Repair the MacOS bundle (.dmg package)

Ammar Nejatirequested to merge
fixMacBundle into main

The MacOS bundle was not functioning due to several problems, like

Library not loaded: @rpath/_libBornAgainGUI.so
  Referenced from: /Volumes/*/bornagain.app/Contents/MacOS/BornAgain
  Reason: image not found

The previous Python script, cmake/pack/fix_apple_bundle.py, is replaced by a zsh script which improves and corrects the bundle-producing mechanism:

  • Missing libraries are added.
  • All dependencies are found automatically up to an arbitrary depth.
  • The required Qt framework is added automatically (no need to mention Qt components manually).
  • References and RPATHs are calculated and set automatically.
  • Python dependencies are found and their references and RPATHs are set correctly.
  • Everything is documented in detail.

The produced MacOS bundle is tested successfully on Catalina (macOS 10.15, x86_64). Further tests are needed.
