[vtkusers] CMAKE + VTK + QT

Tue Sep 15 18:29:38 EDT 2009

I just looked at the Ubuntu VTK packages that your cmake configure step is 
picking up.  They are broken wrt building the VTK/Qt examples.
So just be sure to specify your VTK instead of letting it pick up the 
installed one.  And delete your CMakeCache.txt file if you need to start again.
