最近opencv-mobile 对luckfox
这款板子进行了适配优化，我对它也很有兴趣所以入手了一个luckfox开发板，包含300万像素摄像头，价格还算比较便宜。
不过官方提供的交叉编译链只有Linux以及windows的，而我却是Mac的，没办法直接调用，刚刚最近在使用bazel，并且它支持远程编译。
关于 luckfox 和 opencv-mobile
可以看看 opencv-mobile 现已支持 luckfox-pico MIPI CSI 摄像头和 rkaiq/rga 硬件加速
关于 Bazel
可以前往官网查看https://bazel.google.cn/
，这里用到的主要是：https://github.com/bazelbuild/bazel-toolchains
开始使用
https://github.com/kekxv/luckfox-bazel做了优化，可以快速使用：

#进入仓库
cd luckfox-bazel
# 如果是 Linux 系统或者wsl，直接编译即可
