On macos, the build is failing with 0.21.1, a patch has been landed to fix the issue, see https://github.com/rockdaboot/libpsl/pull/166 Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/4876>
So build failures on master don't break our build and CI. https://github.com/rockdaboot/libpsl/pull/164 Part-of: <https://gitlab.freedesktop.org/gstreamer/gst-build/-/merge_requests/213>
libpsl is a dependency if libsoup that has an upstream Meson build system (in master only). libsoup also needs libxml2 but we already have a wrap file for it. The only remaining dependency that must come from the system is sqlite3.
