You could have a look at GnuTLS available at
https://gitlab.com/gnutls/gnutls/ .

PKCS7 is supported, cf.
https://www.gnutls.org/manual/html_node/PKCS-7-API.html

There seem to be four main contributors to GnuTLS adding two patches
a day:

There is LibreSSL as well which is a fork of openssl. Guess that too should be fine.

LibreSSL has the same license issue (i.e. it's GPLv3-compatible but GPLv2-incompatible) as OpenSSL.
