Unable to import the SlicerVmtk libraries` in Slicer4.7, macOS

Support
1

I am using vmtk as an extension in 3D Slicer4.7. It works fine on Windows,
but fails to import dynamic libraries in macOS by reporting Unable to import the SlicerVmtk libraries.

qt-scripted-modules can be accessed, but qt-loadable-modules can not be
found. It seems that rpath is incorrect. Anybody knows how to solve it?

Errors in Python interactor:
