I've now tested the macOS binaries on my computer, with help of ~/.julia/artifacts/Overrides.toml, and everything seems to work fine now!

The only thing I am unsure about is whether to change the version (as this PR does not right now) or else leave it... @barche @giordano advice?

We're going to decouple the JLL version from the upstream one, so versioning it's mostly up to you. In particular we want to not use build versions going forward, so the safest option is to bump the patch version.

Other the version number (which looks ok to me), I take this can be merged?

From my POV it is ready for merging

OK, since the versions are decoupled now anyway I guess it's most logical to just go ahead and base the JLLs for julia 1.4 and 1.5 also on libcxxwrap-julia 0.8.2?

@barche they all will be based on the same git commit of libcxxwrap-julia, if you mean that? But that was always the plan, wasn't it?

Well, I was going to bump the upstream versions in sync, but actually it's better not to. This way, if bugs are fixed we can just update all JLLs. So basically nothing is holding back the creation of the other JLLs now, I think.

@barche exactly -- see also PR #2106 :-)
