[ ] Update versions in the CMake files of each project that received changes since the previous release. In case nothing changed since the last release, the version should be same! Make sure to check the projects a project depends on! Changing a child-project may imply a change in the parent project.
[ ] Tag each project that received changes since the previous release with a project-specific version. In case the version in a project's CMake file changed, than the project needs to be tagged. Otherwise it should not.
