It looks like openssl is too old on your platform. It's failing to generate a dummy keypair.

Specifically, the -addext option seems unsupported. You can try editing https://github.com/NTAP/quant/blob/master/test/CMakeLists.txt#L54-L65

Thanks. I upgraded openssl to 1.1.1 from 1.1.0 and make runs successfully now.
