CMake: Warn when using CMake 3.21.1

Changing a C++ source file can trigger rebuilds of a lot of other
source files that might include AUTOGEN'ed headers or sources.

See https://gitlab.kitware.com/cmake/cmake/-/issues/22531 for some
details. Fixed in CMake 3.21.2.
There are still files that are rebuilt even in 3.21.2, but it's less,
and it returns to the status quo of how it was in 3.21.0 or earlier
versions.
