Actually, the gnutls library is not only providing tls, but also ssl.
So in the common case, gnutls is equivalent to openssl, modulo the
license.

(There are some minor differences with the API, mostly with exposed
internal functions and callbacks, but for most application, gnutls is
a equivalent replacement for openssl.)

Good point.  As the differences between http and https would be
handled by the curl library anyway, I guess we can pick any of the
libraries.

Because of this, I will recommend my personal preference with the gpl
license, gnutls.

Thank you for your information.  It made it a lot easier to take an
informed decision. :)
