To reuse those artifacts with a future compilation, set the environment variable `CARGO_TARGET_DIR` to that path.

I'm not sure I understand the point of using environment variables here. It increases the number of ways that the project can be misconfigured, as this bug demonstrates. If there's concern about unnecessary dependencies, there could just be a crate that has no code and only defines constants that are used by every program.
