--with-metadata false positive with build-dependencies

thanks for making that tool. I'm currently trying to trim unused dependencies, and it has been a great help

running cargo machete --with-metadata on a project with build dependencies doesn't seem to consider anything used inside build.rs

Thanks! I suppose you're asking for something similar to #100? It's not specific to --with-metadata, we don't handle build.rs / build-dependencies at all, as of now. So I'll close as a duplicate. (Please reopen or let me know if you were asking for something different.)

I think it's the opposite in a way, without --with-metadata it doesn't optimize, and with --with-metadata it optimizes "too much", suggesting to remove used dependencies. For instance in https://github.com/quickwit-oss/quickwit/ , --with-metadata suggest removing quickwit_codegen from ./quickwit-ingest/Cargo.toml, where it appears only as a [build-dependencies], and is used in the build.rs.

If it's not supported for now, this issue only half-make-sense anyway.
