Worked on the antmicro/verilator repository to stabilize the build configuration by ensuring that the default CMAKE_BUILD_TYPE is set to 'Release' when not explicitly specified. This approach improved the reproducibility of release builds and reduced variability in build artifacts across different environments. The work focused on CMake for build system configuration, emphasizing production-oriented build strategies and consistent optimization. Additionally, the CONTRIBUTORS file was updated to reflect accurate contributor attribution. By centralizing the default build type within the CMake configuration, the groundwork was established for future enhancements to the build process, supporting maintainable and reliable software delivery practices.
