This is a simple project using Thrill as a git submodule via CMake project files.
When cloning this repository, use the --recursive option:
git clone --recursive https://github.com/thrill/tutorial-project.git
If you forgot that, then run git submodule update --init --recursive to get the missing repositories.
For more information, see https://project-thrill.org
