Several Issues present when building demo application using steps from: https://github.com/aws/amazon-chime-sdk-cpp/blob/main/chime-sdk-signaling-cpp/demo/cli/README.md

Step 2. branch 4844 includes use of libFuzzer which fails to download. Had to use a newer branch that is no longer dependant on libFuzzer (>6000)

Step 6. Issue with type conversion error: implicit conversion changes signedness: 'int' to 'size_t' (aka 'unsigned long') [-Werror,-Wsign-conversion] 258 | CONF_VALUE *nval = OPENSSL_sk_value((const OPENSSL_STACK *)&cv, j); Changed int j; to size_t j; on line 251 of file chime-sdk-signaling-cpp/build/_deps/libwebsockets-src/lib/tls/openssl/openssl-x509.c and that fixed this problem, but I shouldn't need to be changing code.

Step 7. Issue with protubuf version issue between chime sdk and webrtc. Added target_include_directories(${CLI_NAME} PUBLIC <home_folder>/amazon-chime-sdk-cpp-main/chime-sdk-signaling-cpp/build/_deps/protobuf-src/src/) to end of demo/cli CmakeLists.txt to force it to use the correct protobuf version.

cmake -S . -B build -DCMAKE_TOOLCHAIN_FILE="${TOOLCHAIN_FILE}" runs successfully, but when I run cmake --build build I get the following error: webrtc-build/webrtc/api/peer_connection_interface.h:1569:16: error: no viable conversion from 'rtc::scoped_refptr<VideoTrackSourceInterface>' (aka 'scoped_refptr<webrtc::VideoTrackSourceInterface>') to 'VideoTrackSourceInterface *' 1569 | label, rtc::scoped_refptr<VideoTrackSourceInterface>(source));

I am not sure where to go from here. I believe the issues stem from the guide being quite old, and using an older version of WebRTC, seeing how it refers to using branch 4844 which is 2 years old. Please advise as we would like to move forward with this project using the chime service.

Thanks for your help.
