Hi,

Some of these instructions are not advisable:

1. Never edit any file in the codebase. For cmake use -DOPTION=VALUE (eg. -DUSE_BUNDLE_DEFAULTS=ON)
2. Never make install SDR++ on MacOS. Especially when enabling bundle defaults. It is meant to be built into a bundle, NEVER installed. It is garanteed to break or cause issues when trying to uninstall.

After the bundle is built, it can be installed and run like any other MacOS bundle.

Please either edit this post to fix it or remove it before people try to follow it.
See the CI script for how to build the bundle, it's a single script to execute.
