Warn if using CMake 3.20.0 due to potential cyclic dependencies

Browse Source 
CMake 3.20.0 can create autogen-related cyclic dependencies that are
only detected at build time by Ninja, which then fails with a build error.
Warn and advise to use a different CMake version instead.

Pick-to: 6.1 6.0
