If you had checked the manual, you would have read

    --with-ssl=3DLIBRARY =


         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].
