Don't rely on .gitmodules, instead parse the dependencies.yaml file from every subdirectory with a CMakeLists.txt, and sort all projects based on that data. Projects with no dependencies are added last. This allows us to get rid of the duplication of dependency information in .gitmodules, and makes each module the authoritative source of its own dependencies.
