Is there some magic that can be added to a dependency entry of Cargo.toml to specify environment variables (e.g., CFLAGS) or other context to be used when building the dependency (and only this dependency)?
Background: this is specifically for a case where a dependency crate is a wrapper/builder for a C-based API/package sqlite (i.e., rusqlite). The as-is crate passes some arguments to the target C compiler that aren't supported.
