Since I selected
"GUI support" ON
"Build Qvtk" ON
"Build Examples" ON

I thought it would be only reasonable to have the Qvtk examples built as 
part of the main build. These were not enabled, so I've tweaked the 
Cmakelists files in Examples to do an if Qvtk is on, then do Subdir 
GUI/Qvtk, and in each of the actual example dirs, there was an 
INCLUDE(FindVtk.cmake), which isn't required if the examples are built 
as part of vtk itself, so I've surrounded these by an IF (NOT 
VTK_SOURCE_DIR) which should only be set when building vtk itself, so 
you can still build them as part of an external setup if you want. I've 
only modified Cmakelists files, so I'm not interfering with the Qt/Qvtk 
License :)

Linux : All examples working well on my setup. Lovely.
Windows. Didn't get anything with the imageviewer demo, but maybe it 
choked on my VTK_DATA_ROOT or something. Will have another look back at 
home tonight.

Many thanks for the classes, I'm sure they'll be very handy for a lot of 
people.

cheers
