CMake is a the cross-platform, open-source build system. CMake is a family
of tools designed to build, test and package software. CMake is used to
control the software compilation process using simple platform and compiler
independent configuration files. CMake generates native makefiles and
workspaces that can be used in the compiler environment of your choice.
