To remove some of the mystery from it, this just means that you would
like to auto-initialize 4 modules for the vtkRenderingCore module -
namely vtkInteractionStyle, vtkRenderingFreeType,
vtkRenderingFreeTypeOpenGL and vtkRenderingOpenGL.

You could add message("VTK defines: ${VTK_DEFINITIONS}") to a CMake
file if you would like to extract the proposed compiler definitions
and export them to another build system. Hopefully that will make
things easier for others wanting to go this route.
