VARIABLES THAT PROVIDE INFORMATION

variables defined by cmake, that give information about the project, and cmake

CMAKE_AR
    Name of archiving tool for static libraries. This specifies name of the program that creates archive or static libraries.

CMAKE_BINARY_DIR
    The path to the top level of the build tree. This is the full path to the top level of the current CMake build tree. For an in-source build, this would be the same as CMAKE_SOURCE_DIR.

CMAKE_BUILD_TOOL
    Tool used for the acutal build process. This variable is set to the program that will be needed to build the output of CMake. If the generator selected was Visual Studio 6, the CMAKE_MAKE_PROGRAM will be set to msdev, for Unix makefiles it will be set to make or gmake, and for Visual Studio 7 it set to devenv. For Nmake Makefiles the value is nmake. This can be useful for adding special flags and commands based on the final build environment.

CMAKE_CACHEFILE_DIR
    The directory with the CMakeCache.txt file. This is the full path to the directory that has the CMakeCache.txt file in it. This is the same as CMAKE_BINARY_DIR.

CMAKE_CACHE_MAJOR_VERSION
    Major version of CMake used to create the CMakeCache.txt file This is stores the major version of CMake used to write a CMake cache file. It is only different when a different version of CMake is run on a previously created cache file.

CMAKE_CACHE_MINOR_VERSION
    Minor version of CMake used to create the CMakeCache.txt file This is stores the minor version of CMake used to write a CMake cache file. It is only different when a different version of CMake is run on a previously created cache file.

CMAKE_CACHE_RELEASE_VERSION
    Release version of CMake used to create the CMakeCache.txt file This is stores the release version of CMake used to write a CMake cache file. It is only different when a different version of CMake is run on a previously created cache file.

CMAKE_CFG_INTDIR
    Build time configuration directory for project. This is a variable that is used to provide developers access to the intermediate directory used by Visual Studio IDE projects. For example, if building Debug all executables and libraries end up in a Debug directory. On UNIX systems this variable is set to ".". However, with Visual Studio this variable is set to $(IntDir). $(IntDir) is expanded by the IDE only. So this variable should only be used in custom commands that will be run during the build process. This variable should not be used directly in a CMake command. CMake has no way of knowing if Debug or Release will be picked by the IDE for a build type. If a program needs to know the directory it was built in, it can use CMAKE_INTDIR. CMAKE_INTDIR is a C/C++ preprocessor macro that is defined on the command line of the compiler. If it has a value, it will be the intermediate directory used to build the file. This way an executable or a library can find files that are located in the build directory.

CMAKE_COMMAND
    The full path to the cmake executable. This is the full path to the CMake executable cmake which is useful from custom commands that want to use the cmake -E option for portable system commands. (e.g. /usr/local/bin/cmake

CMAKE_CURRENT_BINARY_DIR
    The path to the binary directory currently being processed. This the full path to the build directory that is currently being processed by cmake. Each directory added by add_subdirectory will create a binary directory in the build tree, and as it is being processed this variable will be set. For in-source builds this is the current source directory being processed.

CMAKE_CURRENT_LIST_FILE
    Full path to the listfile currently being processed. As CMake processes the listfiles in your project this variable will always be set to the one currently being processed. See also CMAKE_PARENT_LIST_FILE.

    Size of a void pointer. This is set to the size of a pointer on the machine, and is determined by a try compile. If a 64 bit size is found, then the library search path is modified to look for 64 bit libraries first.

CMAKE_SKIP_RPATH
    If true, do not add run time path information. If this is set to TRUE, then the rpath information is not added to compiled executables. The defaultis to add rpath information if the platform supports it.This allows for easy running from the build tree.

CMAKE_SOURCE_DIR
    The path to the top level of the source tree. This is the full path to the top level of the current CMake source tree. For an in-source build, this would be the same as CMAKE_BINARY_DIR.

VARIABLES THAT CHANGE BEHAVIOR

BUILD_SHARED_LIBS
    Global flag to cause add_library to create shared libraries if on. If present and true, this will cause all libraries to be built shared unless the library was explicitly added as a static library. This variable is often added to projects as an OPTION so that each user of a project can decide if they want to build the project using shared or static libraries.

CMAKE_BACKWARDS_COMPATIBILITY
    Version of cmake required to build project From the point of view of backwards compatibility, this specifies what version of CMake should be supported. By default this value is the version number of CMake that you are running. You can set this to an older version of CMake to support deprecated commands of CMake in projects that were written to use older versions of CMake. This can be set by the user or set at the beginning of a CMakeLists file.

CMAKE_BUILD_TYPE
    Specifies the build type for make based generators. This specifies what build type will be built in this tree. Possible values are empty, Debug, Release, RelWithDebInfo and MinSizeRel. This variable is only supported for make based generators. If this variable is supported, then CMake will also provide initial values for the variables with the name CMAKE_C_FLAGS_[Debug|Release|RelWithDebInfo|MinSizeRel]. For example, if CMAKE_BUILD_TYPE is Debug, then CMAKE_C_FLAGS_DEBUG will be added to the CMAKE_C_FLAGS.

CMAKE_CONFIGURATION_TYPES
    Specifies the available build types. This specifies what build types will be available such as Debug, Release, RelWithDebInfo etc. This has reasonable defaults on most platforms. But can be extended to provide other build types. See also CMAKE_BUILD_TYPE.

CMAKE_FIND_LIBRARY_PREFIXES
    Prefixes to prepend when looking for libraries. This specifies what prefixes to add to library names when the find_library command looks for libraries. On UNIX systems this is typically lib, meaning that when trying to find the foo library it will look for libfoo.

CMAKE_FIND_LIBRARY_SUFFIXES
    Suffixes to append when looking for libraries. This specifies what suffixes to add to library names when the find_library command looks for libraries. On Windows systems this is typically .lib and .dll, meaning that when trying to find the foo library it will look for foo.dll etc.

CMAKE_INCLUDE_PATH
    Path used for searching by FIND_FILE() and FIND_PATH(). Specifies a path which will be used both by FIND_FILE() and FIND_PATH(). Both commands will check each of the contained directories for the existence of the file which is currently searched. By default it is empty, it is intended to be set by the project. See also CMAKE_SYSTEM_INCLUDE_PATH, CMAKE_PREFIX_PATH.

CMAKE_INSTALL_PREFIX
    Install directory used by install. If "make install" is invoked or INSTALL is built, this directory is pre-pended onto all install directories. This variable defaults to /usr/local on UNIX and c:/Program Files on Windows.

CMAKE_LIBRARY_PATH
    Path used for searching by FIND_LIBRARY(). Specifies a path which will be used by FIND_LIBRARY(). FIND_LIBRARY() will check each of the contained directories for the existence of the library which is currently searched. By default it is empty, it is intended to be set by the project. See also CMAKE_SYSTEM_LIBRARY_PATH, CMAKE_PREFIX_PATH.

CMAKE_MFC_FLAG
    Tell cmake to use MFC for an executable or dll. This can be set in a CMakeLists.txt file and will enable MFC in the application. It should be set to 1 for static the static MFC library, and 2 for the shared MFC library. This is used in visual studio 6 and 7 project files. The CMakeSetup dialog uses MFC and the CMakeLists.txt looks like this: ADD_DEFINITIONS(-D_AFXDLL) set(CMAKE_MFC_FLAG 2) add_executable(CMakeSetup WIN32 ${SRCS})

CMAKE_MODULE_PATH
    Path to look for cmake modules to load. Specifies a path to override the default seach path for CMake modules. For example include commands will look in this path first for modules to include.

CMAKE_NOT_USING_CONFIG_FLAGS
    Skip _BUILD_TYPE flags if true. This is an internal flag used by the generators in CMake to tell CMake to skip the _BUILD_TYPE flags.

CMAKE_PREFIX_PATH
    Path used for searching by FIND_XXX(), with appropriate suffixes added. Specifies a path which will be used by the FIND_XXX() commands. It contains the "base" directories, the FIND_XXX() commands append appropriate subdirectories to the base directories. So FIND_PROGRAM() adds /bin to each of the directories in the path, FIND_LIBRARY() appends /lib to each of the directories, and FIND_PATH() and FIND_FILE() append /include . By default it is empty, it is intended to be set by the project. See also CMAKE_SYSTEM_PREFIX_PATH, CMAKE_INCLUDE_PATH, CMAKE_LIBRARY_PATH, CMAKE_PROGRAM_PATH.

CMAKE_PROGRAM_PATH
    Path used for searching by FIND_PROGRAM(). Specifies a path which will be used by FIND_PROGRAM().

See also CMAKE_SYSTEM_PROGRAM_PATH, CMAKE_PREFIX_PATH.

CMAKE_SYSTEM_INCLUDE_PATH
    Path used for searching by FIND_FILE() and FIND_PATH(). Specifies a path which will be used both by FIND_FILE() and FIND_PATH(). Both commands will check each of the contained directories for the existence of the file which is currently searched. By default it contains the standard directories for the current system. It is NOT intended to be modified by the project, use CMAKE_INCLUDE_PATH for this. See also CMAKE_SYSTEM_PREFIX_PATH.

CMAKE_SYSTEM_LIBRARY_PATH
    Path used for searching by FIND_LIBRARY(). Specifies a path which will be used by FIND_LIBRARY(). FIND_LIBRARY() will check each of the contained directories for the existence of the library which is currently searched. By default it contains the standard directories for the current system. It is NOT intended to be modified by the project, use CMAKE_SYSTEM_LIBRARY_PATH for this. See also CMAKE_SYSTEM_PREFIX_PATH.

CMAKE_SYSTEM_PREFIX_PATH
    Path used for searching by FIND_XXX(), with appropriate suffixes added. Specifies a path which will be used by the FIND_XXX() commands. It contains the "base" directories, the FIND_XXX() commands append appropriate subdirectories to the base directories. So FIND_PROGRAM() adds /bin to each of the directories in the path, FIND_LIBRARY() appends /lib to each of the directories, and FIND_PATH() and FIND_FILE() append /include . By default this contains the standard directories for the current system. It is NOT intended to be modified by the project, use CMAKE_PREFIX_PATH for this. See also CMAKE_SYSTEM_INCLUDE_PATH, CMAKE_SYSTEM_LIBRARY_PATH, CMAKE_SYSTEM_PROGRAM_PATH.

CMAKE_SYSTEM_PROGRAM_PATH
    Path used for searching by FIND_PROGRAM(). Specifies a path which will be used by FIND_PROGRAM(). FIND_PROGRAM() will check each of the contained directories for the existence of the program which is currently searched. By default it contains the standard directories for the current system. It is NOT intended to be modified by the project, use CMAKE_PROGRAM_PATH for this. See also CMAKE_SYSTEM_PREFIX_PATH.

CMAKE_USER_MAKE_RULES_OVERRIDE
    Specify a file that can change the build rule variables. If this variable is set, it should to point to a CMakeLists.txt file that will be read in by CMake after all the system settings have been set, but before they have been used. This would allow you to override any variables that need to be changed for some special project.

VARIABLES THAT DESCRIBE THE SYSTEM

    True on windows systems, including win64. Set to true when the host system is Windows and on cygwin.

CMAKE_OBJECT_PATH_MAX
    Maximum object file full-path length allowed by native build tools. CMake computes for every source file an object file name that is unique to the source file and deterministic with respect to the full path to the source file. This allows multiple source files in a target to share the same name if they lie in different directories without rebuilding when one is added or removed. However, it can produce long full paths in a few cases, so CMake shortens the path using a hashing scheme when the full path to an object file exceeds a limit. CMake has a built-in limit for each platform that is sufficient for common tools, but some native tools may have a lower limit. This variable may be set to specify the limit explicitly. The value must be an integer no less than 128.

CMAKE_SYSTEM
    Name of system cmake is compiling for. This variable is the composite of CMAKE_SYSTEM_NAMEand CMAKE_SYSTEM_VERSION, like this ${CMAKE_SYSTEM_NAME}-${CMAKE_SYSTEM_VERSION}. If CMAKE_SYSTEM_VERSION is not set, then CMAKE_SYSTEM is the same as CMAKE_SYSTEM_NAME.

CMAKE_BUILD_WITH_INSTALL_RPATH
    Use the install path for the RPATH Normally CMake uses the build tree for the RPATH when building executables etc on systems that use RPATH. When the software is installed the executables etc are relinked by CMake to have the install RPATH. If this variable is set to true then the software is always built with the install path for the RPATH and does not need to be relinked when installed.

CMAKE_DEBUG_POSTFIX
    A postfix to add to targets when build as debug. This variable is used to initialize the DEBUG_POSTFIX property on all the targets. If set the postfix will be appended to any targets built when the configuration is Debug.

CMAKE_EXE_LINKER_FLAGS
    Linker flags used to create executables. Flags used by the linker when creating an executable.

CMAKE_EXE_LINKER_FLAGS_[CMAKE_BUILD_TYPE]
    Flag used when linking an executable. Same as CMAKE_C_FLAGS_* but used by the linker when creating executables.

CMAKE_Fortran_MODULE_DIRECTORY
    Fortran module output directory. This variable is used to initialize the Fortran_MODULE_DIRECTORY property on all the targets. See that target property for additional information.

CMAKE_INSTALL_RPATH_USE_LINK_PATH
    Add paths to linker search and installed rpath. CMAKE_INSTALL_RPATH_USE_LINK_PATH is a boolean that if set to true will append directories in the linker search path and outside the project to the INSTALL_RPATH.

CMAKE_LIBRARY_PATH_FLAG
    The flag used to add a library search path to a compiler. The flag used to specify a library directory to the compiler. On most compilers this is "-L".

CMAKE_LINK_DEF_FILE_FLAG
    Linker flag used to specify a .def file for dll creation. The flag used to add a .def file when creating a dll on Windows, this is only defined on Windows.

CMAKE_LINK_LIBRARY_FILE_FLAG
    Flag used to link a library specified by a path to its file. The flag used before a library file path is given to the linker. This is needed only on very few platforms.

CMAKE_LINK_LIBRARY_FLAG
    Flag used to link a library into an executable. The flag used to specify a library to link to an executable. On most compilers this is "-l".

CMAKE_RUNTIME_OUTPUT_DIRECTORY
    Where to put all the RUNTIME targets when built. This variable is used to initialize the RUNTIME_OUTPUT_DIRECTORY property on all the targets. See that target property for additional information.

CMAKE_SKIP_BUILD_RPATH
    Do not include RPATHs in the build tree. Normally CMake uses the build tree for the RPATH when building executables etc on systems that use RPATH. When the software is installed the executables etc are relinked by CMake to have the install RPATH. If this variable is set to true then the software is always built with no RPATH.

CMAKE_USE_RELATIVE_PATHS
    Use relative paths (May not work!). If this is set to TRUE, then the CMake will use relative paths between the source and binary tree. This option does not work for more complicated projects, and relative paths are used when possible. In general, it is not possible to move CMake generated makefiles to a different location regardless of the value of this variable.

EXECUTABLE_OUTPUT_PATH
    Old executable location variable. This variable should no longer be used as of CMake 2.6. Use the RUNTIME_OUTPUT_DIRECTORY target property instead. It will override this variable if it is set. If set, this is the directory where all executables built during the build process will be placed.

LIBRARY_OUTPUT_PATH
    Old library location variable. This variable should no longer be used as of CMake 2.6. Use the ARCHIVE_OUTPUT_DIRECTORY, LIBRARY_OUTPUT_DIRECTORY, and RUNTIME_OUTPUT_DIRECTORY target properties instead. They will override this variable if they are set. If set, this is the directory where all the libraries built during the build process will be placed.
