One of the benefits is that this adds support for building with OpenSSL 3.0 versions without breaking support for building with 1.1.1.
As part of the work, the assumption that there is an /archive/ in the download path is removed.
Furthermore, cmake modules for finding OpenSSL are updated in order to support 3.0.
