该程序本人是在Ubuntu18.04 Jetson Nano上运行的，前面编译都很顺利，但是最后一步opencv_demo编译失败。

make[1]: Entering directory '/home/nano/apriltag-master/example'
opencv_demo.o
opencv_demo.cc:30:10: fatal error: opencv2/opencv.hpp: No such file or directory
#include "opencv2/opencv.hpp"
^~~~~~~~~~~~~~~~~~~~
compilation terminated.
Makefile:27: recipe for target 'opencv_demo.o' failed

跪求各位大佬解答
