 Install the following dependencies:
 - `cargo` (via [rustup](https://rustup.rs/), the version from your package manager is too old)
- - a C compiler (any will do, [the build script](https://docs.rs/cc/latest/cc/#compile-time-requirements) will find it automatically)
- - (on linux) `libasound2-dev` and `libudev-dev`
