[native_toolchain_rust] Compilation error when adding a dependency

[Rahiche]

I'm using native_toolchain_rust to create a package, the sample example in the repo builds with no issues.

I add any dependency (for example: image = "0.25.2") and it can no longer compile, and I'm trying to find where I can get the logs to debug the issue, any advice on how should I debug this.

Xcode build done.                                           15.4s

To reproduce just update cargo.toml, flutter clean and then build again:

[package]
name = "flutter_ffi_plugin"
version = "0.1.0"
edition = "2021"

[lib]
crate-type = ["cdylib"]

# See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html

[dependencies]
image = "0.25.2"

Yeah, this fails when compiling the build.rs from dependency crates for host. I think it is caused by XCode putting things from /Content/Developer into PATH. I remember dealing with this in cargokit, I'll need to do same thing here.

Still would be nice to figure out why the relevant error is only present in verbose log at a completely different spot.

Should be fixed in 0.1.0-dev.5.
