets_USE_FILE}) # and for each of your dependent executable/library targets: target_link_libraries(<YourTarget> ${wxWidgets_LIBRARIES}) FindwxWindows Find wxWindows (wxWidgets) installation This module finds if wxWindows/wxWidgets is installed and determines where the include files and libraries are. It also determines what the name of the library is. Please note this file is DEPRECATED and replaced by FindwxWidgets.cmake. This code sets the following variables: WXWINDOWS_FOUND = system has WxWindows WXWINDOWS_LIBRARIES = path to the wxWindows libraries on Unix/Linux with additional linker flags from "wx-config --libs" CMAKE_WXWINDOWS_CXX_FLAGS = Compiler flags for wxWindows, essentially "`wx-config --cxxflags`" on Linux WXWINDOWS_INCLUDE_DIR = where to find "wx/wx.h" and "wx/setup.h" WXWINDOWS_LINK_DIRECTORIES = link directories, useful for rpath on Unix WXWINDOWS_DEFINITIONS = extra defines OPTIONS If you need OpenGL support please set(WXWINDOWS_USE_GL 1) in your CMakeLists.txt before you include this file. HAVE_ISYSTEM - true required to replace -I by -isystem on g++ For convenience include Use_wxWindows.cmake in your project's CMakeLists.txt using include(${CMAKE_CURRENT_LIST_DIR}/Use_wxWindows.cmake). USAGE set(WXWINDOWS_USE_GL 1) find_package(wxWindows) NOTES wxWidgets 2.6.x is supported for monolithic builds e.g. compiled in wx/build/msw dir as: nmake -f makefile.vc BUILD=debug SHARED=0 USE_OPENGL=1 MONOLITHIC=1 DEPRECATED CMAKE_WX_CAN_COMPILE WXWINDOWS_LIBRARY CMAKE_WX_CXX_FLAGS WXWINDOWS_INCLUDE_PATH AUTHOR Jan Woetzel <http://www.mip.informatik.uni-kiel.de/~jw> (07/2003-01/2006) FindXCTest Functions to help creating and executing XCTest bundles.

ZLIB_VERSION_STRING - The version of zlib found (x.y.z) ZLIB_VERSION_MAJOR - The major version of zlib ZLIB_VERSION_MINOR - The minor version of zlib ZLIB_VERSION_PATCH - The patch version of zlib ZLIB_VERSION_TWEAK - The tweak version of zlib Backward Compatibility The following variable are provided for backward compatibility ZLIB_MAJOR_VERSION - The major version of zlib ZLIB_MINOR_VERSION - The minor version of zlib ZLIB_PATCH_VERSION - The patch version of zlib Hints A user may set ZLIB_ROOT to a zlib installation root to tell this module where to look. FortranCInterface Fortran/C Interface Detection This module automatically detects the API by which C and Fortran languages interact. Variables indicate if the mangling is found: FortranCInterface_GLOBAL_FOUND = Global subroutines and functions FortranCInterface_MODULE_FOUND = Module subroutines and functions (declared by "MODULE PROCEDURE") A function is provided to generate a C header file containing macros to mangle symbol names: FortranCInterface_HEADER(<file> [MACRO_NAMESPACE <macro-ns>] [SYMBOL_NAMESPACE <ns>] [SYMBOLS [<module>:]<function> ...]) It generates in <file> definitions of the following macros: #define FortranCInterface_GLOBAL (name,NAME) ... #define FortranCInterface_GLOBAL_(name,NAME) ... #define FortranCInterface_MODULE (mod,name, MOD,NAME) ... #define FortranCInterface_MODULE_(mod,name, MOD,NAME) ... These macros mangle four categories of Fortran symbols, respectively: - Global symbols without '_': call mysub() - Global symbols with '_' : call my_sub() - Module symbols without '_': use mymod; call mysub() - Module symbols with '_' : use mymod; call my_sub() If mangling for a category is not known, its macro is left undefined. All macros require raw names in both lower case and upper case. The MACRO_NAMESPACE option replaces the default "FortranCInterface" prefix with a given namespace "<macro-ns>". The SYMBOLS option lists symbols to mangle automatically with C preprocessor definitions: <function> ==> #define <ns><function> ... <module>:<function> ==> #define <ns><module>_<function> ... If the mangling for some symbol is not known then no preprocessor definition is created, and a warning is displayed. The SYMBOL_NAMESPACE option prefixes all preprocessor defini‐ tions generated by the SYMBOLS option with a given namespace "<ns>". Example usage: include(FortranCInterface) FortranCInterface_HEADER(FC.h MACRO_NAMESPACE "FC_") This creates a "FC.h" header that defines mangling macros FC_GLOBAL(), FC_GLOBAL_(), FC_MODULE(), and FC_MODULE_(). Example usage: include(FortranCInterface) FortranCInterface_HEADER(FCMangle.h MACRO_NAMESPACE "FC_" SYMBOL_NAMESPACE "FC_" SYMBOLS mysub mymod:my_sub) This creates a "FCMangle.h" header that defines the same FC_*() mangling macros as the previous example plus preprocessor symbols FC_mysub and FC_mymod_my_sub. Another function is provided to verify that the Fortran and C/C++ compilers work together: FortranCInterface_VERIFY([CXX] [QUIET]) It tests whether a simple test executable using Fortran and C (and C++ when the CXX option is given) compiles and links successfully. The result is stored in the cache entry For‐ tranCInterface_VERIFIED_C (or FortranCInterface_VERIFIED_CXX if CXX is given) as a bool‐ ean. If the check fails and QUIET is not given the function terminates with a FATAL_ERROR message describing the problem. The purpose of this check is to stop a build early for incompatible compiler combinations. The test is built in the Release configuration. FortranCInterface is aware of possible GLOBAL and MODULE manglings for many Fortran com‐ pilers, but it also provides an interface to specify new possible manglings. Set the variables FortranCInterface_GLOBAL_SYMBOLS FortranCInterface_MODULE_SYMBOLS before including FortranCInterface to specify manglings of the symbols "MySub", "My_Sub", "MyModule:MySub", and "My_Module:My_Sub". For example, the code: set(FortranCInterface_GLOBAL_SYMBOLS mysub_ my_sub__ MYSUB_) # ^^^^^ ^^^^^^ ^^^^^ set(FortranCInterface_MODULE_SYMBOLS __mymodule_MOD_mysub __my_module_MOD_my_sub) # ^^^^^^^^ ^^^^^ ^^^^^^^^^ ^^^^^^ include(FortranCInterface) tells FortranCInterface to try given GLOBAL and MODULE manglings. (The carets point at raw symbol names for clarity in this example but are not needed.) GenerateExportHeader Function for generation of export macros for libraries This module provides the function GENERATE_EXPORT_HEADER(). The GENERATE_EXPORT_HEADER function can be used to generate a file suitable for preproces‐ sor inclusion which contains EXPORT macros to be used in library classes: GENERATE_EXPORT_HEADER( LIBRARY_TARGET [BASE_NAME <base_name>] [EXPORT_MACRO_NAME <export_macro_name>] [EXPORT_FILE_NAME <export_file_name>] [DEPRECATED_MACRO_NAME <deprecated_macro_name>] [NO_EXPORT_MACRO_NAME <no_export_macro_name>] [STATIC_DEFINE <static_define>] [NO_DEPRECATED_MACRO_NAME <no_deprecated_macro_name>] [DEFINE_NO_DEPRECATED] [PREFIX_NAME <prefix_name>] ) The target properties CXX_VISIBILITY_PRESET and VISIBILITY_INLINES_HIDDEN can be used to add the appropriate compile flags for targets. See the documentation of those target properties, and the convenience variables CMAKE_CXX_VISIBILITY_PRESET and CMAKE_VISIBIL‐ ITY_INLINES_HIDDEN. By default GENERATE_EXPORT_HEADER() generates macro names in a file name determined by the name of the library. This means that in the simplest case, users of GenerateExportHeader will be equivalent to: set(CMAKE_CXX_VISIBILITY_PRESET hidden) set(CMAKE_VISIBILITY_INLINES_HIDDEN 1) add_library(somelib someclass.cpp) generate_export_header(somelib) install(TARGETS somelib DESTINATION ${LIBRARY_INSTALL_DIR}) install(FILES someclass.h ${PROJECT_BINARY_DIR}/somelib_export.h DESTINATION ${INCLUDE_INSTALL_DIR} ) And in the ABI header files: #include "somelib_export.h" class SOMELIB_EXPORT SomeClass { ... }; The CMake fragment will generate a file in the ${CMAKE_CURRENT_BINARY_DIR} called somelib_export.h containing the macros SOMELIB_EXPORT, SOMELIB_NO_EXPORT, SOMELIB_DEPRE‐ CATED, SOMELIB_DEPRECATED_EXPORT and SOMELIB_DEPRECATED_NO_EXPORT. The resulting file should be installed with other headers in the library. The BASE_NAME argument can be used to override the file name and the names used for the macros: add_library(somelib someclass.cpp) generate_export_header(somelib BASE_NAME other_name ) Generates a file called other_name_export.h containing the macros OTHER_NAME_EXPORT, OTHER_NAME_NO_EXPORT and OTHER_NAME_DEPRECATED etc. The BASE_NAME may be overridden by specifiying other options in the function. For exam‐ ple: add_library(somelib someclass.cpp) generate_export_header(somelib EXPORT_MACRO_NAME OTHER_NAME_EXPORT ) creates the macro OTHER_NAME_EXPORT instead of SOMELIB_EXPORT, but other macros and the generated file name is as default: add_library(somelib someclass.cpp) generate_export_header(somelib DEPRECATED_MACRO_NAME KDE_DEPRECATED ) creates the macro KDE_DEPRECATED instead of SOMELIB_DEPRECATED. If LIBRARY_TARGET is a static library, macros are defined without values. If the same sources are used to create both a shared and a static library, the uppercased symbol ${BASE_NAME}_STATIC_DEFINE should be used when building the static library: add_library(shared_variant SHARED ${lib_SRCS}) add_library(static_variant ${lib_SRCS}) generate_export_header(shared_variant BASE_NAME libshared_and_static) set_target_properties(static_variant PROPERTIES COMPILE_FLAGS -DLIBSHARED_AND_STATIC_STATIC_DEFINE) This will cause the export macros to expand to nothing when building the static library. If DEFINE_NO_DEPRECATED is specified, then a macro ${BASE_NAME}_NO_DEPRECATED will be defined This macro can be used to remove deprecated code from preprocessor output: option(EXCLUDE_DEPRECATED "Exclude deprecated parts of the library" FALSE) if (EXCLUDE_DEPRECATED) set(NO_BUILD_DEPRECATED DEFINE_NO_DEPRECATED) endif() generate_export_header(somelib ${NO_BUILD_DEPRECATED}) And then in somelib: class SOMELIB_EXPORT SomeClass { public: #ifndef SOMELIB_NO_DEPRECATED SOMELIB_DEPRECATED void oldMethod(); #endif }; #ifndef SOMELIB_NO_DEPRECATED void SomeClass::oldMethod() { } #endif If PREFIX_NAME is specified, the argument will be used as a prefix to all generated macros. For example: generate_export_header(somelib PREFIX_NAME VTK_) Generates the macros VTK_SOMELIB_EXPORT etc. ADD_COMPILER_EXPORT_FLAGS( [<output_variable>] ) The ADD_COMPILER_EXPORT_FLAGS function adds -fvisibility=hidden to CMAKE_CXX_FLAGS if sup‐ ported, and is a no-op on Windows which does not need extra compiler flags for exporting support. You may optionally pass a single argument to ADD_COMPILER_EXPORT_FLAGS that will be populated with the CXX_FLAGS required to enable visibility support for the com‐ piler/architecture in use. This function is deprecated. Set the target properties CXX_VISIBILITY_PRESET and VISIBIL‐ ITY_INLINES_HIDDEN instead. GetPrerequisites Functions to analyze and list executable file prerequisites. This module provides functions to list the .dll, .dylib or .so files that an executable or shared library file depends on. (Its prerequisites.) It uses various tools to obtain the list of required shared library files: dumpbin (Windows) objdump (MinGW on Windows) ldd (Linux/Unix) otool (Mac OSX) The following functions are provided by this module: get_prerequisites list_prerequisites list_prerequisites_by_glob gp_append_unique is_file_executable gp_item_default_embedded_path (projects can override with gp_item_default_embedded_path_override) gp_resolve_item (projects can override with gp_resolve_item_override) gp_resolved_file_type (projects can override with gp_resolved_file_type_override) gp_file_type Requires CMake 2.6 or greater because it uses function, break, return and PARENT_SCOPE. GET_PREREQUISITES(<target> <prerequisites_var> <exclude_system> <recurse> <exepath> <dirs> [<rpaths>]) Get the list of shared library files required by <target>. The list in the variable named <prerequisites_var> should be empty on first entry to this function. On exit, <prerequi‐ sites_var> will contain the list of required shared library files. <target> is the full path to an executable file. <prerequisites_var> is the name of a CMake variable to contain the results. <exclude_system> must be 0 or 1 indicating whether to include or exclude "system" prerequisites. If <recurse> is set to 1 all prerequisites will be found recursively, if set to 0 only direct prerequisites are listed. <exepath> is the path to the top level executable used for @executable_path replacment on the Mac. <dirs> is a list of paths where libraries might be found: these paths are searched first when a target without any path info is given. Then standard system locations are also searched: PATH, Framework locations, /usr/lib... LIST_PREREQUISITES(<target> [<recurse> [<exclude_system> [<verbose>]]]) Print a message listing the prerequisites of <target>. <target> is the name of a shared library or executable target or the full path to a shared library or executable file. If <recurse> is set to 1 all prerequisites will be found recursively, if set to 0 only direct prerequisites are listed. <exclude_system> must be 0 or 1 indicating whether to include or exclude "system" prerequisites. With <verbose> set to 0 only the full path names of the prerequisites are printed, set to 1 extra informatin will be displayed. LIST_PREREQUISITES_BY_GLOB(<glob_arg> <glob_exp>) Print the prerequisites of shared library and executable files matching a globbing pat‐ tern. <glob_arg> is GLOB or GLOB_RECURSE and <glob_exp> is a globbing expression used with "file(GLOB" or "file(GLOB_RECURSE" to retrieve a list of matching files. If a match‐ ing file is executable, its prerequisites are listed. Any additional (optional) arguments provided are passed along as the optional arguments to the list_prerequisites calls. GP_APPEND_UNIQUE(<list_var> <value>) Append <value> to the list variable <list_var> only if the value is not already in the list. IS_FILE_EXECUTABLE(<file> <result_var>) Return 1 in <result_var> if <file> is a binary executable, 0 otherwise. GP_ITEM_DEFAULT_EMBEDDED_PATH(<item> <default_embedded_path_var>) Return the path that others should refer to the item by when the item is embedded inside a bundle. Override on a per-project basis by providing a project-specific gp_item_default_embed‐ ded_path_override function. GP_RESOLVE_ITEM(<context> <item> <exepath> <dirs> <resolved_item_var> [<rpaths>]) Resolve an item into an existing full path file. Override on a per-project basis by providing a project-specific gp_resolve_item_override function. GP_RESOLVED_FILE_TYPE(<original_file> <file> <exepath> <dirs> <type_var> [<rpaths>]) Return the type of <file> with respect to <original_file>. String describing type of pre‐ requisite is returned in variable named <type_var>. Use <exepath> and <dirs> if necessary to resolve non-absolute <file> values -- but only for non-embedded items. Possible types are: system local embedded other Override on a per-project basis by providing a project-specific gp_resolved_file_type_override function. GP_FILE_TYPE(<original_file> <file> <type_var>) Return the type of <file> with respect to <original_file>. String describing type of pre‐ requisite is returned in variable named <type_var>. Possible types are: system local embedded other GNUInstallDirs Define GNU standard installation directories Provides install directory variables as defined by the GNU Coding Standards. Result Variables Inclusion of this module defines the following variables: CMAKE_INSTALL_<dir> Destination for files of a given type. This value may be passed to the DESTINATION options of install() commands for the corresponding file type. CMAKE_INSTALL_FULL_<dir> The absolute path generated from the corresponding CMAKE_INSTALL_<dir> value. If the value is not already an absolute path, an absolute path is constructed typically by prepending the value of the CMAKE_INSTALL_PREFIX variable. However, there are some special cases as documented below. where <dir> is one of: BINDIR user executables (bin) SBINDIR system admin executables (sbin) LIBEXECDIR program executables (libexec) SYSCONFDIR read-only single-machine data (etc) SHAREDSTATEDIR modifiable architecture-independent data (com) LOCALSTATEDIR modifiable single-machine data (var) LIBDIR object code libraries (lib or lib64 or lib/<multiarch-tuple> on Debian) INCLUDEDIR C header files (include) OLDINCLUDEDIR C header files for non-gcc (/usr/include) DATAROOTDIR read-only architecture-independent data root (share) DATADIR read-only architecture-independent data (DATAROOTDIR) INFODIR info documentation (DATAROOTDIR/info) LOCALEDIR locale-dependent data (DATAROOTDIR/locale) MANDIR man documentation (DATAROOTDIR/man) DOCDIR documentation root (DATAROOTDIR/doc/PROJECT_NAME) If the includer does not define a value the above-shown default will be used and the value will appear in the cache for editing by the user. Special Cases The following values of CMAKE_INSTALL_PREFIX are special: / For <dir> other than the SYSCONFDIR and LOCALSTATEDIR, the value of CMAKE_INSTALL_<dir> is prefixed with usr/ if it is not user-specified as an absolute path. For example, the INCLUDEDIR value include becomes usr/include. This is required by the GNU Coding Standards, which state: When building the complete GNU system, the prefix will be empty and /usr will be a symbolic link to /. /usr For <dir> equal to SYSCONFDIR or LOCALSTATEDIR, the CMAKE_INSTALL_FULL_<dir> is com‐ puted by prepending just / to the value of CMAKE_INSTALL_<dir> if it is not user-speci‐ fied as an absolute path. For example, the SYSCONFDIR value etc becomes /etc. This is required by the GNU Coding Standards. /opt/... For <dir> equal to SYSCONFDIR or LOCALSTATEDIR, the CMAKE_INSTALL_FULL_<dir> is com‐ puted by appending the prefix to the value of CMAKE_INSTALL_<dir> if it is not user-specified as an absolute path. For example, the SYSCONFDIR value etc becomes /etc/opt/.... This is defined by the Filesystem Hierarchy Standard. InstallRequiredSystemLibraries Include this module to search for compiler-provided system runtime libraries and add install rules for them. Some optional variables may be set prior to including the module to adjust behavior: CMAKE_INSTALL_SYSTEM_RUNTIME_LIBS Specify additional runtime libraries that may not be detected. After inclusion any detected libraries will be appended to this. CMAKE_INSTALL_SYSTEM_RUNTIME_LIBS_SKIP Set to TRUE to skip calling the install(PROGRAMS) command to allow the includer to specify its own install rule, using the value of CMAKE_INSTALL_SYSTEM_RUNTIME_LIBS to get the list of libraries. CMAKE_INSTALL_DEBUG_LIBRARIES Set to TRUE to install the debug runtime libraries when available with MSVC tools. CMAKE_INSTALL_DEBUG_LIBRARIES_ONLY Set to TRUE to install only the debug runtime libraries with MSVC tools even if the release runtime libraries are also available. CMAKE_INSTALL_MFC_LIBRARIES Set to TRUE to install the MSVC MFC runtime libraries. CMAKE_INSTALL_OPENMP_LIBRARIES Set to TRUE to install the MSVC OpenMP runtime libraries CMAKE_INSTALL_SYSTEM_RUNTIME_DESTINATION Specify the install(PROGRAMS) command DESTINATION option. If not specified, the default is bin on Windows and lib elsewhere. CMAKE_INSTALL_SYSTEM_RUNTIME_LIBS_NO_WARNINGS Set to TRUE to disable warnings about required library files that do not exist. (For example, Visual Studio Express editions may not provide the redistributable files.) CMAKE_INSTALL_SYSTEM_RUNTIME_COMPONENT Specify the install(PROGRAMS) command COMPONENT option. If not specified, no such option will be used. MacroAddFileDependencies MACRO_ADD_FILE_DEPENDENCIES(<_file> depend_files...) Using the macro MACRO_ADD_FILE_DEPENDENCIES() is discouraged. There are usually better ways to specify the correct dependencies. MACRO_ADD_FILE_DEPENDENCIES(<_file> depend_files...) is just a convenience wrapper around the OBJECT_DEPENDS source file property. You can just use set_property(SOURCE <file> APPEND PROPERTY OBJECT_DEPENDS depend_files) instead. ProcessorCount ProcessorCount(var) Determine the number of processors/cores and save value in ${var} Sets the variable named ${var} to the number of physical cores available on the machine if the information can be determined. Otherwise it is set to 0. Currently this functional‐ ity is implemented for AIX, cygwin, FreeBSD, HPUX, IRIX, Linux, Mac OS X, QNX, Sun and Windows. This function is guaranteed to return a positive integer (>=1) if it succeeds. It returns 0 if there's a problem determining the processor count. Example use, in a ctest -S dashboard script: include(ProcessorCount) ProcessorCount(N) if(NOT N EQUAL 0) set(CTEST_BUILD_FLAGS -j${N}) set(ctest_test_args ${ctest_test_args} PARALLEL_LEVEL ${N}) endif() This function is intended to offer an approximation of the value of the number of compute cores available on the current machine, such that you may use that value for parallel building and parallel testing. It is meant to help utilize as much of the machine as seems reasonable. Of course, knowledge of what else might be running on the machine simultaneously should be used when deciding whether to request a machine's full capacity all for yourself. SelectLibraryConfigurations select_library_configurations( basename ) This macro takes a library base name as an argument, and will choose good values for base‐ name_LIBRARY, basename_LIBRARIES, basename_LIBRARY_DEBUG, and basename_LIBRARY_RELEASE depending on what has been found and set. If only basename_LIBRARY_RELEASE is defined, basename_LIBRARY will be set to the release value, and basename_LIBRARY_DEBUG will be set to basename_LIBRARY_DEBUG-NOTFOUND. If only basename_LIBRARY_DEBUG is defined, then base‐ name_LIBRARY will take the debug value, and basename_LIBRARY_RELEASE will be set to base‐ name_LIBRARY_RELEASE-NOTFOUND. If the generator supports configuration types, then basename_LIBRARY and base‐ name_LIBRARIES will be set with debug and optimized flags specifying the library to be used for the given configuration. If no build type has been set or the generator in use does not support configuration types, then basename_LIBRARY and basename_LIBRARIES will take only the release value, or the debug value if the release one is not set. SquishTestScript This script launches a GUI test using Squish. You should not call the script directly; instead, you should access it via the SQUISH_ADD_TEST macro that is defined in Find‐ Squish.cmake. This script starts the Squish server, launches the test on the client, and finally stops the squish server. If any of these steps fail (including if the tests do not pass) then a fatal error is raised. TestBigEndian Define macro to determine endian type Check if the system is big endian or little endian TEST_BIG_ENDIAN(VARIABLE) VARIABLE - variable to store the result to TestCXXAcceptsFlag Deprecated. See CheckCXXCompilerFlag. Check if the CXX compiler accepts a flag. CHECK_CXX_ACCEPTS_FLAG(<flags> <variable>) <flags> the flags to try <variable> variable to store the result TestForANSIForScope Check for ANSI for scope support Check if the compiler restricts the scope of variables declared in a for-init-statement to the loop body. CMAKE_NO_ANSI_FOR_SCOPE - holds result TestForANSIStreamHeaders Test for compiler support of ANSI stream headers iostream, etc. check if the compiler supports the standard ANSI iostream header (without the .h) CMAKE_NO_ANSI_STREAM_HEADERS - defined by the results TestForSSTREAM Test for compiler support of ANSI sstream header check if the compiler supports the standard ANSI sstream header CMAKE_NO_ANSI_STRING_STREAM - defined by the results TestForSTDNamespace Test for std:: namespace support check if the compiler supports std:: on stl classes CMAKE_NO_STD_NAMESPACE - defined by the results UseEcos This module defines variables and macros required to build eCos application. This file contains the following macros: ECOS_ADD_INCLUDE_DIRECTORIES() - add the eCos include dirs ECOS_ADD_EXECUTABLE(name source1 ... sourceN ) - create an eCos executable ECOS_ADJUST_DIRECTORY(VAR source1 ... sourceN ) - adjusts the path of the source files and puts the result into VAR Macros for selecting the toolchain: ECOS_USE_ARM_ELF_TOOLS() - enable the ARM ELF toolchain for the directory where it is called ECOS_USE_I386_ELF_TOOLS() - enable the i386 ELF toolchain for the directory where it is called ECOS_USE_PPC_EABI_TOOLS() - enable the PowerPC toolchain for the directory where it is called It contains the following variables: ECOS_DEFINITIONS ECOSCONFIG_EXECUTABLE ECOS_CON‐ FIG_FILE - defaults to ecos.ecc, if your eCos configuration file has a different name, adjust this variable for internal use only: ECOS_ADD_TARGET_LIB UseJavaClassFilelist This script create a list of compiled Java class files to be added to a jar file. This avoids including cmake files which get created in the binary directory. UseJava Use Module for Java This file provides functions for Java. It is assumed that FindJava.cmake has already been loaded. See FindJava.cmake for information on how to load Java into your CMake project. add_jar(target_name [SOURCES] source1 [source2 ...] [resource1 ...] [INCLUDE_JARS jar1 [jar2 ...]] [ENTRY_POINT entry] [VERSION version] [OUTPUT_NAME name] [OUTPUT_DIR dir] ) This command creates a <target_name>.jar. It compiles the given source files (source) and adds the given resource files (resource) to the jar file. Source files can be java files or listing files (prefixed by '@'). If only resource files are given then just a jar file is created. The list of include jars are added to the classpath when compiling the java sources and also to the dependencies of the target. INCLUDE_JARS also accepts other tar‐ get names created by add_jar. For backwards compatibility, jar files listed as sources are ignored (as they have been since the first version of this module). The default OUTPUT_DIR can also be changed by setting the variable CMAKE_JAVA_TARGET_OUT‐ PUT_DIR. Additional instructions: To add compile flags to the target you can set these flags with the following variable: set(CMAKE_JAVA_COMPILE_FLAGS -nowarn) To add a path or a jar file to the class path you can do this with the CMAKE_JAVA_INCLUDE_PATH variable. set(CMAKE_JAVA_INCLUDE_PATH /usr/share/java/shibboleet.jar) To use a different output name for the target you can set it with: add_jar(foobar foobar.java OUTPUT_NAME shibboleet.jar) To use a different output directory than CMAKE_CURRENT_BINARY_DIR you can set it with: add_jar(foobar foobar.java OUTPUT_DIR ${PROJECT_BINARY_DIR}/bin) To define an entry point in your jar you can set it with the ENTRY_POINT named argument: add_jar(example ENTRY_POINT com/examples/MyProject/Main) To define a custom manifest for the jar, you can set it with the manifest named argument: add_jar(example MANIFEST /path/to/manifest) To add a VERSION to the target output name you can set it using the VERSION named argument to add_jar. This will create a jar file with the name shibboleet-1.0.0.jar and will create a symlink shibboleet.jar pointing to the jar with the version information. add_jar(shibboleet shibbotleet.java VERSION 1.2.0) If the target is a JNI library, utilize the following commands to create a JNI symbolic link: set(CMAKE_JNI_TARGET TRUE) add_jar(shibboleet shibbotleet.java VERSION 1.2.0) install_jar(shibboleet ${LIB_INSTALL_DIR}/shibboleet) install_jni_symlink(shibboleet ${JAVA_LIB_INSTALL_DIR}) If a single target needs to produce more than one jar from its java source code, to prevent the accumulation of duplicate class files in subsequent jars, set/reset CMAKE_JAR_CLASSES_PREFIX prior to calling the add_jar() function: set(CMAKE_JAR_CLASSES_PREFIX com/redhat/foo) add_jar(foo foo.java) set(CMAKE_JAR_CLASSES_PREFIX com/redhat/bar) add_jar(bar bar.java) Target Properties: The add_jar() functions sets some target properties. You can get these properties with the get_property(TARGET <target_name> PROPERTY <propery_name>) command. INSTALL_FILES The files which should be installed. This is used by install_jar(). JNI_SYMLINK The JNI symlink which should be installed. This is used by install_jni_symlink(). JAR_FILE The location of the jar file so that you can include it. CLASSDIR The directory where the class files can be found. For example to use them with javah. find_jar(<VAR> name | NAMES name1 [name2 ...] [PATHS path1 [path2 ... ENV var]] [VERSIONS version1 [version2]] [DOC "cache documentation string"] ) This command is used to find a full path to the named jar. A cache entry named by <VAR> is created to stor the result of this command. If the full path to a jar is found the result is stored in the variable and the search will not repeated unless the variable is cleared. If nothing is found, the result will be <VAR>-NOTFOUND, and the search will be attempted again next time find_jar is invoked with the same variable. The name of the full path to a file that is searched for is specified by the names listed after NAMES argument. Additional search locations can be specified after the PATHS argument. If you require special a version of a jar file you can specify it with the VERSIONS argument. The argument after DOC will be used for the documentation string in the cache. install_jar(target_name destination) install_jar(target_name DESTINATION destination [COMPONENT component]) This command installs the TARGET_NAME files to the given DESTINATION. It should be called in the same scope as add_jar() or it will fail. install_jni_symlink(target_name destination) install_jni_symlink(target_name DESTINATION destination [COMPONENT component]) This command installs the TARGET_NAME JNI symlinks to the given DESTINATION. It should be called in the same scope as add_jar() or it will fail. create_javadoc(<VAR> PACKAGES pkg1 [pkg2 ...] [SOURCEPATH <sourcepath>] [CLASSPATH <classpath>] [INSTALLPATH <install path>] [DOCTITLE "the documentation title"] [WINDOWTITLE "the title of the document"] [AUTHOR TRUE|FALSE] [USE TRUE|FALSE] [VERSION TRUE|FALSE] ) Create java documentation based on files or packages. For more details please read the javadoc manpage. There are two main signatures for create_javadoc. The first signature works with package names on a path with source files: Example: create_javadoc(my_example_doc PACKAGES com.exmaple.foo com.example.bar SOURCEPATH "${CMAKE_CURRENT_SOURCE_DIR}" CLASSPATH ${CMAKE_JAVA_INCLUDE_PATH} WINDOWTITLE "My example" DOCTITLE "<h1>My example</h1>" AUTHOR TRUE USE TRUE VERSION TRUE ) The second signature for create_javadoc works on a given list of files. create_javadoc(<VAR> FILES file1 [file2 ...] [CLASSPATH <classpath>] [INSTALLPATH <install path>] [DOCTITLE "the documentation title"] [WINDOWTITLE "the title of the document"] [AUTHOR TRUE|FALSE] [USE TRUE|FALSE] [VERSION TRUE|FALSE] ) Example: create_javadoc(my_example_doc FILES ${example_SRCS} CLASSPATH ${CMAKE_JAVA_INCLUDE_PATH} WINDOWTITLE "My example" DOCTITLE "<h1>My example</h1>" AUTHOR TRUE USE TRUE VERSION TRUE ) Both signatures share most of the options. These options are the same as what you can find in the javadoc manpage. Please look at the manpage for CLASSPATH, DOCTITLE, WIN‐ DOWTITLE, AUTHOR, USE and VERSION. The documentation will be by default installed to ${CMAKE_INSTALL_PREFIX}/share/javadoc/<VAR> if you don't set the INSTALLPATH. create_javah(TARGET <target> GENERATED_FILES <VAR> CLASSES <class>... [CLASSPATH <classpath>...] [DEPENDS <depend>...] [OUTPUT_NAME <path>|OUTPUT_DIR <path>] ) Create C header files from java classes. These files provide the connective glue that allow your Java and C code to interact. There are two main signatures for create_javah. The first signature returns generated files throught variable specified by GENERATED_FILES option: Example: Create_javah(GENERATED_FILES files_headers CLASSES org.cmake.HelloWorld CLASSPATH hello.jar ) The second signature for create_javah creates a target which encapsulates header files generation. Example: Create_javah(TARGET target_headers CLASSES org.cmake.HelloWorld CLASSPATH hello.jar ) Both signatures share same options. CLASSES <class>... Specifies Java classes used to generate headers. CLASSPATH <classpath>... Specifies various paths to look up classes. Here .class files, jar files or tar‐ gets created by command add_jar can be used. DEPENDS <depend>... Targets on which the javah target depends OUTPUT_NAME <path> Concatenates the resulting header files for all the classes listed by option CLASSES into <path>. Same behavior as option '-o' of javah tool. OUTPUT_DIR <path> Sets the directory where the header files will be generated. Same behavior as option '-d' of javah tool. If not specified, ${CMAKE_CURRENT_BINARY_DIR} is used as output directory. UseJavaSymlinks Helper script for UseJava.cmake UsePkgConfig Obsolete pkg-config module for CMake, use FindPkgConfig instead. This module defines the following macro: PKGCONFIG(package includedir libdir linkflags cflags) Calling PKGCONFIG will fill the desired information into the 4 given arguments, e.g. PKG‐ CONFIG(libart-2.0 LIBART_INCLUDE_DIR LIBART_LINK_DIR LIBART_LINK_FLAGS LIBART_CFLAGS) if pkg-config was NOT found or the specified software package doesn't exist, the variable will be empty when the function returns, otherwise they will contain the respective infor‐ mation UseSWIG Defines the following macros for use with SWIG: SWIG_ADD_MODULE(name language [ files ]) - Define swig module with given name and specified language SWIG_LINK_LIBRARIES(name [ libraries ]) - Link libraries to swig module Source files properties on module files can be set before the invocation of the SWIG_ADD_MODULE macro to specify special behavior of SWIG. The source file property CPLUSPLUS calls SWIG in c++ mode, e.g.: set_property(SOURCE mymod.i PROPERTY CPLUSPLUS ON) swig_add_module(mymod python mymod.i) The source file property SWIG_FLAGS adds custom flags to the SWIG executable. The source-file property SWIG_MODULE_NAME have to be provided to specify the actual import name of the module in the target language if it cannot be scanned automatically from source or different from the module file basename.: set_property(SOURCE mymod.i PROPERTY SWIG_MODULE_NAME mymod_realname) To get the name of the swig module target library, use: ${SWIG_MODULE_${name}_REAL_NAME}. Also some variables can be set to specify special behavior of SWIG. CMAKE_SWIG_FLAGS can be used to add special flags to all swig calls. Another special variable is CMAKE_SWIG_OUTDIR, it allows one to specify where to write all the swig generated module (swig -outdir option) The name-specific variable SWIG_MODULE_<name>_EXTRA_DEPS may be used to specify extra dependencies for the generated modules. If the source file generated by swig need some special flag you can use: set_source_files_properties( ${swig_generated_file_fullname} PROPERTIES COMPILE_FLAGS "-bla") UsewxWidgets Convenience include for using wxWidgets library. Determines if wxWidgets was FOUND and sets the appropriate libs, incdirs, flags, etc. INCLUDE_DIRECTORIES and LINK_DIRECTORIES are called. USAGE # Note that for MinGW users the order of libs is important! find_package(wxWidgets REQUIRED net gl core base) include(${wxWidgets_USE_FILE}) # and for each of your dependent executable/library targets: target_link_libraries(<YourTarget> ${wxWidgets_LIBRARIES}) DEPRECATED LINK_LIBRARIES is not called in favor of adding dependencies per target. AUTHOR Jan Woetzel <jw -at- mip.informatik.uni-kiel.de> Use_wxWindows This convenience include finds if wxWindows is installed and set the appropriate libs, incdirs, flags etc. author Jan Woetzel <jw -at- mip.informatik.uni-kiel.de> (07/2003) USAGE: just include Use_wxWindows.cmake in your projects CMakeLists.txt include( ${CMAKE_MODULE_PATH}/Use_wxWindows.cmake) if you are sure you need GL then set(WXWINDOWS_USE_GL 1) *before* you include this file. WriteBasicConfigVersionFile WRITE_BASIC_CONFIG_VERSION_FILE( filename [VERSION major.minor.patch] COMPATIBILITY (AnyNewerVersion|SameMajorVersion) ) Deprecated, see WRITE_BASIC_PACKAGE_VERSION_FILE(), it is identical. WriteCompilerDetectionHeader This module provides the function write_compiler_detection_header(). The WRITE_COMPILER_DETECTION_HEADER function can be used to generate a file suitable for preprocessor inclusion which contains macros to be used in source code: write_compiler_detection_header( FILE <file> PREFIX <prefix> [OUTPUT_FILES_VAR <output_files_var> OUTPUT_DIR <output_dir>] COMPILERS <compiler> [...] FEATURES <feature> [...] [VERSION <version>] [PROLOG <prolog>] [EPILOG <epilog>] ) The write_compiler_detection_header function generates the file <file> with macros which all have the prefix <prefix>. By default, all content is written directly to the <file>. The OUTPUT_FILES_VAR may be specified to cause the compiler-specific content to be written to separate files. The separate files are then available in the <output_files_var> and may be consumed by the caller for installation for example. The OUTPUT_DIR specifies a relative path from the main <file> to the compiler-specific files. For example: write_compiler_detection_header( FILE climbingstats_compiler_detection.h PREFIX ClimbingStats OUTPUT_FILES_VAR support_files OUTPUT_DIR compilers COMPILERS GNU Clang MSVC FEATURES cxx_variadic_templates ) install(FILES ${CMAKE_CURRENT_BINARY_DIR}/climbingstats_compiler_detection.h DESTINATION include ) install(FILES ${support_files} DESTINATION include/compilers ) VERSION may be used to specify the API version to be generated. Future versions of CMake may introduce alternative APIs. A given API is selected by any <version> value greater than or equal to the version of CMake that introduced the given API and less than the ver‐ sion of CMake that introduced its succeeding API. The value of the CMAKE_MINI‐ MUM_REQUIRED_VERSION variable is used if no explicit version is specified. (As of CMake version 3.5.1 there is only one API version.) PROLOG may be specified as text content to write at the start of the header. EPILOG may be specified as text content to write at the end of the header At least one <compiler> and one <feature> must be listed. Compilers which are known to CMake, but not specified are detected and a preprocessor #error is generated for them. A preprocessor macro matching <PREFIX>_COMPILER_IS_<compiler> is generated for each compiler known to CMake to contain the value 0 or 1. Possible compiler identifiers are documented with the CMAKE_<LANG>_COMPILER_ID variable. Available features in this version of CMake are listed in the CMAKE_C_KNOWN_FEATURES and CMAKE_CXX_KNOWN_FEATURES global properties. See the cmake-compile-features(7) manual for information on compile features. Feature Test Macros For each compiler, a preprocessor macro is generated matching <PREFIX>_COMPILER_IS_<com‐ piler> which has the content either 0 or 1, depending on the compiler in use. Preprocessor macros for compiler version components are generated matching <PREFIX>_COMPILER_VER‐ SION_MAJOR <PREFIX>_COMPILER_VERSION_MINOR and <PREFIX>_COMPILER_VERSION_PATCH containing decimal values for the corresponding compiler version components, if defined. A preprocessor test is generated based on the compiler version denoting whether each fea‐ ture is enabled. A preprocessor macro matching <PREFIX>_COMPILER_<FEATURE>, where <FEA‐ TURE> is the upper-case <feature> name, is generated to contain the value 0 or 1 depending on whether the compiler in use supports the feature: write_compiler_detection_header( FILE climbingstats_compiler_detection.h PREFIX ClimbingStats COMPILERS GNU Clang AppleClang MSVC FEATURES cxx_variadic_templates ) #if ClimbingStats_COMPILER_CXX_VARIADIC_TEMPLATES template<typename... T> void someInterface(T t...) { /* ... */ } #else // Compatibility versions template<typename T1> void someInterface(T1 t1) { /* ... */ } template<typename T1, typename T2> void someInterface(T1 t1, T2 t2) { /* ... */ } template<typename T1, typename T2, typename T3> void someInterface(T1 t1, T2 t2, T3 t3) { /* ... */ } #endif Symbol Macros Some additional symbol-defines are created for particular features for use as symbols which may be conditionally defined empty: class MyClass ClimbingStats_FINAL { ClimbingStats_CONSTEXPR int someInterface() { return 42; } }; The ClimbingStats_FINAL macro will expand to final if the compiler (and its flags) support the cxx_final feature, and the ClimbingStats_CONSTEXPR macro will expand to constexpr if cxx_constexpr is supported. The following features generate corresponding symbol defines: ┌──────────────────────┬──────────────────────────┬─────────────┐ │Feature │ Define │ Symbol │ ├──────────────────────┼──────────────────────────┼─────────────┤ │c_restrict │ <PREFIX>_RESTRICT │ restrict │ ├──────────────────────┼──────────────────────────┼─────────────┤ │cxx_constexpr │ <PREFIX>_CONSTEXPR │ constexpr │ └──────────────────────┴──────────────────────────┴─────────────┘ │cxx_deleted_functions │ <PREFIX>_DELETED_FUNC‐ │ = delete │ │ │ TION │ │ ├──────────────────────┼──────────────────────────┼─────────────┤ │cxx_extern_templates │ <PREFIX>_EXTERN_TEMPLATE │ extern │ ├──────────────────────┼──────────────────────────┼─────────────┤ │cxx_final │ <PREFIX>_FINAL │ final │ ├──────────────────────┼──────────────────────────┼─────────────┤ │cxx_noexcept │ <PREFIX>_NOEXCEPT │ noexcept │ ├──────────────────────┼──────────────────────────┼─────────────┤ │cxx_noexcept │ <PREFIX>_NOEX‐ │ noexcept(X) │ │ │ CEPT_EXPR(X) │ │ ├──────────────────────┼──────────────────────────┼─────────────┤ │cxx_override │ <PREFIX>_OVERRIDE │ override │ └──────────────────────┴──────────────────────────┴─────────────┘ Compatibility Implementation Macros Some features are suitable for wrapping in a macro with a backward compatibility implemen‐ tation if the compiler does not support the feature. When the cxx_static_assert feature is not provided by the compiler, a compatibility imple‐ mentation is available via the <PREFIX>_STATIC_ASSERT(COND) and <PRE‐ FIX>_STATIC_ASSERT_MSG(COND, MSG) function-like macros. The macros expand to static_assert where that compiler feature is available, and to a compatibility implementation otherwise. In the first form, the condition is stringified in the message field of static_assert. In the second form, the message MSG is passed to the message field of static_assert, or ignored if using the backward compatibility implementation. The cxx_attribute_deprecated feature provides a macro definition <PREFIX>_DEPRECATED, which expands to either the standard [[deprecated]] attribute or a compiler-specific deco‐ rator such as __attribute__((__deprecated__)) used by GNU compilers. The cxx_alignas feature provides a macro definition <PREFIX>_ALIGNAS which expands to either the standard alignas decorator or a compiler-specific decorator such as __attribute__ ((__aligned__)) used by GNU compilers. The cxx_alignof feature provides a macro definition <PREFIX>_ALIGNOF which expands to either the standard alignof decorator or a compiler-specific decorator such as __alignof__ used by GNU compilers. ┌─────────────────────────┬─────────────────────────┬────────────────┐ │Feature │ Define │ Symbol │ ├─────────────────────────┼─────────────────────────┼────────────────┤ │cxx_alignas │ <PREFIX>_ALIGNAS │ alignas │ ├─────────────────────────┼─────────────────────────┼────────────────┤ │cxx_alignof │ <PREFIX>_ALIGNOF │ alignof │ ├─────────────────────────┼─────────────────────────┼────────────────┤ │cxx_nullptr │ <PREFIX>_NULLPTR │ nullptr │ ├─────────────────────────┼─────────────────────────┼────────────────┤ │cxx_static_assert │ <PREFIX>_STATIC_ASSERT │ static_assert │ ├─────────────────────────┼─────────────────────────┼────────────────┤ │cxx_static_assert │ <PRE‐ │ static_assert │ │ │ FIX>_STATIC_ASSERT_MSG │ │ ├─────────────────────────┼─────────────────────────┼────────────────┤ │cxx_attribute_deprecated │ <PREFIX>_DEPRECATED │ [[deprecated]] │ ├─────────────────────────┼─────────────────────────┼────────────────┤ │cxx_attribute_deprecated │ <PREFIX>_DEPRECATED_MSG │ [[deprecated]] │ ├─────────────────────────┼─────────────────────────┼────────────────┤ │cxx_thread_local │ <PREFIX>_THREAD_LOCAL │ thread_local │ └─────────────────────────┴─────────────────────────┴────────────────┘ A use-case which arises with such deprecation macros is the deprecation of an entire library. In that case, all public API in the library may be decorated with the <PRE‐ FIX>_DEPRECATED macro. This results in very noisy build output when building the library itself, so the macro may be may be defined to empty in that case when building the depre‐ cated library: add_library(compat_support ${srcs}) target_compile_definitions(compat_support PRIVATE CompatSupport_DEPRECATED= )
