Yea, it's /usr/local on x86-64, based on what was required to make macos CI
work. I updated the wiki page, half-blindly - it'd be nice if you could
confirm that that works?

I needed something like the below to get (nearly?) all dependencies working:

brewpath="/usr/local"
PKG_CONFIG_PATH="${brewpath}/lib/pkgconfig:${PKG_CONFIG_PATH}"

for pkg in icu4c krb5 openldap openssl zstd ; do
pkgpath="${brewpath}/opt/${pkg}"
PKG_CONFIG_PATH="${pkgpath}/lib/pkgconfig:${PKG_CONFIG_PATH}"
PATH="${pkgpath}/bin:${pkgpath}/sbin:$PATH"
done

export PKG_CONFIG_PATH PATH

meson setup \
--buildtype=debug \
-Dextra_include_dirs=${brewpath}/include \
-Dextra_lib_dirs=${brewpath}/lib \
-Dcassert=true \
-Dssl=openssl -Duuid=e2fs -Ddtrace=auto \
-DPG_TEST_EXTRA="$PG_TEST_EXTRA" \
build

the per-package stuff is needed because some libraries aren't installed into
/usr/local (or /opt/homebrew), but only in a subdirectory within that.

Hm - what did you need this path for - I don't think that should be needed.

I think libintl.h / libintl.dylib are only in there. With meson that's the
only need for extra_include_dirs / extra_lib_dirs I found on arm apple.

Yea, that looks like a copy-and-pasto (not even from me :)). Think I fixed it.
