[ITK-dev] ITK bugs with recent patch

Tue Apr 21 13:23:55 EDT 2015

Hi Bill, Hans, Matt,

To account for the different VTK backends, you could introduce an option
named ITK_VTK_BACKEND that would default to "OpenGL", that way you would
specific VTK components using "vtkRendering${ITK_VTK_BACKEND}".

To account for the fact recent version of VTK do not provide
vtkRenderingFreeType${ITK_VTK_BACKEND} [1], you could add a compile test
internally calling "find_package(VTK)" and checking if the target
"vtkRenderingFreeType${ITK_VTK_BACKEND}" exists using "if(TARGET
vtkRenderingFreeType${ITK_VTK_BACKEND})".
