[QGIS-Developer] Suggestion for improved macOS build compatibility testing

[Matthias Kuhn]

Hi Tom,

Sorry to hear that. In the past we had macOS continuous integration
tests in place but had to disable them, because the package manager used
there (homebrew) was breaking dependencies unpredictably (I don't think
that's unexpected news for you if you are building on mac though ;) )

There is no "verification machine" on linux, but there is a docker
image. However I am not sure how easy it is to modify this image put
headers in different folders and make all the executables (xxx-config)
return the modified paths - while keeping the infrastructure maintainable.

Alternatively, I would very much like to get the mac builds back up and
running. I don't think we can do this again with the upstream homebrew
repo since we don't want our pull requests flagged erroneous for
external problems. The best alternative I see is, that we need a curated
list of formulae in a separate repository, which would not only help the
testing but potentially also the release process. Would you be
interested in taking a lead on this?

Best regards

Matthias
