Worked on the shadPS4 repository to enhance build system reliability by addressing conditional compilation for the optional Discord RPC feature. Focused on C++ development and build systems, the work ensured that the ENABLE_DISCORD_RPC flag correctly included or excluded Discord RPC code, with careful management of include paths to prevent build errors when the feature was disabled. This approach reduced both CI and local build failures, streamlining future maintenance for optional features. By improving the robustness of conditional compilation, the changes supported more predictable builds and minimized the risk of regressions, contributing to a more maintainable codebase for shadPS4.
