[CMake] CMake can't find the correct Qt installation paths

[Andreas Pakulat]

Hi,

as Michael said, don't move Qt around.

In fact Qt itself does not support this at all, so a Qt installation
that is moved after the install process and without re-running the
patching or a writing a qt.conf file is to be considered a broken Qt
installation. It'll also not find plugins etc. itself either.
