[Paraview] Forcing a Qt version

[Clinton Stimpson]

If there's a qmake in your PATH, it takes precedence over whatever you 
set QTDIR to be.
By the way, the use of QTDIR has been deprecated by Trolltech.
Another thing you can do is set QT_QMAKE_EXECUTABLE in the cmake-gui 
before you hit configure for the first time, and it won't matter what 
your PATH is.
