Issues building airsim_ros_pkgs for ROS 2

Question

What's your question?

I've managed to build this in the past, but apparently something has changed. I'm now getting the following error:

-- Found airsim_interfaces: 0.1.0 (/home/bluecamel/DB/AirSim/ros2/install/airsim_interfaces/share/airsim_interfaces/cmake)
CMake Error at /home/bluecamel/DB/AirSim/ros2/install/airsim_interfaces/share/airsim_interfaces/cmake/ament_cmake_export_targets-extras.cmake:18 (message):
  Failed to find exported target names in

  /home/bluecamel/DB/AirSim/ros2/install/airsim_interfaces/share/airsim_interfaces/cmake/airsim_interfacesConfig.cmake:41 (include)

This happens on clean installs of ros 2 galactic and rolling (using apt) on Ubuntu 20.04.

This issue related to cmake version 3.24. More details here. You can downgrade to older versions.

That did it. Thanks so much!
