Hello, I'm new to the ROS world and I'm using Kinect V2 to learn more

I tried the solution seen in this comment but the build still gives an error

If you can help me it would be great, I'm using Ubuntu 22.04 and Humble

Hello, thanks for your message, have you installed OpenCV and Cv_bridge? You can try sudo apt install ros-humble-cv* to get all packages related to cv, which should include cv_bridge and then try again

I have installed the packages mentioned but the error still appears

Have you installed the lk4w2 library?
