Worked on stabilizing Windows builds for the nextcloud/craft-blueprints-kde repository, focusing on build system configuration and cross-platform development using Python. Addressed a persistent MSVC compilation issue by re-enabling KItinerary in kdepim-addons, which restored Windows build functionality, and by disabling frei0r-plugins to prevent further build failures. These targeted changes improved the reliability of both master and stable CI pipelines, reducing flaky builds and enabling more predictable release cycles. The work laid a foundation for faster iteration on Windows platforms, emphasizing careful dependency management and robust build processes to support ongoing development and maintenance across multiple environments.
