Unable to build SYCL

# Prerequisites
I am running the latest code. Development is very rapid so there are no tagged versions as of now.
I carefully followed the [README.md](https://github.com/abetlen/llama-cpp-python/blob/main/README.md).
I [searched using keywords relevant to my issue](https://docs.github.com/en/issues/tracking-your-work-with-issues/filtering-and-searching-issues-and-pull-requests) to make sure that I am creating a new issue that is not already open (or closed).
I reviewed the [Discussions](https://github.com/abetlen/llama-cpp-python/discussions), and have a new bug or useful enhancement to share.

# Expected Behavior

After following the steps to install llama_cpp_python + SYCL, the application should work and can run on Intel GPU.

# Current Behavior

Please provide a detailed written description of what `llama-cpp-python` did, instead.

# Environment and Context
