@tylerjw Your comments seem to be off topic for this ticket. colcon/colcon-cmake#67 seems to be discussing what you are referring to. Please consider to contribute a pull request to colcon-cmake to implement custom logic to separate the Ninja output.

I'm sorry about that... I'll re-target my comments.
