[hanson]

I build demo on mac os
step 1:
cmake . -Bbuild
-DLIBWEBRTC_INCLUDE_PATH:PATH=/Users/hanson/webrtc-checkout/src
-DLIBWEBRTC_BINARY_PATH:PATH=/Users/hanson/webrtc-checkout/out/Release/obj
-DOPENSSL_INCLUDE_DIR:PATH=/opt//local/include
-DCMAKE_USE_OPENSSL=ON
step2:
cd build
make

error:

It looks like you did not compile libwebrtc but just reference those dirs.
