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

[Evgeniya Malikova]

No, looks like updating DYLS_LIBRARY_PATH didn’t solve the problem.

However, vtkpython works well. Just come across this description:
https://stackoverflow.com/questions/48148376/running-vtk-from-python-not-just-vtkpython

The similar check gives me similar list of dependencies with vtk python depending on libpython3.6m.dylib:
otool -L libvtkCommonCorePython36D-8.2.1.dylib
libvtkCommonCorePython36D-8.2.1.dylib:
	@rpath/libvtkCommonCorePython36D-8.2.1.dylib (compatibility version 1.0.0, current version 1.0.0)
	@rpath/libvtkWrappingPython36Core-8.2.1.dylib (compatibility version 1.0.0, current version 1.0.0)
	@rpath/libvtkCommonCore-8.2.1.dylib (compatibility version 1.0.0, current version 1.0.0)
	@rpath/libvtksys-8.2.1.dylib (compatibility version 1.0.0, current version 1.0.0)
	/usr/lib/libc++.1.dylib (compatibility version 1.0.0, current version 400.9.0)
	/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1252.0.0)

otool -L vtkpython
vtkpython:
	@rpath/libvtkWrappingPython36Core-8.2.1.dylib (compatibility version 1.0.0, current version 1.0.0)
	@rpath/libvtkPythonInterpreter-8.2.1.dylib (compatibility version 1.0.0, current version 1.0.0)
	/usr/lib/libutil.dylib (compatibility version 1.0.0, current version 1.0.0)
	@rpath/libpython3.6m.dylib (compatibility version 3.6.0, current version 3.6.0)
	@rpath/libvtksys-8.2.1.dylib (compatibility version 1.0.0, current version 1.0.0)
	@rpath/libvtkCommonCore-8.2.1.dylib (compatibility version 1.0.0, current version 1.0.0)
	/usr/lib/libc++.1.dylib (compatibility version 1.0.0, current version 400.9.0)
	/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1252.0.0)
