You need to de-compose the S/MIME message to get the CMS objects.
Despit ethe name, gpgsm does not known about S/MIME (or MIME at all) and
thus can't parse it. That is actually the same as with PGP/MIME which
can't be handled directly by gpg [1].
In gnupg/tools/ you can find a basic MIME parser but it is not well
documented and only used for manual testing.
Salam-Shalom,
Werner
[1] Actually encrypted PGP/MIME messages can be directly decrypted gpg
due to a pecularity of the PGP/MIME format.
