I'm not very familiar with HVF or meson - I am not sure I understand
what you're suggesting here (and a few attempts to grep around for an
example didn't turn up anything that looked helpful). Are you suggesting
some sort of build-time auto-detection, a "dumb" configuration switch
that a user could use to manually enable this, or something else? And/or
is there an example you could point me to of what you're thinking?
