Building llama.cpp with vulkan on openSUSE

When trying to run llama.cpp locally, I found that the instructions for building the docker image with vulkan acceleration doesn't work on my openSUSE Tumbleweed machine.

Instead, I needed to build and run the client directly on my host machine.

First, make sure both "vulkan-devel" and "shaderc" packages are installed.

Next, build it with vulkan

git clone https://github.com/ggerganov/llama.cpp
cd llama.cpp
mkdir build
cd build
cmake .. -DGGML_VULKAN=on -DCMAKE_BUILD_TYPE=Release
make

The client should detect and use GPU via vulkan library.
