See, e.g. the Debian package asterisk-opus:
https://packages.debian.org/source/sid/asterisk-opus

That package builds the opus modules as stand-alone modules out of the
tree of asterisk. It has a build-time dependency  on the binary package
asterisk-dev.

The list of files in it:

  /usr/lib/asterisk/modules/codec_opus_open_source.so
  /usr/lib/asterisk/modules/format_ogg_opus_open_source.so
  /usr/lib/asterisk/modules/format_vp8.so

IIRC res_format_attr_opus.so in Asterisk proper is by now good enough
and needs no patching.

Not by default.

You can either copy them to the Asterisk build directory (I do that in
another Asterisk package I maintain). The build system will just pick
them up and use them.

Alternatively, as suggested in the README above, build them outside of
the Asterisk tree (you'll need to point them to the asterisk source tree,
or at least to the installed asterisk header files and copy the
resulting .so files to the astmoddir (e.g. /usr/lib/asterisk/modules).

Which patch specifically? I'm not sure I follow.
