Issue

Failure

--enable-cloud-auth is broken when using libressl,
I personally don't use it, so I just disabled it, but could be useful if it gets fixed/ or if cmake/.configure checks for the feature.

./modules/cloud-auth/jwt-cpp/include/jwt-cpp/jwt.h:1158:33: error: invalid use of incomplete type 'struct ECDSA_SIG_st'
     auto rr = helper::bn2raw(sig->r);

Thanks for opening this issue.

jwt-cpp supports LibreSSL, but it requires reconfiguration:
https://github.com/Thalhammer/jwt-cpp/blob/master/docs/ssl.md

I guess we can make that configurable in our configure/CMake script and run the regeneration in case LibreSSL or wolfSSL is chosen.

That sounds as a good plan! Most probably, there are some libressl/wolfssl specific version tags which you can check on in the cmake/configure. Or if needed, make a configuration option, and push the problem up.
