build [ERROR] - cuda_version must be specified on Windows.

To resolve the "cuda_version must be specified on Windows" error, you need to specify the version of CUDA installed on your system.

You can do this by setting the `cuda_version` parameter in your build configuration. Make sure to provide the correct CUDA version that is installed on your Windows system. Here's an example of how you can do it:

build:
  cuda_version: <your_CUDA_version>

Replace `<your_CUDA_version>` with the version number of CUDA installed on your system, such as `10.1`, `10.2`, or `11.0`.

By specifying the correct CUDA version, the build process should be able to proceed without encountering the "cuda_version must be specified on Windows" error.
