libjack.0.dylib failed at library validation on OSX Monterey

[luluz66]

Describe the bug

Musescore 3.6 doesn't work with jack2. When musescore is launched from command line, it prints out the following error:

dlopen error : dlopen(libjack.0.dylib, 1): image not found
dlopen error : dlopen(/usr/local/lib/libjack.0.dylib, 1): no suitable image found. Did find:
/usr/local/lib/libjack.0.dylib: code signature in (/usr/local/lib/libjack.0.dylib) not valid for use in process using Library Validation: mapped file has no cdhash, completely unsigned? Code has to be at least ad-hoc signed.
/usr/local/lib/libjack.0.dylib: stat() failed with errno=22

This is also reported on Musescore. https://musescore.org/en/node/326520. (I'm not sure whether it's a musecore issue or a jack2 issue)

Environment

• JACK Version: jackdmp version 1.9.20
• Operating System: macOS Monterey 12.0.1
• Installation: JACK 1.9.20 macOS-universal from https://jackaudio.org/downloads/

Steps To Reproduce

# Assuming Musescore 3.6 is installed
mscore

Expected vs. actual behavior

Expected behavior: Musecore 3.6 able to find libjack library. Actual behavior: Musescore 3.6 reports that libjack.dylib failed for library validation.

dlopen error : dlopen(libjack.0.dylib, 1): image not found
dlopen error : dlopen(/usr/local/lib/libjack.0.dylib, 1): no suitable image found. Did find:
/usr/local/lib/libjack.0.dylib: code signature in (/usr/local/lib/libjack.0.dylib) not valid for use in process using Library Validation: mapped file has no cdhash, completely unsigned? Code has to be at least ad-hoc signed.
/usr/local/lib/libjack.0.dylib: stat() failed with errno=22

that is unexpected, the jack macos builds have an installer so those libraries should not be in quarentine. I guess tools need to do trickery to allow to load such libs on macOS :shrug:
