echo 第1步：检查编译参数[Debug/Release] [x86/arm64]
echo ---------------------------------------------------------------

echo 第2步：设置依赖库路径和输出目录
echo ---------------------------------------------------------------

echo 第4步：清理过期的编译临时文件
echo ---------------------------------------------------------------

echo 第5步：使用gn生成ninja文件
echo ---------------------------------------------------------------

echo 第6步：使用ninja开始编译...
echo ---------------------------------------------------------------

# build
$ninja -C $build_cache_path > $log_path
