Could not find directory of OpenSSL installation, and this -sys crate cannot
proceed without this knowledge. If OpenSSL is installed and this crate had
trouble finding it, you can set the OPENSSL_DIR environment variable for the
compilation process.

Make sure you also have the development packages of openssl installed.
For example, libssl-dev on Ubuntu or openssl-devel on Fedora.

If you're in a situation where you think the directory should be found
automatically, please open a bug at https://github.com/sfackler/rust-openssl
and include information about your system as well as this message.
