// This test checks the functionality of `tracked_path::path`, a procedural macro
// feature that adds a dependency to another file inside the procmacro. In this case,
// the text file is added through this method, and the test checks that the compilation
// output successfully added the file as a dependency.
// See https://github.com/rust-lang/rust/pull/84029
