There are a few things you must turn on in your VTK build.

<http://www.vtk.org/Wiki/VTK/Examples#Qt>If you just install a pre-build
version of VTK, I'm not sure if these things are already on?

To use Qt with CMake, you have to add:


FIND_PACKAGE(Qt4 REQUIRED)

INCLUDE(${QT_USE_FILE}

to your CMakeLists.txt file. I do not use Qt Creator, so I can't help you
with that. What I have done is use Qt Designer to make a .ui file and then
use it with a VTK program. There are some more tricky things to do in the
CMakeLists.txt for that - I will post them today.

Try a couple of these things and let us know if you're still stuck.

Thanks,

David
