In order to provide build and provide the jack plugin with the prebuilt binaries of gstreamer we distribute with releases, we can not depend on an external dependency nor can we ship plugins linking to libraries we don't provide. We can also not provide jack ourselves, as it would likely cause a mismatch with the jack daemon on the host. Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/4350>
