During July 2025, Piotr Sloboda enhanced the build system of the mariadb-corporation/mariadb-columnstore-engine repository by implementing pkgconf-based discovery for Thrift libraries. He used CMake to enable the build process to locate system-provided Thrift on Fedora-like distributions, while carefully preserving the existing discovery logic to maintain compatibility across environments. This approach reduced reliance on bundled Thrift.cmake, improving portability and simplifying maintenance without introducing risk to established workflows. By aligning the build system with system libraries, Piotr improved CI reliability and cross-distro support. His work demonstrated a strong grasp of build system engineering and cross-platform maintainability using CMake.
