# The NVIDIA rungs exist on the desktop only. These features add `ort`'s
# option builders and nothing else — no linking under `alternative-backend` —
# but an Android binary has no business carrying even the option names, and
# the packaging must never be tempted to (§2, §3.1). The AMD rung needs no
# feature: MIGraphX is registered through the runtime's generic key/value
# entry point (`session::migraphx`), because `ort`'s own builder cannot
# name the compiled-program cache.
