Temporary blocked after ggml-org/llama.cpp#10890 disabled the support for MSVC build for ARM targets.

Tried to use LLVM (Clang) with both Ninja Generator:

Inspired from https://github.com/ggerganov/llama.cpp/blob/master/cmake/arm64-windows-llvm.cmake and https://github.com/ggerganov/llama.cpp/blob/c05e8c9934f94fde49bc1bc9dc51eed282605150/.github/workflows/build.yml#L668C13-L668C144

But also tried with Visual Studio generator (without success).

It seems that Whisper.cpp doesn't have an ARM build of Windows in their CI: https://github.com/ggerganov/whisper.cpp/blob/2ab2eb5110018a1efd2744b7d4465209cf243e4c/.github/workflows/build.yml#L426C8-L434C26

Build finished but cannot merge yet.
It seems that clang build of whisper.cpp runtime for x86/x64 is deadlocking the tests, reverting to MSVC fixes the issue.

I don't have yet an arm64 host so I cannot test arm64 build to see if it will deadlock as well or not and the new ggml version requires clang.
