Each Rust source file given to a target is considered a separate crate root. There's a concept of a "main crate root", which is the `.rs` file that is given to the final linker phase in CMake. Other Rust source file in a target are built as rlib separately. The project can still build `.rs` files into object files by setting the Rust_EMIT property on the desired source file.
