qt pro中添加路径
LIBS += /usr/local/lib/libopencv_*

INCLUDEPATH += /usr/local/include \
               /usr/local/include/opencv4 \
               /usr/local/include/opencv4/opencv2

编译失败，没有libcamera\
sudo apt-get install libcamera-dev
在Qt中，pro中添加libcamera.so和libcamera-base.so
并且，qt和libcamera不兼容，需要增加qmake CONFIG+=no_keywords
或者，在libcamera的头文件中，添加#undef signals ,#undef slots,#undef emit,#undef foreach
