Undefined reference to SSL_get_peer_certificate at compile?

[LinuxRocks2000]

When compiling from source, cargo makes it to the linker step and fails with

error: linking with `cc` failed: exit status: 1

Looks like a problem with bad native dependencies.

What system are you building for? Have you tried cargo update?

Note that you can build Websocat without TLS support if needed.
