 The preset selects which components and ggml backend are compiled.
 
+On x86_64 hosts, CPU presets disable ggml's native-architecture optimization
+by default so portable artifacts do not require instruction sets from the build
+host. On other architectures, the preset keeps ggml's normal defaults so that
+architecture-specific kernels remain available. Pass `-DGGML_NATIVE=ON` or
+`-DGGML_NATIVE=OFF` explicitly when the target requires a different choice.

 Additional CMake definitions can follow the preset:
