[vtk-developers] NULL always returned from vtkPolyDataMapper::New()

[Kyle Lutz]

After adding "include(${VTK_USE_FILE})" right after
"include_directories(${VTK_INCLUDE_DIRS})" I now get the following
linker errors:

CMakeFiles/test.dir/main.cpp.o: In function `vtkRenderingCore_AutoInit':
/home/kyle/VTK/build/Rendering/Core/vtkRenderingCoreModule.h:44:
undefined reference to `vtkInteractionStyle_AutoInit_Construct()'

/home/kyle/VTK/build/Rendering/Core/vtkRenderingCoreModule.h:44:

collect2: ld returned 1 exit status

:-(. Any other ideas?
