In February 2025, Steven Loretz modernized the build system for the ros2/ros2cli repository, focusing on maintainability and compatibility with evolving CMake standards. He replaced deprecated ament_target_dependencies with target_link_libraries in CMakeLists.txt, targeting both a specific test fixture and a template used for generating new CMakeLists.txt files. This update improved build clarity and reduced fragility across different environments, making the build process more robust for future development. Steven’s work centered on CMake and build system engineering, enhancing the project’s scaffolding to streamline onboarding and future changes. The depth of the changes addressed long-term maintainability rather than immediate feature expansion.
