error: library kind `framework` is only supported on Apple targets

error: could not compile `accelerate-src` (lib) due to previous error
warning: build failed, waiting for other jobs to finish...
```

Start in candle-examples/examples/mistral and reproduce the shown cargo run command with the accelerate feature on the reported Windows environment. Inspect why accelerate-src is compiled for this target and determine the expected behavior for the quantized example; done when the command no longer fails with the Apple-target framework error.
