You need to install ROS 1.

It looks like rosbag2_bag_v2_plugins is looking for its dependency roscpp

This means that you don't have ROS 1 (properly) installed. As is mentioned is a requirement here.

If you install rosbag2_bag_v2_plugins from the bloomed debian package like ros-humble-rosbag2-bag-v2-plugins (on Ubuntu), it will automatically install what you need from ros-noetic-*. But since you are doing it from source, and since rosdep can't help you, you need to install ROS 1 manually as as a separate step.
