安装编译环境：

sudo apt update
sudo apt install build-essential cmake

编译：

neardi@LPA3588:~/hailo8/hailo8_yolo5_demo/Apps/yolo$ ./build.sh

编译成功后，拷贝编译生成的可执行文件到Apps/yolo目录，如下：

neardi@LPA3588:~/hailo8/hailo8_yolo5_demo/Apps/yolo$ cp runme.4.14.0 ../../

在Apps/yolo路径，如下运行demo：

neardi@LPA3588:~/hailo8/hailo8_yolo5_demo/Apps/yolo$ ./runme.4.14.0 -b 1 -n "yolov5s" -v "/dev/video22"
