Enrico Forestieri b541692823 Fix configuring for Qt 5.8
They moved the QT_QPA_DEFAULT_PLATFORM_NAME definition to the newly
introduced qtgui-config.h header.
This fix is also necessary for cmake, but I don't know how to do it.
It would be simply a matter of using QtGui/qtgui-config.h instead
of QtCore/qconfig.h, if QtGui/qtgui-config.h exists.
