Worked on the stephenberry/glaze repository to enhance build flexibility and maintainability by generalizing SIMD optimization and improving build configurability. Refactored the CMake build system to replace a fixed AVX2 default with a general SIMD flag and introduced an option to disable SIMD optimizations, supporting a wider range of architectures and compilers. Addressed One Definition Rule violations by converting static constexpr to inline constexpr across multiple headers, preventing linker errors and improving cross-architecture build stability. Utilized C++, CMake, and build system expertise to deliver these changes, focusing on library development and ensuring robust, maintainable builds across diverse development environments.
