Comment (by michaelld):

 You guys are having way too much fun!  ;)

 Given that jsoncpp requires cmake for building, and is unlikely to not
 require it in the future, I think using the cmake-internal version is the
 way to go. I don't see bootstrapping cmake to build jsoncpp to rebuild
 cmake as something I have time to work on any time soon, even if I wanted
 to, which I don't. I have better things to be doing with my time ;)

 I could see a future where we copy an external jsoncpp into the cmake code
 and use it for building cmake, then relink the cmake binary to instead use
 the already-installer jsoncpp ABI since it would be the same-same as that
 internal. But, again, I have other/better things to be working on.

 Let me know when you're ready to commit.
