[Paraview] Forcing a Qt version

Tue Oct 7 18:38:50 EDT 2008

I gave up and employed the dirtiest solution. Deleted Qt 4.3.4 and used 
Qt 4.4.2. Nothing more to choose, CMake finally got convinced that I 
only have one Qt version...

...In the end, instead of forcing a Qt version CMake forced me to delete 
one of them :o(
