Nils Albartus enhanced the build system for the emsec/hal repository by improving OpenMP detection on macOS, specifically targeting developers using Homebrew. He updated the detect_dependencies.cmake script to include a default Homebrew location check and refined the logic for identifying libomp and include directories, ensuring reliable OpenMP integration across Apple platforms. Focusing on build system reliability and cross-platform compatibility, Nils applied his expertise in CMake and dependency management to streamline the developer experience. Although no bugs were fixed during this period, his work delivered a critical feature that improved build robustness and simplified setup for macOS developers working with Homebrew.
