This is the error that caused the startup app to build VTK8.2.0, but I see vtkCommonCorePython in vtkmodules.

This is the error that caused the startup app to build VTKmaster, but I see vtkCommonCorePython in vtkmodules.
I found that after I built the VTK, typing import vtk in python3 would report this error:

The last error is because Qt expects to be used with an rpath, but nothing adds the `LC_RPATH` entry to the library. I don’t know what the best solution here is, but I’d like to see a fix to it from CMake. The middle error looks like a Python version mismatch:
`…/BioMind.app/Contents/Resources/lib/python36.zip/…/Versions/3.7/Python`

The python version does not match, how do I need to solve it? I compiled vtk with python3.6, but after compiling, vtkmodules is in python2.7, I don’t know how to solve this python version mismatch problem.

Hmm. Looking at the `Python*` variables in `CMakeCache.txt` can probably show what is being found incorrectly. Make sure that `VTK_PYTHON_VERSION=3` too.

I am sure VTK\_PYTHON\_VERSION=3

What other `Python*` variables are set in `CMakeCache.txt`?
