irobot_lock_free_events_queue doesn't support symlink-install when building

[nightduck]

Issue was recreated using the steps in Examples except I ran colcon build --symlink-install to build. The result:

Starting >>> irobot_lock_free_events_queue

Would you mind trying this fix? #7

That does fix it
