CMake configure step should list all ROS2 message packages found

[mikaelarguedas]

Currently it prints only the output of find_package so if dependencies are found during the process they are not listed.

We should instead find_package the ROS 2 packages with QUIET and then print the full list of packages found.

From nightlies:

-- Found composition: 0.4.0 (/home/rosbuild/ci_scripts/ws/install/share/composition/cmake)
-- Found stereo_msgs: 0.4.0 (/home/rosbuild/ci_scripts/ws/install/share/stereo_msgs/cmake)
-- Found lifecycle_msgs: 0.4.0 (/home/rosbuild/ci_scripts/ws/install/share/lifecycle_msgs/cmake)
-- Found visualization_msgs: 0.4.0 (/home/rosbuild/ci_scripts/ws/install/share/visualization_msgs/cmake)
-- Found example_interfaces: 0.4.0 (/home/rosbuild/ci_scripts/ws/install/share/example_interfaces/cmake)

As an example: sensor_msgs is not in the list

But we actually build factories for it:
