chore(cmake): update .gitignore and enhance CMake configuration

- Added new entries to .gitignore to exclude generated files and directories, improving project cleanliness.
- Set minimum policy version for subdirectories in CMake to ensure compatibility with older dependencies like yaml-cpp, enhancing build reliability.

Benefits:
- Streamlined project structure by ignoring unnecessary files.
- Improved compatibility and maintainability of the CMake configuration.
