Windows - OpenBLAS (CPU) - Could NOT find BLAS (missing: BLAS_LIBRARIES)

I am not able to install llama-cpp-python using

https://github.com/abetlen/llama-cpp-python?tab=readme-ov-file#installation-configuration

`set CMAKE_ARGS="-DGGML_BLAS=ON -DGGML_BLAS_VENDOR=OpenBLAS"`

I get following error

pip install llama-cpp-python --verbose

```

I have tried many different options downloading https://github.com/OpenMathLib/OpenBLAS/releases - [OpenBLAS-0.3.27-x64.zip]

and changed manually llama_cpp_python-0.2.82.tar.gz and path vendor/llama.cpp/ggml/src/CMakeLists.txt

where i have added following in **CMakeLists.txt**

```
include_directories("D:/downloads/OpenBLAS/include")
add_compile_definitions(BLAS_LIBRARIES)
add_link_options("D:/downloads/OpenBLAS/lib/libopenblas.dll.a")
```
But, no luck

tried installing openblas using conda pip install openblas but same error

I have windows 10 Enterprise
Intel i5-1245U / RAM 32 GB

Also refered this - https://github.com/ggerganov/llama.cpp/issues/627 - same error

**I need to use llama-cpp-python with OpenBLAS enabled.**
