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

  The system library `wayland-client` required by crate `wayland-sys` was not found.
  The file `wayland-client.pc` needs to be installed and the PKG_CONFIG_PATH environment variable must contain its parent directory.
  The PKG_CONFIG_PATH environment variable is not set.

  HINT: if you have installed the library, try setting PKG_CONFIG_PATH to the directory containing `wayland-client.pc`.
