[Insight-developers] [Insight-users] CMake config problem: ITK + GDCM 2 + VTK

[Stephen Aylward]

Yeah - that's probably it.

I could add a AND NOT GDCM_USE_VTK to the VTK_VERSION test in the
MetaIO CMakeLists.txt file..ugly ugly ugly.

I'd rather GDCM didn't export VTK's variables, but I guess it is
necessary if the libraries it exports now depend on VTK.  However, if
GDCM_USE_VTK only creates apps within GDCM 2 that depend on VTK, and
its libraries never depend on VTK, then GDCM should be fixed.

Other ideas?
