I am trying to build POCO 1.9.4 using cmake and the version of OpenSSL in POCO/openssl (submodule) on Linux (Fedora 29) using gcc version 8.3.1 20190223 (Red Hat 8.3.1-2) (GCC) . These are some of the warnings I'm getting:

I get similar warnings when building POCO with the OpenSSL installed using dnf (OpenSSL 1.1.1a 20 Nov 2018).

Is this a normal behavior or am I doing something wrong? Which version of OpenSSL is required by POCO?

Thank you so much in advance.
