Worked on streamlining the Windows build process for the ros2/rviz repository by removing vendored freetype and zlib libraries. This effort focused on simplifying build system management using CMake, reducing external dependencies, and lowering the maintenance burden for Windows contributors. The changes improved CI stability and resulted in faster build times, making onboarding easier for new developers working on Windows. The approach was validated through continuous integration and cross-review, with input from core contributors. By focusing on build system management and leveraging CMake, the work contributed to a more maintainable and efficient development workflow for the ros2/rviz project.
