Summary:                    ExternalProject_Add needs a way to silence progress
output (and progress output is bogus)
Description: 
We're using ExternalProject_Add to help build dependencies, but it can lead to
nearly 3,000 lines of progress output as seen here:
https://travis-ci.org/neovim/neovim/jobs/20601268#L826

It'd be nice if CMake provided a way to disable that output.  Plus, the output
is bogus.  The first output was 100%, then 0%, then 739%, and ending at
3069066%.

Finally, this issue would've been easy to work around had the download, verify,
and extract steps been exposed separately.  Since they're not, it a substantial
amount of work, just to avoid seeing 3,000 lines of progress. :-(
