Allow to "include" files not below the folder where Cargo.toml resides.

My project builds a number of cross-platfrom wasm files I would like to distribute with my package (each target will have a native, target specific runtime to run them).

They get built into out_dir or target by rustc.

I would like to include them via a glob rooted outside package root (e.g. ../target/..)

Others may want to include something from another folder, including os folders etc?

Start by tracing how cargo-dist resolves and includes glob paths relative to the Cargo.toml directory. Check the existing packaging tests or entry points that handle included files, then define coverage for paths outside the package root. Done means valid external paths can be included without breaking existing package behavior.
