Yeah, I figured if anyone ever actually needed to turn this on for debug builds 
in general, they'd have added that option. It seemed to me like this is more 
just some convenience thing for whoever was working on that code. I didn't want 
to couple this to `NDEBUG` or some external function like the other stuff does 
since this output so far wasn't turned on that way either. And adding a whole 
CMake build option just for this seemed like overkill. Given the way it's been 
used so far, doing it via a CMake option would likely get in the way more than 
anything else since that would force a wider rebuild every time you switch. So 
I just kept the overall behavior as-is. With the macro in the config header 
now, it will be trivial to add a build flag or something, should the need ever 
arise.
