I know this is a "known issue" so to speak as it's made clear in the readme that only OpenSSL 1.0 is supported currently but this version is not available in distributions of linux such as Debian Stretch.
A workaround for Debian Stretch is to install libssl1.0 and libssl1.0-dev.
The libssl1.0-dev package has the nasty side-effect of removing libssl1.1-dev as they cannot exist side by side unlike the libssl1.0 and libssl1.1 library themselves.
