Is ROCM backend build for Windows is actually usable?

[DalekoDaleko]

I am having troubles running ROCM backend build with AMD Radeon RX 7900 XTX.
After some troubleshooting, I have a suspicion, that the backend package isn't actually targeting the correct platform.
Here is why I suspect so:

StableDiffusion.NET/.github/workflows/backends.yml

Line 153 in 9fd65e1

cmake -G "Unix Makefiles" .. -DCMAKE_C_COMPILER="${env:HIP_PATH}\bin\clang.exe" -DCMAKE_CXX_COMPILER="${env:HIP_PATH}\bin\clang++.exe" -DGGML_HIP=ON -DCMAKE_BUILD_TYPE=Release -DAMDGPU_TARGETS="gfx1100;gfx1101;gfx1030" -DGGML_RPC=ON -DSD_BUILD_SHARED_LIBS=ON

has -DGGML_HIP=ON -DAMDGPU_TARGETS="gfx1100;gfx1101;gfx1030" preprocessor directives set.
Where as instruction is https://github.com/leejet/stable-diffusion.cpp/blob/636d3cb6ff25d1ffa7267e5f6dac9f2925945606/docs/hipBLAS_on_Windows.md and the respective source code use
-DSD_HIPBLAS=ON -DAMDGPU_TARGETS=gfx1100
and GGML_HIP is only referenced in https://github.com/leejet/ggml/blob/83835ffaa0f2e68bc8530bd0a7584711789dc23b/README.md.

Specifically, when running with Windows rocm backend I could see that the correct backend library is loaded from the rocm subfolder. But it always defaults to CPU backend as if there was no other backend option enabled in the code.

P.S. I see that Linux build is using a different, possibly correct set of defines.

I am very much certain that the ROCKM package is incomplete due to its incorrect build settings for Windows.
As a workaround which seems to work, one could unzip the content of sd-master-636d3cb-bin-win-rocm-x64.zip from https://github.com/leejet/stable-diffusion.cpp/releases into runtimes\win-x64\native\rocm6 and that seems to do the trick for now.
