I also add no-comp -DOPENSSL_NO_HEARTBEAT no-md2.
no-md2 might be a default.
Check Configure Options at https://wiki.openssl.org/index.php/Compilation_and_Installation for some other things you might not need, like no-srp no-psk no-dtls no-npn no-krb5 etc. If this is a dedicated library for your application, I suggest you disable all features and ciphers you won't be using, for example, no-bf no-sha1 no-md5 no-seed etc....
If you control both ends, you could even distill it down to a single protocol cipher suite, like ECDHE-ECDSA-AES128-GCM-SHA256 with TLS1.2.
