However, the auto-init function that registers the vtkObjectFactory overrides (so that matplotlib's subclass of the vtkMathTextUtilities class is created by default) at startup is not being called, unlike the corresponding auto-init for vtkRenderingOpenGL.

It would be useful to see the verbose compiler invocation with the
defines CMake is passing through - that is where we would should see
the autoinit stuff working. I know David Lonie is working on this,
perhaps he has already hit this issue? I can help debug the autoinit
stuff if that doesn't seem to be working.

Thanks,

Marcus
