Worked on the nextcloud/desktop repository to enhance build system reliability by addressing compatibility issues related to WebEngine-disabled configurations. Focused on C++ development, the work involved modifying the error display logic to conditionally include the Page_WebView component only when WebEngine was enabled. This targeted bug fix prevented compilation errors in environments lacking WebEngine support, thereby reducing CI failures and improving the stability of multi-configuration releases. Updates to documentation and commit notes ensured future maintainers could easily understand the changes. The approach demonstrated careful attention to build system nuances and contributed to more robust cross-configuration support within the C++ codebase.
