How could I use a build of whisper.cpp with CUBLAS about whisper

[pkese]

I've tried to get build to work on Linux, but then had a problem of how to cleanly install Ninja and Vcpkg.
So I figured out I'll get more quickly to results with https://github.com/sandrohanea/whisper.net
It has an option to provide my own build of libwhisper.so when loading the library, which fits my purpose.

Otoh, I appreciate the cleanliness of your approach: a c++ like interface with least added ceremony (I could simply read the original c++ source files and know how to use the dotnet version).

Yes, something like #20.

Right now I'm stuck on

nvcc fatal : A single input file is required for a non-link phase when an outputfile is specified

It's the same issue that's described in ggerganov/whisper.cpp#840 but I already have the fix described as the submodule is at a later commit than ggerganov/whisper.cpp#867 🫤

NVlabs/instant-ngp#39

It sounds like something in that nvcc.exe command is misformatted.

I don't have a device to test this on so I'm stuck with a 20 minute or more feedback cycle with GitHub actions. If you have a moment and have a device to test with, it would be helpful if you could try to identify what's wrong with that comand.

Sorry, I wasn't aware this library is Windows only.

The machine with GPU that I intend to run Whisper on is Linux.
I found out only after trying to build this library on Linux.

It's something I'd like to add, #6

You could:

1. Add support for it, starting here
2. Use https://github.com/sandrohanea/whisper.net which already supports linux
   (You'll need to contribute cuBLAS support there, probably publishing another runtime package like is done for CoreML.)
