By checking [enable\_language()](https://cmake.org/cmake/help/latest/command/enable_language.html), CMake doesn’t seem to support Rust. What would be the current best way to mix Rust with C project? Especially most of the code is written in C but would like to use a few libraries written in Rust.
Quick search shows me that many projects are using [ExternalProject](https://cmake.org/cmake/help/latest/module/ExternalProject.html#id1).

I suggest using an `add_custom_command` to run `cargo` to make the Rust cdylib. You should be able to make an `INTERFACE` library representing that build then.
