Cmake build: Try to figure out at configure time which qt version to use

Selecting -DLYX_USE_QT=AUTO (which is the default now) will try
to figure out which QT-version to use.

The qt4 version will be used if it is installed and the installed qt5-version is <= 5.6
Otherwise use qt5 if it is installed.
