Subject: [PATCH] CMake: Raised required version to 3.5

CMake >= 4.0.0-rc1 removed compatibility with versions < 3.5 and errors
out with such versions passed to cmake_minimum_required(). 3.5.0 has
been released 9 years ago, so I'd assume it's available almost everywhere.

Furthermore at least 3.1 was already required, because that's the
version, which introduced CXX_STANDARD{,_REQUIRED}.

Also remove the FATAL_ERROR part, which has been ignored since 2.6. and
CMP0012 is now implicitly assumed to be NEW already.
