-- Add FreeBSD support and make optional dependencies controllable via the
-- port option framework. The upstream meson build hardcodes these as
-- Linux-only and always enables them; this patch maps them to the same
-- options that the previous GNU configure port provided.
-- Also force the use of the system vamp-hostsdk instead of the bundled
-- copy, and remove bundled include directories that are deleted by the
-- port's post-patch step.  Finally, install the main binary with the
-- lowercase name on FreeBSD.
