Worked on enhancing the build system for the byrnHDF/hdf5 repository, focusing on improving reliability and portability across diverse environments. Addressed issues related to dynamic library path resolution, ensuring correct handling of lib versus lib64 directory layouts and accurate discovery of settings and pkgconfig files. Refined the behavior of the h5cc compiler wrapper to eliminate redundant arguments and provide clearer diagnostics, reducing build-time confusion for developers. Leveraged skills in Shell scripting, CMake, and build systems to deliver these improvements. The work resulted in a more robust build configuration process, supporting both development and deployment in varied system environments.
