How to bundle external libraries (e.g. OpenCV) with a JUCE plugin for macOS

Hi, has someone an idea how to bundle external libraries (e.g. OpenCV) with a JUCE plugin for macOS?

I’m developing a JUCE VST3/AU plugin that uses OpenCV and other libraries. Currently users need to install these libraries via Homebrew to use the plugin. How can I bundle these dependencies within the plugin bundle so users can just drop in the .vst3/.component file and use it without installing anything?

I’ve tried adding the library paths and linking flags in Projucer, but I’m unsure about the correct way to include the actual dylibs in the bundle and fix the rpath issues.

Any help appreciated!

Ableton Live 11 fails to resolve rpath of dylib in VST3 plug-in, but other DAWs work

I have a VST3 plug-in that uses a precompiled dynamic C library (libphonon). On Windows, I put the .dll in C:\Windows\system32, and it works as expected in all hosts/DAWs that I’ve tried. Unfortunately, I don’t have access to the source of the dynamic library. On macOS, I place the dylib in /usr/local/lib, and it works fine on all hosts that I’ve tried except for Ableton Live 11. The machine I’m testing on has an M1 processor/Apple silicon. I’m compiling against JUCE 7.0.4. When I don’t link wi…
