I think you can put this in the "real" directory in src/third_party/jsoncpp. The
only reason to use the secondary tree at this point is for things DEPSed in.

Ah, of course. I didn't think about that there was a directory in Chrome and
that just most of the source was pulled via DEPS.

You can delete this line. Direct dependent configs also apply to the current
target.

Done.
