pylon_ros2_camera build failed

[kkuranoCCS]

Describe what you want to implement and what the issue & the steps to reproduce it are:

When I built pylon_ros2_camera, I got the following message and it failed. yaml-cpp has been aleady installed as follows. Please let me know how to solve this problem.

ccsa@ccsa-virtual-machine:~/dev_ws$ colcon build
[0.411s] WARNING:colcon.colcon_core.package_selection:Some selected packages are already built in one or more underlay workspaces:
    'image_transport' is in: /opt/ros/humble
If a package in a merged underlay workspace is overridden and it installs headers, then all packages in the overlay must sort their include directories by workspace order. Failure to do so may result in build failures or undefined behavior at run time.
If the overridden package is used by another package in any underlay, then the overriding package in the overlay must be API and ABI compatible or undefined behavior at run time may occur.

If you understand the risks and want to override a package anyways, add the following to the command line:
    --allow-overriding image_transport

This may be promoted to an error in a future release of colcon-override-check.

  but the target was not found.  Perhaps a find_package() call is missing for
  an IMPORTED target, or an ALIAS target is missing?

CMake Generate step failed.  Build files cannot be regenerated correctly.

Is your camera operational with the Basler pylon Viewer on your platform?

Yes

I solved this problem. After modifying src/pylon_ros2_camera/image_common/camera_calibration_parsers/CMekeLists.txt as follows, the build was successful.

target_link_libraries(${PROJECT_NAME} PRIVATE
  rclcpp::rclcpp
  yaml-cpp)

Thanks.
