Use build.rs to setup enviroment

Question

I have a project where a dependency requires libclang on the system to build, I want to avoid needing to manually install this on the system and instead use build.rs to automatically download this. Is there a way to run build.rs before dependencies to effectively setup the required environment?

My attempt project:

---

Cargo.toml:

[package]
name = "testing-lib"
version = "0.1.0"
edition = "2021"

# See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html

[dependencies]
userfaultfd-sys = "0.4.1"

lib.rs:

#[cfg(test)]
mod tests {
    #[test]
    fn it_works() {
        let result = 2 + 2;
        assert_eq!(result, 4);
    }
}

build.rs

fn main() {
    std::process::Command::new("sudo").args(["apt","install","clang"]).output().unwrap();
}

cargo build leads to:

error: failed to run custom build command for `userfaultfd-sys v0.4.1`

Caused by:

Is this something that would need to be addressed within the dependency crate? (requiring a change to userfaultfd-sys where if libclang is not found on a system it builds via another approach)
