You can call a compiler for C/C++ from build.rs. That tooling is currently not very advanced. As far as I know there is no crate to write compile recipes that as easily as a Makefile or CMakeLists.txt. When I tried this in build.rs, I had to check modification times myself. There is an opening for a ninja-type crate in Rust.
