Openvpn client or compiler tools

Is there a plan to have an openvpn client for Endless OS?
I tried running some binaries (for instance, with devilspie worked), but for openvpn I got this:

./openvpn: error while loading shared libraries: libssl.so.1: cannot open shared object file: No such file or directory

If there are no planes to have Openvpn, where can I find instructions for Endless OS developer tools installation, so I can compile with Endless OS compatible libraries?
