Updated textproc/jsoncpp 1.7.7 to 1.8.0
---------------------------------------
  - Require cmake>=3.1
  - @cdunn2001 cdunn2001 released this on 15 Dec 2016 21 commits to
    master since this release
  - Plus some other build-related changes. I don't think there is
    anything functionally different from 1.7.7, or even any binary
    incompatibilities, but the cmake change is significant.
