Worked on the canonical/mir repository to improve build system reliability and streamline dependency management. Focused on resolving a critical linking issue between the mircommoninput and miral-external components, the developer addressed a missing dependency by updating the CMakeLists.txt to include PkgConfig::XKBCOMMON in the target link libraries. This change, implemented using CMake and pkg-config, resulted in more stable builds and reduced continuous integration failures, benefiting downstream projects and easing onboarding for new contributors. The work demonstrated attention to build configuration details and effective maintenance of multi-target build scripts, contributing to a cleaner and more dependable development workflow.
