IRONically, hehe

The error says cmake is missing, not that it doesn't build on Windows.

Sounds like it's not your Rust project.

But cmake is required by Rustls (or more precisely, aws-lc-rs).

Even more precisely would be that it's a requirement for the default rustls backed on some platforms for some features. aws-lc-rs is a pain, but fortunately ring is just a feature flag away.

Sorry, it's not the point of what you were saying. You can tell I've been stung supporting users with this.
