FreeBSD build fixes for new CMake, and some other

jsoncpp: normalize rpc to include from jsoncpp/json/ instead of just json/, following the same
	pattern as in shared/agoclient.h
Let root CMake-file resolve jsoncpp details, jsoncpp is used everywhere (via agoclient.h)

Dirs: FreeBSD wants stuff in /usr/local and nowhere else.

Use /usr/local/(include|libs) in all targets, needed for uuid, jsoncpp and more.
