[vtkusers] Cmake + VTK + QT issues

[Arnaud GELAS]

Has anyone successfully built vtk with recent Qt version (>=4.6.0, with 
delivered installers) on mac (carbon or cocoa)?

I have tried using Qt 4.6.0, 4.6.1 (mac, cocoa) and always had the same 
error because QtDBus.Framework is missing...
It is an open bug in Qt see http://bugreports.qt.nokia.com/browse/QTBUG-6429

Some time back I asked if QtDBus was really needed to build vtk with qt 
on the list: http://old.nabble.com/vtk-QtDBus--td26599452.html
But I did not get any answer... Is it really required to build vtk?

Thanks,
Arnaud
