I would assume that most people casually building Emacs would have no
idea what either Cairo or HarfBuzz is.  Perhaps it would be helpful to
say something like "uses the Cairo graphics library, but without the
HarfBuzz font rendering library"?

'Casually building Emacs'? Is that possible? :-)

If they're doing it casually, would explaining Cairo and HarfBuzz
help?

I would consider myself a casual builder of Emacs. :-) On one 
machine, I compile and install Emacs from source. Not to stay up 
to date with development but just to have the latest Emacs 
release. (When I first installed that machine, there were no 
pre-built packages of a recent Emacs available.)

And yes, I think if I'd run into this problem, I'd appreciate the 
extra information. I mean, of course I would google "Cairo" and 
"HarfBuzz", but knowing what I'm looking for would make fixing the 
problem easier.

Just my €0.02.

My fees are considerably higher than that, but this one Iʼll do for
free. Done in master.

Sure.  Building Emacs is super-easy, and lots of people not involved
with development does it.

Yes.  :-)
