[vtk-developers] VTK Python & BUILD_SHARED_LIBS=OFF

[David Gobbi]

Hi Utkarsh,

The following MR will address some of the issues:
https://gitlab.kitware.com/vtk/vtk/merge_requests/3075

Relevant changes the MR are:
1) The VTK Python extension modules are exported as targets.
2) When an extension module is imported, it imports the extension modules
that it depends on.
