[Rust] Including dependencies in the analysis

Hi, is there any way to include cargo dependencies within the generated dbs? Right now im generating it like this

```bash
codeql database create rust-db \
--language=rust \
--source-root . \
--command "cargo build --all-targets --all-features" \
--extractor-option rust.cargo_all_targets=true \
--extractor-option rust.extract_dependencies_as_source=true \
--overwrite
```

But my queries still dont seem to go down into my dependecies
