I've got OpenSSL 1.1.1w. The code is calling SSL_library_init which is a
define pointing to OPENSSL_init_ssl().
The code compiles just fine, but I don't understand why the code isn't
linking.
As for the original problem, updating to the latest version of the Neon
library doesn't help, I still get the same linking error. I''m sure there
is something fishy with my Debian install...
