cmake--变量---目录

• CMAKE_BINARY_DIR : if you are building in-source, this is the same as CMAKE_SOURCE_DIR, otherwise this is the top level directory of your build tree

• CMAKE_COMMAND : this is the complete path of the cmake which runs currently (e.g. /usr/local/bin/cmake). Note that if you have custom commands that invoke cmake -E, it is very important to use CMAKE_COMMAND as the CMake executable, because CMake might not be on the system PATH.

• CMAKE_CURRENT_BINARY_DIR : if you are building in-source, this is the same as CMAKE_CURRENT_SOURCE_DIR, otherwise this is the directory where the compiled or generated files from the current CMakeLists.txt will go to.

• CMAKE_CURRENT_SOURCE_DIR : this is the directory where the currently processed CMakeLists.txt is located in

• CMAKE_CURRENT_LIST_FILE : this is the full path to the listfile currently being processed.

• CMAKE_CURRENT_LIST_DIR : (since 2.8.3) this is the directory of the listfile currently being processed.

• CMAKE_CURRENT_LIST_LINE : this is linenumber where the variable is used.

• CMAKE_FILES_DIRECTORY : the directory within the current binary directory that contains all the CMake generated files. Typically evaluates to "/CMakeFiles". Note the leading slash for the directory. Typically used with the current binary directory, i.e. ${CMAKE_CURRENT_BINARY_DIR}${CMAKE_FILES_DIRECTORY}

• CMAKE_MODULE_PATH : tell CMake to search first in directories listed in CMAKE_MODULE_PATH when you use FIND_PACKAGE() or INCLUDE() SET(CMAKE_MODULE_PATH ${PROJECT_SOURCE_DIR}/MyCMakeScripts) FIND_PACKAGE(HelloWorld)

• CMAKE_ROOT : this is the CMake installation directory

• CMAKE_SOURCE_DIR : this is the directory which contains the top-level CMakeLists.txt, i.e. the top level source directory

• PROJECT_NAME : the name of the project set by PROJECT() command.

• CMAKE_PROJECT_NAME : the name of the first project set by the PROJECT() command, i.e. the top level project.

• PROJECT_BINARY_DIR : contains the full path to the top level directory of your build tree

• PROJECT_SOURCE_DIR : contains the full path to the root of your project source directory, i.e. to the nearest directory where CMakeLists.txt contains the PROJECT() command
