rust glium compile error missing package on ubuntu

Question

I try compile this in Rust with glium on an Ubutnu machine.

#[macro_use]
extern crate glium;

fn main() {
    println!("Hello, world!");
}

It results in this error:

  --- stderr
  thread 'main' panicked at '`"pkg-config" "--libs" "--cflags" "fontconfig" "fontconfig >= 2.11.1"` did not exit successfully: exit status: 1
  error: could not find system library 'fontconfig' required by the 'servo-fontconfig-sys' crate

  --- stderr
  Package fontconfig was not found in the pkg-config search path.
  Perhaps you should add the directory containing `fontconfig.pc'
  to the PKG_CONFIG_PATH environment variable
  No package 'fontconfig' found

The first error says it cannot find the fontconfig library. What should I do here? How do I get that library installed? I do not know what to do with the second error, either.

OS: Ubuntu 22.04 LTS

I have added glium = "*" to cargo dependencies.

Addendum

The first error is solved after running cargo clean - but the second error still persists. Any ideas?

Using this command in the terminal, install the required dependency:

sudo apt install libfontconfig1-dev
