You can list it in DISTFILES and it will be unpacked automatically,
e.g.

DISTFILES= ${DISTNAME}${EXTRACT_SUFX} \
libdivecomputer-subsurface-x.xx${EXTRACT_SUFX}

(or list the EXTRACT_SUFX in full if they differ between distfiles).

Then you often need a mv in post-extract, and maybe a little surgery on
the upstream Makefile.

Some ports get a bit more fancy to check the expected version (I do this
in Asterisk for the specially-compiled version of pjproject, for example).
