[Bug]: missing JACK support on macOS

[umlaeute]

Detailed steps on how to reproduce the bug

• install JACK for macOS
• build a standalone with -DJUCE_JACK
• run the application, and open the audio-settings
• notice that it does not offer JACK as an audio device

What is the expected behaviour?

i would expect optional JACK support, just like under linux.

it seems that it would be sufficient to also search for libjack.0.dylib (resp libjack.dylib) when trying to dlopen() the jack libraries:

I tried looking into this a little bit over here: https://github.com/plugdata-team/JUCE/compare/opengl_test...Wasted-Audio:JUCE_plugdata:feature/jack4all

Specifically for the plugdata project. However I haven't been able to successfully build test for macOS yet.

It works btw:

The downside is that you still have to deal with the limitations of the JACK implementation in JUCE: https://github.com/juce-framework/JUCE/issues/333
