Hey I am trying to use this crate for building a cad model. I am running it on windows. I am getting the following error:

error: failed to run custom build command for `occt-sys v0.2.0`

  is `cmake` not installed?

  build script failed, must exit now
  note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

What should I do ?

Hi,

This library is not yet well supported on windows. However, it simply looks like you don't have cmake installed. That might not be the only issue you'll run into though, so you could also try installing opencascade 7.7 and building your project by passing default-features = false in your Cargo.toml for this crate. Or if you're working in this repo directly, pass --no-default-features to cargo when building.
