Hello there,
CMake is not a build system itself; it generates another system's build files. So it might come in managed Code.
CMake is cross-platform free and open-source software for build automation, testing, packaging and installation of software by using a compiler-independent method.
I hope this information helps. If you have any questions please let me know and I will be glad to help you out.
