Worked on optimizing the build system for the dosbox-staging/dosbox-staging repository, focusing specifically on MT32 emulation support. Refactored the CMake configuration to ensure the MT32 package is only required when MT32 emulation is enabled, which streamlined the build process and reduced unnecessary dependency resolution for non-MT32 builds. This change improved both build times and CI resource usage, while also clarifying the gating logic for MT32 features within the build scripts. The work demonstrated a strong understanding of CMake and build configuration, resulting in a more maintainable and efficient build system for the project’s evolving requirements.
