Title: Minimize non-error cmake output, unless VERBOSE=1.

For ordinary (non-verbose) build, there's no need to clutter the make/cmake
output with details about every package found. Surround the majority of
non-error cmake messages with if(VERBOSE)/endif().

The whole idea is to make casual users compiling from scratch more easily able to spot errors.
