VTKTargets-none.cmake references libraries that are actually Python modules.
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
When compiling VTK with Python support then various entries are generated in the VTKTargets-none.cmake file that import packages that are apparently Python extension modules.
While this may not be a problem for installations from source it creates some difficulties for packaging, i.e. these libraries must be part of the development packages even though they should not be linked against and should go into the according python packages.
