This adds aalib, gi-docgen, libheif, libmng and vala.
The homebrew list was originally minified since all-deps-uni was
ported from the treatment of vcpkg on build/windows all-deps-uni.
But since on homebrew we don't build anything, let's install them.
This also adds to the list deps already installed recursively.
Hmmm why this was not already enabled? On my tests, it works.
Don't remember why I have not handled this before.
This commit also reorder the xdg-mail position on macOS script.
This was tested with both in-house MacPorts, in-house HomeBrew and
legacy CircleCI builds and I confirmed it works (it is needed only
by the in-house MacPorts builds).
The Hessele runner started to complain about the artifacts size and
the macports/ dir as artifact is not needed on a non-splitted job.
It was a leftover from the inspiration from Flatpak scripts.
(On Flatpak it is needed becase if we don't pass .flatpak-builder as
artifacts the gimp job will not know that babl and gegl were built)
When MacPorts or Homebrew prefix is the standard one, not a custom installation,
let's use the host macOS/SDK since this is the expected by both toolkits which
provide binaries only for host. Otherwise, we get warnings from the linker.
(We will keep assuming LSMinimumSystemVersion is desired on custom installs,
like our officialy distributed binaries which are built from a custom install)
More preparition to x64 support
As a ugly regression, it will not be possible to create .dmgs on
forks anymore without an explicit "Run pipeline" from a Developer.
I hope to fix that when we take our sponsored runner from CircleCI.
Thanks to various improvements on babl and GEGL repos they now build cleanly.
So, let's take advantage of Clang senstive semantic analysis on future builds.
For now, this is limited to such projects and on GNU Clang and Apple Clang,
since there is still a bit of work to do on Clang-CL (MSVC) side.
This makes the macOS builds way faster (aprox. 1hr instead of 3.5hr)
thanks to local caching of GNOME runner. We, however, still need to
split them since the timeout is relatively small on such runner.
By using a pre-made .DS_Store file, this bypasses Apple Script
restrictions which made impossible to set custom background on CI.
We don't have rights to tweak com.apple.TCC like gimp-macos-build.
.DS_Store is a binary file, but it is tiny and rarely updated,
which follows the precedent of build/windows/store/*.pfx.
