On osx with conda (python 3.6/3.7/3.8), paraview Python modules are imported successfully while pvpython fails to run with the following error:

+ pvpython --version
dyld: Symbol not found: _PyObject_GenericGetAttr

I know Python modules on osx are tricky to get right, so I tried to set the related option:

-DVTK_PYTHON_OPTIONAL_LINK=OFF

And this time pvpython works fine while "import paraview" fails with

Fatal Python error: _PyInterpreterState_Get(): no current thread state

which is the famous error you get when you link to Python libs on osx instead of using -undefined dynamic_lookup.

cc @ben.boeckel as I know you are familiar with this kind of issues
