[vtk-developers] vtk-8.2.0-rc2 problem building wheels

[David E DeMarle]

So https://gitlab.kitware.com/vtk/vtk/merge_requests/5021 which makes
vtkPython optional is necessary but there is more work to be done.
We also need https://github.com/demarle/VTKPythonPackage/tree/bump-to-8.2
or something like it to put the .py's and .so's into the places that
auditwheel expects to find them.
Then we can make a wheel.

However we still need run time changes so that python and library paths
cope with the new intermediary vtkmodules directory (see
https://gitlab.kitware.com/vtk/vtk/commits/741fffb). Specifically the code
in vtk/vtk.py isn't loaded automatically like vtk/__init__.py would be and
it when I force it there are still path issues that I can thus far only
work around with hacks like extending LD_LIBRARY_PATH.

It looks doable from 8.2.0 but I'm out of time on this. So I suggest we
release 8.2.0 as it is and fix it, if required in 8.2.1. OK?
