Christian Tacke cf12379afa cmake: Use target_compile_features()
Problem at hand: dependents (like FairRoot) need to know the
minimum C++ standard level that FairMQ (and its headers)
requires.

The first idea is to let the targets export their
CXX_STANDARD value. First, this doesn't seem to work as
expected.

Second, target_compile_features() seems to be the better
way to go. It has a much better granularity, automatically
has the export feature, and thus should make dependents
behave correctly.

Also drop all of this enforeced CMAKE_CXX_STANDARD*
setting. If it's given, check it. But that's it.
