   - `--workers <number>`: override the default worker count mentioned as a target property. This option is **ignored** unless the runtime crate has been built with the feature `parallel-runtime`.
   - `--export-graph`: export the dependency graph (corresponds to `export-dependency-graph` target property). This is a flag, i.e., absent means false, present means true. This means the value of the target property is ignored and not used as default.
