安装pyproject.toml-based proj时无法构建llama-cpp-python的wheels

安装llama-cpp-python包时，出现下述问题：

根据下面的链接
https://github.com/abetlen/llama-cpp-python/issues/54

 Building windows wheels for Python 3.10 requires Microsoft Visual Studio 2022.

所以需要新装个VisualStudio 2022 + C++ building tool再重装
去官网下载

必须勾选C++桌面开发（10G+），我只改了IDE（4G+）的路径。

安装好之后，再次输入，即可安装成功

pip install llama-cpp-python
