I have no idea if cmake has an internal capability to compute checksums;
and that would be a question for their lists/forums/whatever.

You can of course run external tools, so something along these lines
would do it:

echo "checksums rmd160 `openssl dgst -rmd160 $(distfile_path) | cut -d '
' -f 2` \\" >> Portfile
echo "          sha256 `openssl dgst -sha256 $(distfile_path) | cut -d '
' -f 2`" >> Portfile
