[bug] Error while cross-compiling mac m1 -> windows-msvc

[pashokitsme]

Describe the bug

I'm using xwin to cross-compile
When i run cargo tauri build --target x86_64-pc-windows-msvc --runner cargo-xwin it fails due to wrong clang arguments

Reproduction

1. Minimal tauri project
2. cargo tauri build --target x86_64-pc-windows-msvc --runner cargo-xwin

Expected behavior

No response

Additional context

Funny, but it compiles if i create ln -s llvm-lib lib.exe and run cargo tauri build --target x86_64-pc-windows-msvc. With updater plugin it works when i run two commands in a row: without cargo-xwin and with. But anyway it's not correct behavior

[FabianLars]

I may be missing something but this sounds like a cargo-xwin issue to me, not tauri 🤔 Especially since our plain xwin guide still seems to work as far as i can tell https://tauri.app/v1/guides/building/cross-platform#experimental-build-windows-apps-on-linux-and-macos

(p.s. i can reproduce your issue on my machine too but no idea how to fix it)

[pashokitsme]

Seems it happens somewhere around tauri_winres. Also, it reproducible by this:

// build.rs
fn main() {
    tauri_winres::WindowsResource::new().compile().unwrap()
}

Can embed-resource (dependency of tauri_winres) cause this error or this line isn't related to it?
And also, cargo-xwin does something with cmake files to fix issues like this one (but someone calls clang-cl, not cmake file)

[pashokitsme]

Will be fixed by rust-lang/cc-rs#911
