During November 2024, Giang Bui focused on improving the build system for the 4C-multiphysics/4C repository by addressing issues with static library header installation. Giang implemented targeted changes in CMake, introducing conditional installation logic to ensure header files were correctly exported in static library configurations. This adjustment enhanced build reliability and reduced integration issues for downstream users. By leveraging expertise in build system configuration and CMake scripting, Giang resolved a persistent bug that previously caused build failures. The work demonstrated a methodical approach to stabilizing the build process, resulting in more consistent and maintainable static library builds for the project.
