    Cmake build: Correct configuration if set LYX_BUNDLE=ON
    
    Patch by Patrick (pdvisschere at edpnet.be)
    Citing:
    With some changes I could get it to work (patch included). One will also
    have to define the locations of the Qt5-plugins and Qt5-libs folders
    (`QT5_PLUGINS_DIR` and `QT5_LIBRARY_DIRS`).
    
    Maybe not all plugins/imageformats are used/needed by lyx, but they are
    all copied now, except for `_debug` versions which are excluded.
    Starting with Qt-5.12 it seems not possible anymore (or at least not
    easy) to link to the `_debug` versions of the qt5-frameworks (with
    cmake). And installing them into the bundle also does not work. So right
    now this is not a big loss.
