Descripción

# Prerequisites

Please answer the following questions for yourself before submitting an issue.

- [x] I am running the latest code. Development is very rapid so there are no tagged versions as of now.
- [x] I carefully followed the [README.md](https://github.com/abetlen/llama-cpp-python/blob/main/README.md).
- [x] 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).
- [x] I reviewed the [Discussions](https://github.com/abetlen/llama-cpp-python/discussions), and have a new bug or useful enhancement to share.

# Expected Behavior

Please provide a detailed written description of what you were trying to do, and what you expected `llama-cpp-python` to do.

# Current Behavior

Building wheels results in error logs (see below).

# Environment and Context

- Docker file, building from `ubuntu:jammy`
- llama-cpp-python versions tested `0.2.88` and `0.3.2`. Behavior consistent.
- Note that I'm still able to build from source directly on my MacOS, so it might be something specific to Linux

# Failure Information (for bugs)

I'm unable to build wheels for `llama-cpp-python` in an `ubuntu:jammy` base Docker image. I get the error: `FileNotFoundError: [Errno 2] No such file or directory: 'ninja'`.

Please help provide information about the failure if this is a bug. If it is not a bug, please remove the rest of this template.

# Steps to Reproduce

Please provide detailed steps for reproducing the issue. We are not sitting in front of your screen, so the more detail the better.

1. `git clone git@github.com:khoj-ai/khoj.git`
2. `cd khoj && docker build .`

You should see the same error reproduced

Here's the `pyproject.toml` it's using to build: [link](https://github.com/khoj-ai/khoj/blob/master/pyproject.toml).

You can see the full error logs [in the GitHub Action workflow](https://github.com/khoj-ai/khoj/actions/runs/11990010386/job/33428489315).

I noticed the ninja project had a release recently, but the error is still consistent if I downgrade ninja to `1.11.1.1`.

Our workflow has been running smoothly, and this is the first time we encountered the error (about two hours ago, ~1:00 PM PST). Any help is much appreciated 🙏🏾.
