Makefile output potentially too verbose

[mikebentley15]

Feature Request

Describe the new feature:
Right now, the generated Makefile spits out every gory detail of what is being compiled with the full compilation command. Wouldn't it be nicer if we did something like what CMake does? They do

1. colored output
2. concise output

Suggested change:

• Utilize the color_out.mk file from the tests directory (or something like it).
• Only write brief messages, such as main.cpp -> obj/gt/main.o
• If VERBOSE is set to a value, then go back to the old behavior of barfing out everything

Alternative approaches:
We could skip this feature request, as it is mostly cosmetic.

Another approach could be to copy what is in a CMake autogenerated Makefile.
