The source_dir specifies the +directory in which the source CMakeLists.txt and code files are +located. If it is a relative path it will be evaluated with respect +to the current directory (the typical usage), but it may also be an +absolute path. The binary_dir specifies the directory in which to +place the output files. If it is a relative path it will be evaluated +with respect to the current output directory, but it may also be an +absolute path. If binary_dir is not specified, the value of +source_dir, before expanding any relative path, will be used (the +typical usage). The CMakeLists.txt file in the specified source +directory will be processed immediately by CMake before processing in +the current input file continues beyond this command. + +If the EXCLUDE_FROM_ALL argument is provided then targets in the +subdirectory will not be included in the ALL target of the parent +directory by default, and will be excluded from IDE project files. +Users must explicitly build targets in the subdirectory. This is +meant for use when the subdirectory contains a separate part of the +project that is useful but not necessary, such as a set of examples. +Typically the subdirectory should contain its own project() command +invocation so that a full build system will be generated in the +subdirectory (such as a VS IDE solution file). Note that inter-target +dependencies supercede this exclusion. If a target built by the +parent project depends on a target in the subdirectory, the dependee +target will be included in the parent project build system to satisfy +the dependency. |
