[vtkusers] Cmake + VTK + QT issues

[Caleb Johnston]

Yes. I have done that with all three build platforms. That is what enabled
me to compile the QVTK class(es). But like I said in my post, it only
successfully compiled using QVTK on Linux and not on Mac OSX or Windows XP.
I have also tried compiling Paraview 3 on these two platforms because it
uses QT with VTK and Cmake but I get similar issues with both platforms...
