- Split monolithic 235-line CMakeLists.txt into focused modules - Main file reduced to 78 lines with clear section organization - Created 5 specialized modules: * ZstdVersion.cmake - CMake policies and version management * ZstdOptions.cmake - Build options and platform configuration * ZstdDependencies.cmake - External dependency management * ZstdBuild.cmake - Build targets and validation * ZstdPackage.cmake - Package configuration generation Benefits: - Improved readability and maintainability - Better separation of concerns - Easier debugging and modification - Preserved 100% backward compatibility - All existing build options and targets unchanged The refactored build system passes all tests and maintains identical functionality while being much easier to understand and maintain.
