CMake Useful Variables. CMake uses and defines many variables, which can be used in CMakeLists.txt files. NOTE: As of CMake 2.6.0 many of these variables have been officially documented in TXT and HTML files released with CMake. You may still see some useful variables here that haven't yet been documented in the official documentation, although the number of these diminishes with every release.
