CMake Tools is not the same as CMake. There are many great resources around to learn how to use CMake.
- Jason Turner's C++ Weekly - Intro to CMake is a good introduction.
- CMake's documentation
- CMake's "Mastering CMake" book
- "Professional CMake"- a $30 book by Craig Scott (one of the maintainers of CMake).
