VTK includes X11/Xutil.h which introduces `AllValues` macro which collides with their declaration of `struct AllValues`. This leads to a compilation error in OpenCascade's IVtkDraw module. ``` error: expected identifier before numeric constant ... ``` This has already been solved inthe upstream: https://gitlab.kitware.com/vtk/vtk/-/merge_requests/7430

Actually, this problem is unrelated to the fix in VTK's upstream, I got it confused. It comes from #include <GL/glx.h> in src/IVtkDraw/IVtkDraw{,_Interactor}.cxx
Thanks for testing this. Opencascade hasn't been tested with vtk-9, it should have a restriction on <vtk-9 in RDEPEND, which is my fault, I forget to update this properly. I'm gonna look into this once my vtk-8 updates are finished.

This has been only partially fixed in the upstream: https://git.dev.opencascade.org/gitweb/?p=occt.git;a=commit;h=2c276f91da0 It was necessary to put `#undef`s in a few other places.
