Good morning 
Let‘s say I have a shell program whos installation path can be configured.
What would I have to set it to for deploying a macOS app so the shell program is included and can be called?
thanks in advance

To be self-contained the way good Mac apps are, the helper needs to be included in Bundle Contents/Helpers and should be able to run from within the app bundle when the app is placed at any location.
If you need to install privileged tools into the system then you’ll need to make a .pkg installer.
