[vtkusers] Can't run build vtk from source with python wrappings

Fri Oct 26 13:41:38 EDT 2018

Hi,

I see. As an alternative approach, you could also look into building VTK
python package using https://github.com/jcfr/VTKPythonPackage

This is what is used to build the VTK python wheels. That said, note that
we are are not yet officially supporting VTK python wheels.
