The solution is to have missing services then?

Anyway, if you need cmake-time decisions, you should compile a simple C++ test 
that checks the Qt macro.

You can also process the output of:

gcc -std=c++11 -fPIE -E -dM -I$QTDIR/include -include QtCore/qglobal.h -xc++ 
/dev/null | grep Q_COMPILER

That will give you the full listing of detected features, matching exactly 
what will be available at compile-time.
