Admittedly, we are solving someone else's problem, but the header is
buried inside the SDK download which is hidden behind a click-through on
nvidia's web page. So it's not made available in a way that is readily
consumable by an end user or by a distribution vendor.
With the new licencing, a distro vendor *could* take the header and
it up themselves, but that's the sort of them that's exceptionally hard
convince them to do.
And in the case of windows (where nvenc works too), there is no distro
and nvidia certainly won't make the header more accessible than it
If the goal is to make the feature as available as possible to as many
as possible, then this is the way to do it.
