After cloning the repo, (e.g., git clone https://github.com/izrik/Ligra.git), the submodules must be setup. The setup-submodules.sh shell script will do it for you automatically, if you're on a unix/linux/macos system.
Once the source and submodules are setup, you can compile with your favorite tool, such as Visual Studio, MonoDevelop, msbuild, or xbuild.
