Building with qmake uses wrong library name

Building qt6 with cmake, then building another project (like the qt3d examples) produces build errors:

for some targets, it uses the wrong library name, like `-lQt::3DInput` rather than `-l3DInput`

 In particular, the generated lib/libQt63DExtras_debug.prl contains those wrong lib names. 3DExtras module depends on 3DInput and 3DLogic
