I am using a Rust dependency which allows being built with a --debug or --verbose flag.
I am running my test as follows:
cargo test --package mw-btc-swap --bin mw-btc-swap -- grin::grin_core::test::test_fin_tx --exact --nocapture
Now my question is how can I configure cargo to only compile this specific dependency with the desired flag. I tried using RUSTFLAGS=--debug environment variable but then the flag seems to be passed to all compilations which makes most of them fail, as they don't support this flag.
I have also looked through https://doc.rust-lang.org/cargo/reference/specifying-dependencies.html in hope I could somehow specify the flags in the cargo.toml which doesn't seem to be the case.
