c++ - CAP_V4L 不是 cap_.open 中 cv 的成员

Question

我正在尝试用 ros 启动 cv_camera 但我无法在 ros 中编译这个包，我启动了这个命令：

catkin_make --only-pkg-with-deps rossumo cv_camera -DARDRONESDK3_PATH=~/out/arsdk-native/staging/usr
...
/home/docker/catkin_ws/src/cv_camera/src/capture.cpp: In member function ‘void cv_camera::Capture::open(const string&)’:
/home/docker/catkin_ws/src/cv_camera/src/capture.cpp:95:26: error: ‘CAP_V4L’ is not a member of ‘cv’
   cap_.open(device_path, cv::CAP_V4L);
                          ^
make[2]: *** [cv_camera/CMakeFiles/cv_camera.dir/src/capture.cpp.o] Error 1
make[1]: *** [cv_camera/CMakeFiles/cv_camera.dir/all] Error 2

你觉得我做错了什么？

谢谢！
