Hm. I fully agree on the problem description, but not entirely sure about this solution. In contrast with Erik, I was more thinking along the lines that the decision to be more quiet could be made by SetupNativeCompilation itself, based on the number of files it compiled. So if it only compiled a single c file into a single dll, then it should be quiet.

With "meta message", I think Erik means that if all tests are suddenly being quiet, we should compensate by printing a more general high-level message like 
"Building NN native tests".
