添加calib3d模块的opencv-mobile编译方法

3

感谢大佬提供的移动端opencv库，本人需要用到人脸检测矫正函数，所以需要添加calib3d模块，但是calib3d默认使用了rtti选项，这里通过一个死方法，打开了rtti选项才将calib3d模块成功添加后才编译通过，模型有点大；ncnn也必须开启rtti，才能同时使用ncnn和opencv。这里是具体的解决办法 [开启rtti选项源码编译android的ncnn库](https://blog.wangjui.com/article/113)，有时间准备改改calib3d的源码把rtti去掉，不过也期望大佬能够改改calib3d的源码把使用到rtti的源码去掉

请问这个 `/dev/mpi/valloc` 是 luckfox-pico 特有的吗？ 我尝试在我的 firefly roc-rk3588s-pc 上编译使用， 后来发现我的板子上没有这个文件？ 如果没有这个文件，那我要做 mmap 的话，是否有其他的一些方法？
