That means youʼre using the cli tools, not the GnuTLS library. Perhaps
you need to have pkg-config installed as well in order for configure
to find the includes and the library.

Yep

'ns_get_foreign_selection' queries the clipboard to see what types are
available, and those are the ones it reports. Based on a quick google,
if we were to say "give me the data as JPEG anyway", thereʼs a chance
it might work, but of course the source might actually be TIFF, or PNG.

I canʼt find an official API to query the macOS clipboard for which
types it supports, but then again Appleʼs docs site and I rarely get
along.
