In it's default set-up Emacs on macOS won't use libjpeg, libtiff,
libpng and giflib even if they're installed as those image types are
all built into NSImage, which is the default. So they're not
essential.

I'm not sure about libxpm, I think we have specific code in Emacs
itself to deal with them... Or maybe I'm thinking of some other X
bitmap format...?
