Steps to reproduce issue

colcon build in a workspace with nav2 and slam_toolbox packages

Actual behavior

 CMake Error: Files to be generated by multiple different commands: "<path_to_ws>/build/slam_toolbox/ament_cmake_environment_hooks/library_path.dsv"
 CMake Generate step failed.  Build files cannot be regenerated correctly.
 Failed   <<< slam_toolbox [12.6s, exited with code 1]

Additional information

This setup worked before the latest (2023-03-17) ROS2 rolling synchronization.

the same happens if I first build nav2 alone (skip nav2_bringup dependency on slam_toolbox) and add and attempt to build slam_toolbox afterwards

This is very odd. I'm not sure either. Let me call in backup CC @clalancette

This is likely due to ament/ament_cmake#416. There is more information in there, but you'll likely have to do something similar to moveit/moveit2#1889

Thank you for the note Chris, I'll fix this shortly. That would have taken me much, much longer to try to correlate

@tommy-erko thanks for the report! I've fixed it in #589
