Cargo expand fails on windows within deeply nested folders about cbindgen

[emilio]

I don't think this is actionable on cbindgen's side unless we can somehow shorten the window paths or something... If you think there's anything we could do better here let me know and we can re-open / fix it :)

This workaround seems to work for me.

from: #347

    let crate_dir = env::var("CARGO_MANIFEST_DIR").expect("invalid manifest dir");
    env::set_var("CARGO_EXPAND_TARGET_DIR", crate_dir.clone());

Could be a cargo expand issue perhaps, or the way cbindgen is invoking cargo-expand 🤷‍♂️

Yeah this seems unlikely to be a cbindgen bug per se, and more of a windows limitation with long command line arguments / paths...

ya. I run into permutations of this in various different ways in rust/javascript ecosystems. Should windows "be better"... Of course. Will it? ...no
