libssh2 version 1.8.0 needs a patch to compile with OpenSSL 1.1.1. See
https://github.com/Frugghi/iSSH2/issues/7
and the patch in
https://github.com/Jan-E/iSSH2/commit/6b2b61d56fc43642980aacc529c9d9d14263cebf#diff-47bf3a78aa165576c6c85a942ddf572bR6

You'd better upgradeto libssh2 1.9.0. It compiles fine in Xcode.
https://github.com/Frugghi/iSSH2 will create the necessary binaries for
Xcode.
