Original Issue
The problem: I need to locate the target dir from the build script.
The solution: I'd love a CARGO_TARGET_DIR environment variable. There's clearly precedent for this as cargo doc depends on such a thing today.
@jyn514 suggested I reach out to the Cargo team for advice.
Currently the Windows crate has been using various hacky solutions that are problematic.
