  openssl: dynamically load libssl and symbols (optionally) Provide an interface around OpenSSL to dynamically load the libraries and symbols, so that users can distribute a libgit2 library that is not linked directly against OpenSSL. This enables users to target multiple distributions with a single binary. This mechanism is optional and disabled by default. Configure cmake with -DUSE_HTTPS=OpenSSL-Dynamic to use it.
