Tweak logic specifying libraries to link against VisualizationVTKCore
Tweak logic specifying libraries to link against VisualizationVTKCore

Since vtkRenderingFreeTypeOpenGL2 does not exist and vtkRenderingFreeTypeOpenGL, the
suffix OpenGL is hardcoded. Also move the logic in the FontConfig block.

Worth noting that vtkRenderingFreeTypeOpenGL has been removed in
version > 6.2.0 (See kitware/VTK@4f7460a5)
