@seamanm libjsoncpp is part of the webrtc build dependencies. You automatically download it when you run the following commands:

fetch --nohooks webrtc
cd src
git checkout branch-heads/72
gclient sync

As stated in the “Getting Started” section of the ReadMe for the “ffmpeg-wrapper” and “native-to-browser” sub-projects.

If you are trying to get the “sdk-generator” sub-project working, make sure you can find the lib in $BUILD_OBJ_DIR/third_party/jsoncpp/jsoncpp/

Build errors with respect to the WebRTC project itself are beyond the scope of this repository. These should be directed to https://webrtc.googlesource.com/src/
