Freetype and libPNG detection in QT5
Bring back a patch that has been removed in 3597436e. The patch has been adapted to be compatible with QT 5.14.1
pkg-config is used in priority when trying to find the system QT5, which fails to find the superbuild version and use the system one instead.
Don't merge this right now. There might be other things to fix for the QT5 superbuild.
