Unless you statically built libcurl, libcurl is linked against libssh2 if you turned on SSH support, and whichever SSL library you built it against if you turned on SSL/TLS support. The two protocols were independently invented around the same time (1994-95) and are not compatible with one another. In particular, SSH is used mainly for file transfers and remote shell, while SSL/TLS is used to secure protocols that already existed at the time.

If you statically built libcurl, then you'll have to link your built product to libssh2 and the TLS/SSL library in addition to libcurl. That's how static libraries work.
