I am working on with ROS-Melodic and its cv_bridge package needs openCV3.2 version, that’s why I cannot make catkin build -j4 my_package_name , it gives me error like :

When I search about the issue, I saw that could be openCV version confusion , to understand the which CV version that I have fistrly I got from terminal like:
dpkg -l | grep opencv

then in another terminal:

If I understood right, I have three version of openCV but I don’t know which one is using from where?
4.4 for what and If I have 3.2 why I cannot make catkin build? and what about 4.1 version, could you explain as simple as possible, because I am newbie about which version is using where and their purpose etc.
