[Paraview] Forcing a Qt version

[Renato N. Elias]

Hi Michael,

there's something overriding my QTDIR because CMake still points to the 
wrong Qt version. I've set both QT_QMAKE_EXECUTABLE and QTDIR to 3.3.4 
version, but CMake still returns me a warning that I'm using an 
unsupported version of Qt. Now I'm trying to understand all that CMake 
sintaxe in FindQt4.cmake and UseQt4.cmake modules.

weird, isn't it?!
