# Requires nvidia cuda toolkit repo:
# https://developer.download.nvidia.com/compute/cuda/repos/fedora41/x86_64
# Ideally try and limit this to just the -devel libraries (cuda-libraries-devel, cuda-nvrtc-devel, cuda-driver-devel?)
# ^Except that nvidia doesn't offer meta-packages for those, only per-version..versions.
BuildRequires:  cmake gcc-c++ cuda-toolkit
BuildRequires:  pkgconfig(vapoursynth)

ExclusiveArch: x86_64
