[Paraview] Qt 4.2.3 Required for PV 3.1.0 Head

[Mike Jackson]

All a very good idea, and for the most part I agree totally with the  
logic. Would it be possible to put in an "over ride" as an advanced  
option into the CMakeLists file? Then I don't have to "hack" but  
still have the understanding that I am building a NON-supported  
version of ParaView? Or Allow Experimental Qt Support? Or Something?

Thanks
