While libcosmic is written entirely in Rust, some of its dependencies may require shared system library headers to be installed. On Pop!_OS, the following dependencies are all that's necessary compile a typical COSMIC project:

sudo apt install cargo cmake just libexpat1-dev libfontconfig-dev libfreetype-dev libxkbcommon-dev pkgconf

Some examples are included in the examples directory to to kickstart your COSMIC adventure. To run them, you need to clone the repository with the following commands:

git clone https://github.com/pop-os/libcosmic
cd libcosmic

If you have already cloned the repository, run these to sync with the latest updates:

git fetch origin
git checkout master
git reset --hard origin/master

The examples may then be run by their cargo project names, such as just run application.
