LLVM 22 MacPorts CMake setup

The article provides a CMake setup configuration for LLVM 22 on macOS using MacPorts, including a `toolchain.cmake` file that specifies the LLVM 22 compiler path, C++23 standard, and required include/link directories. It also includes `launch.json` and `tasks.json` configurations for debugging and building projects with LLDB and CMake tasks in VS Code.
