CI is broken on Windows

[Jeremy Lainé]

All CI runs are failing on Windows due to OpenSSL headers not being found. Something has changed either in chocolatey or its openssl package, but I don't know what:

• does it no longer install development headers?
• has the default install path changed?

As I don't have access to a Windows box I'm in the dark here. Could someone using Windows please:

• run choco install openssl
• report back whether the OpenSSL headers + libraries get instaledl, and where

[Jeremy Lainé]

OK it looks as though chocolatey has changed the installation path, dropping the -Win64 suffix.
