[vtkusers] CMake/Linking Issues VTK 6.1.0

[Christopher Mullins]

Interesting.  Are you able to build any of the VTK examples [1] against
your current install?  Also, have you tried with a clean build tree of your
application?  It sounds like something is getting cached when it shouldn't
be.

It might help if I could have a look at your CMakeCache.txt, or if you
could take a screenshot of your cmake-gui before the "configure" step.
