Developed a configurable artifact selection feature for the elixir-nx/emlx repository, focusing on enhancing build automation and downstream integration. The work centered on Makefile scripting, introducing an overridable MLX_SO variable that allows downstream projects to specify custom MLX artifacts without modifying the Makefile directly. This approach improved flexibility for integration scenarios such as iOS static linking, reduced maintenance overhead, and streamlined onboarding for new build targets. By decoupling artifact selection from the top-level Makefile, the solution promoted consistent CI and build processes across platforms, leveraging Makefile and build automation skills to address integration and compatibility challenges within the build system.
