SSL engines is a deep mystery to me. Are they working in other aspects or for
other OpenSSL applications on this machine?

What OpenSSL version is this?

And the _only_ difference was which licurl you linked with? That certainly is
very weird in my eyes. I can't explain that...

No they seem completely different.

The use of libssh2 doesn't affect HTTPS at all. Other than that libssh2 itself
may be built to use the OpenSSL crypto lib, and HTTPS in libcurl might also
use that same lib. But both libssh2 and libcurl can be built to use other
libs.
