[Csnd-dev] Signing MacOS bundle

Hi!

I managed to get a signed tryout MacOS  bundle of CsoundQt7+Csound7 done
(this is really a tryout but can be usable):
https://tarmo.uuu.ee/owncloud/index.php/s/BgNpnqnSRjqXSy1

It is based on Csound7-beta.8, downloaded from Github actions artifacts.
What I noticed:
- $APP/Contents/Frameworks/CsoundLib64.framework/Versions/7.0/CsoundLib64
gave at first an error:
'code has no resources but signature indicates they must be present '.
I needed to remove the signature and resign again. I don't know if it
requires attention from Csound side.

- the *libs* folder in CsoundLib64.framework folder causes signing error
'Unsealed contents present in the root directory of an embedded framework'
- see
https://developer.apple.com/library/archive/documentation/MacOSX/Conceptual/BPFrameworks/Concepts/FrameworkAnatomy.html
I needed to move the *libs *folder away from framework root and placed it
to resources next to opcodes' dir.
I did not do the install_name_tool changes as the libraries were only for
portmidi. It would be nice to have the framework immediately with suitable
structure so it easy to develop MacOS apps based on it.

What do you think?
