As long as it's *possible* to expose the commands, I see nothing wrong
with hiding them by default. I personally almost always use "make -s"
these days, and would not mind if that became the default behavior.
But there had better be a switch to do the other thing.
The other make switch I use all the time is -jN (with varying values of N
depending on what machine I'm on). If cmake can't provide an equivalent
feature, that would be a large minus, because if you have a decent number
of cores -j makes a huge difference in build time.
