ROS Noetic Ubuntu 20.04

When I include cv_bridge like this:

#include <cv_bridge/cv_bridge.h>

and then use:

catkin build <project_name>

I get this error:

/opt/ros/noetic/include/cv_bridge/cv_bridge.h:43:10: fatal error: opencv2/core/core.hpp: No such file or directory
   43 | #include <opencv2/core/core.hpp>

I installed the full version of Noetic.

Is there a way to fix this?

Am I missing any additional things in my CMake or xml file? All that I have added is the following:

  <build_depend>cv_bridge</build_depend>

target_link_libraries(Color ${catkin_LIBRARIES}
                        ${OpenCV_INCLUDE_DIRS})

As far asmy knowledge goed, Noetic comes with OpenCV4, while cv_bridge is trying to include Opencv2

Yes you are correct. I was missing it in find_package. My bad. Although, im not sure if it should be added to catkin_pac

Command for building is catking build <project_name>. The error logs is very similar to this one: https://github.
