The following error occured when trying to run image_publisher: [...]/devel/lib/image_publisher/image_publisher: symbol lookup error: [...]/devel/lib//libimage_publisher.so: undefined symbol: _ZN2cv12VideoCaptureC1Ev Probably, changes in cv_bridge reducing the OpenCV component dependencies led to the error. See ros-perception/vision_opencv@8b5bbcb This is fixed by manually finding OpenCV with the required components and adding the dependencies to the library, not just the node.
