CUDA requirements need to match project dependencies. Distribute the libraries? about whisper-writer

I also had problems with getting CUDA to run. WhisperWriter told me CUDA not available. I had CUDA 12.1 and CUDNN 9.0 installed.

Later in the process, I noticed that the PATH contained C:\Program Files\NVIDIA\CUDNN\v9.0\bin, although the DLLs are in an additional subfolder that's named after the CUDA version. Someone having problems could first try to change the PATH directory to the subfolder for the respective CUDA version and see if that helps.

Anyways, I did the following and now WhisperWriter works for me:

• Installed CUDA 11.8 from here
• Ran the command from the command creator here for CUDA 11.8
• Downloaded CUDNN v8 for CUDA v11 from here (required me to make an account with e-mail and password)
• Copied the CUDNN DLLs similarly to what's officially described on https://docs.nvidia.com/deeplearning/cudnn/installation/windows.html#installing-on-windows and updated the PATH. I used the path C:\Program Files\NVIDIA\CUDNN\v8.9\bin\11.8 for the DLLs.
• Made sure the CUDA- and CUDNN-related environment variables had the correct versions and paths in them. (Note that processes inherit the set of env vars from the parent process and don't auto-update, meaning: restart the process tree from a certain point.)

EDIT: After restarting, WhisperWriter complained that a DLL belonging to CUDA v12 was missing. I then added the two v12.3 paths I still had installed to my PATH environment variable additionally to the v11.8 paths and it worked again (i.e., C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v12.3\bin and C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v12.3\libnvvp).
