Is it possibly to detect which OpenSSL is used for a port?

[Naram Qashat]

So, I know that WITH_OPENSSL_BASE=yes or WITH_OPENSSL_PORT=yes can be set
by a user to say they specifically want either the base or the ports
version of OpenSSL. But is there a way to determine within a port which
OpenSSL is being used, either base or ports? Should I check if OPENSSLBASE
is set to /usr? Is there some other (or better) way to do it?
