I was kinda assuming you'd know which library it should link into. But..

$ strings /usr/lib/x86_64-linux-gnu/libssl.so.1.0.0 | grep OpenSSL
OpenSSLDie
SSLv3 part of OpenSSL 1.0.1t  3 May 2016
TLSv1 part of OpenSSL 1.0.1t  3 May 2016
DTLSv1 part of OpenSSL 1.0.1t  3 May 2016
OpenSSL 1.0.1t  3 May 2016

works at least for me. maybe this helps you?
