How to set NSConstraintBasedLayoutVisualizeMutuallyExclusiveConstraints?

Question

I am getting the following message from Cocoa Auto Layout mechanism:

Set the NSUserDefault NSConstraintBasedLayoutVisualizeMutuallyExclusiveConstraints to YES to have -[NSWindow visualizeConstraints:] automatically called when this happens.

But I don't know how to "Set the NSUserDefault NSConstraintBasedLayoutVisualizeMutuallyExclusiveConstraints to YES".

How do I set this?
