Use -Wno-undef to compile jsoncpp.

This should fix this error:
In file included from ../../api/audio/echo_canceller3_config_json.cc:19:
In file included from ../..\rtc_base/strings/json.h:18:
In file included from ../../third_party/jsoncpp/source/include\json/json.h:9:
In file included from ../../third_party/jsoncpp/source/include\json/autolink.h:9:
../../third_party/jsoncpp/source/include\json/config.h(126,5): error: '__GNUC__' is not defined, evaluates to 0 [-Werror,-Wundef]

Maybe we could also fix it upstream.

WebRTC is a free, open software project that provides browsers and mobile applications with Real-Time Communications (RTC) capabilities via simple APIs. The WebRTC components have been optimized to best serve this purpose.

Our mission: To enable rich, high-quality RTC applications to be developed for the browser, mobile platforms, and IoT devices, and allow them all to communicate via a common set of protocols.

The WebRTC initiative is a project supported by Google, Mozilla and Opera, amongst others.

Development

See http://www.webrtc.org/native-code/development for instructions on how to get started developing with the native code.

Authoritative list of directories that contain the native API header files.
