[CMake] Building a Debug Project against a Release VTK

I _understand_ the error. What I need to know is if there is a way to actually build my code with Debug ON but leave VTK in release mode? I do this on other platforms (OS X) so this just seems like I am missing something simple.

This is actually a question for the VTK users list.  The UseVTK.cmake
file provided by VTK is *very* strict about matching compiler settings.
 That is what is creating the warnings, not CMake itself.  You can
probably avoid the problem by not using UseVTK.cmake directly.  Instead do

FIND_PACKAGE(VTK)

and then use the resulting variables for link directories and include
directories yourself in calls to LINK_DIRECTORIES and INCLUDE_DIRECTORIES.
