Does this port not support non x64 Windows ("supports": "!(windows & (arm64 | uwp | x86)")?

Also missing a version database update with vcpkg x-add-version dispenso.

Good callouts, thanks! I hadn't been able to test on 32-bit windows previously. I've created a fix and I'm testing it. I'll also make the version database update change and get back to you later this week with PR updates.
