[vtkusers] Cmake + VTK + QT issues

Wed Jan 20 17:38:04 EST 2010

I have been able to successfully build VTK with QT.
I do have QVTKWidget.h (located in /usr/local/include/vtk-5.4).
I *don't* have moc_QVTKWidget.cxx but I do have QVTKWidget.cxx.
Also I have /usr/local/lib/vtk-5.4/libQVTK.a  --but thats it. I did not move
anything around, but does this configuration seem bad to you?
