Oh, just found out that the package `opencl-nvidia` is enough, so I can remove `cuda` completely (instead of 4.6GB of deps, only 22MB!).

Thank you, it showed me that it couldn't find any platform, and I discovered that all I needed was the cuda package.
I can now select GPU acceleration. Well I would have prefered a smaller dependency to have, but at least it now works (cuda takes 4.6 GB once installed).

What is strange tho, is that the AUR package svp-bin does not say cuda is needed (even as a optional dep):

Hello.

In the settings of SVPManager, for some reason I cannot use GPU acceleration.
I have a RTX 3060 laptop, and can use MPV with `--vo=gpu-next` to use it.
Drivers are up to date: nvidia 550.78-2

The web page for "Why GPU accel isn't available?" only speaks about GPU models (and mine should work), but not about any configuration I could have missed.

Anyone knows what I can do?
