I have been able to reproduce it.  It seems to be related to this change:

  http://review.source.kitware.com/#/c/18944/1

I have ITKVtkGlue ON, ITK_WRAP_PYTHON ON (although I do not know if
they are both required).

It happens with both CMake master and CMake 3.1.0 (although I get two
WARNINGS with CMake master and a single warning with CMake 3.1.0).

Without the above change, errors occur on Windows, when
${ITKVtkGlue_VTK_DEFINITIONS} has content.  On Unix, when it does not
have content, it appears to cause issues with the above change.

What is the best approach here?

Thanks,
Matt
