Cmake: Unable to build on Windows with -DWHISPER_HIPBLAS=ON

[newfla]

Hi,
I'm strugling with windows building using rocm/hipblas feature.
Windows SDK version 10.0.19041.0
Rocm 5.7 for Windows
Is this a known problem? Do you think some configuration might be missing in CMkelists.txt?
My impression is that it's not using hipcc to compile the sources

Logs:

cmake -B build -DWHISPER_HIPBLAS=ON

PS C:\Users\newfl\Downloads\code\whisper.cpp> cmake -B build -DWHISPER_HIPBLAS=ON

Only LLVM is supported for HIP

Seems pretty obvious.

Is there a way to compile under windows enabling rocm?
What I don't understand is why cmake ignores the CMAKE_C_COMPILER/CMAKE_CXX_COMPILER settings. 🤔
