[Cmake] hardcoded prefix for QT_WRAP_UI inputs

Probably not.

The QT wrapping commands in cmake were not written by the main CMake
authors, and since they don't use them, you'll have to put up the QT mods
authors' less than ideal response....

Franck (author of QT_WARP_UI) and I (author of QT_WRAP_CPP) do not currently
have the time to maintain/enhance these commands beyond their basic
operation - with which there hasn't been any problem recently. We suggest
looking at the CMake Source. The QT_WRAP_* commands are really quite simple.

Sorry we can't be more help.

Ian.
