 If no accelerator options are provided and auto-detection finds nothing, `WITH_CPU` is enabled by default.
 
+For Hygon builds, set `DTK_ROOT` to the DTK installation root if it is not installed at `/opt/dtk`. You can override the default DCU arch with `-DHYGON_ARCH=<arch>` when configuring CMake.
