I made an installer for mac of a ParaView-based application. What I did:

1. Execute `/Applications/Qt/5.9.9/clang_64/bin/macdeployqt paraview_clone1.app`
2. Copy `/Users/user/Desktop/Project/paraview_clone1.app` into `/Users/user/Desktop/ProjectInstaller/packages/com.vendor.product/data`
3. cd into `ProjectInstaller`
4. Execute `/Applications/QtInstaller/bin/binarycreator -c config/config.xml -p packages Project-installer`

`macdeployqt` is supposed to add all the dependencies but I got this error:

`No module named paraview.detail.pythonalgorithm` and `No module named paraview.simple`

What I am missing?

If I explore what `macdeployqt` added to my application I see all this:

You probably missed the Python libraries. They should be placed under `foo.app/Contents/Python`. They’re probably in a `lib/python3.x/site-packages` directory near the original app location.
