-FastCV VPP defaults to `-Dfastcv=auto` (enabled when dependencies are available).
-Use `-Dfastcv=disabled` to disable it or `-Dfastcv=enabled` to require build dependencies.
+FastCV VPP defaults to `-Dfastcv=disabled`. Use `-Dfastcv=auto` to enable it
+when dependencies are available or `-Dfastcv=enabled` to require build dependencies.
+Debian / Ubuntu packages explicitly disable FastCV for consistent distribution builds.
 FastCV is loaded dynamically; missing runtime libraries disable only VPP.
 
 Adjust `libdir` if your system uses a driver directory other than `/usr/lib/dri`.
