CMake is a cross-platform system for automating project builds. This system is much older than the PVS-Studio static code analyzer, but no one has tried to apply the analyzer on its code and review the errors. CMake is a cross-platform system for automating software building from source code. Introduction.

With a clearly defined API, you can establish a set of rules that outsiders need to follow if they wish to use your code.
