During March 2025, Hefee worked on the nextcloud/desktop repository, focusing on improving build system reliability for C++ projects with varying WebEngine dependencies. Hefee addressed a compilation issue that occurred when WebEngine was disabled by conditionally including the Page_WebView logic only when the feature was enabled. This targeted bug fix stabilized builds across multiple configurations, reducing CI failures and supporting environments without WebEngine. Hefee updated documentation and commit notes to clarify the new compatibility, streamlining future maintenance. The work demonstrated a solid understanding of C++ development and build systems, with careful attention to cross-configuration stability and maintainability in collaborative projects.
