If you had checked the manual, you would have read

--with-ssl=LIBRARY

Build with support for SSL (encrypted) connections. The only
LIBRARY supported is openssl, which is used for both OpenSSL
and LibreSSL.

So the argument is just pro-forma at the moment, although someday
maybe it will do something.

The options you need to use to point it at a non-default openssl
installation are --with-includes and --with-libraries [1].
