[Paraview] Forcing a Qt version

[clinton at elemtech.com]

I do multiple Qt versions simply by modifying my PATH before the first time I 
run cmake on an empty build directory.

To verify that, I can run "qmake --version" from a console/terminal, to make 
sure its the right one before I run cmake for the first time.
