- Refactored CMakeLists.txt to streamline project configuration and improve readability.
- Introduced new utility functions in `utils.cmake` for setting compiler flags and managing dependencies.
- Added `dependencies.cmake` to centralize third-party dependency management, enhancing modularity.
- Updated CI workflows to include new build options and improved logging for better feedback during configuration.
- Implemented precompiled headers in various libraries to speed up compilation times.

Benefits:
