CMake Error: The following variables are used in this project, but they are set to NOTFOUND

Hi everyone,
I am having trouble installing the “NVIDIA Video Codec SDK”. I am using these instructions but can’t get past the following error message:

– Configuring incomplete, errors occurred!

I have the CUDA Toolkit installed and am using it without any issues. Also, I am using OpenCV without any problems. I believe that I fulfill the requirements in the instructions.

System requirements:

  1. I am running an Ampere graphics card (GeForce RTX 3090)
  2. NVIDIA-SMI 465.19.01, Driver Version: 465.19.01
  3. CUDA Version: 11.3
  4. cmake Version 3.16.3

Configuration requrements:

  1. OpenGL is installed and in use with another project
  2. ffmpeg version n4.4
    configuration: --enable-cuda --enable-cuda-nvcc --enable-cuvid --enable-nvenc --enable-shared --disable-static --enable-nonfree --enable-libnpp --extra-cflags=-I/usr/local/cuda/include --extra-ldflags=-L/usr/local/cuda/lib64

What am I missing? Thanks a ton for your advice it’s driving me crazy.
Best,
Alex

yes, I met the same problem now, any one could help? Thanks!
