contrib: allow building with CMake 4.x

Support for versions older than 3.5 has been dropped.
The minimum version can be forced in most cases via a configuration flag.
We require 3.28 for proper tvOS support anyway.

This will be needed until these contribs are updated. Although some are not
maintained anymore.
