The ROCm version of KoboldCpp (https://github.com/YellowRoseCx/koboldcpp-rocm) copies it's runtime libs in a temporary folder called "_MEI" + some nubers, placed in C:\Users\username\AppData\Local\Temp. In those libs there are also hipblas.dll, rocblas.dll, and a "library" folder containing ROCm's tensile library files, and this allows it to run on amd gpus without the need of having the SDK installed.

I just checked, and this works just fine for stablediffussion.cpp too. just copy those libs from koboldcpp's temp folder and place it in the same place as sd.exe

Maybe i can also be a good idea shipping those libs in the rocm windows build
