Build Error in Kinesis Video Streams WebRTC SDK C when Enabling IoT Core Credentials

[VictorTsokonov]

Issue Description

Environment

• SDK Version: testing release with media storage support #1783
• Operating System: arm64, Debian GNU/Linux 12

Steps

1. Clone the amazon-kinesis-video-streams-webrtc-sdk-c repository.
2. Navigate to ~/amazon-kinesis-video-streams-webrtc-sdk-c/samples/Samples.h.
3. Uncomment the line #define IOT_CORE_ENABLE_CREDENTIALS 1 to enable IoT Core credentials.
4. In amazon-kinesis-video-streams-webrtc-sdk-c/build/ run cmake ..
5. In amazon-kinesis-video-streams-webrtc-sdk-c/build/ run make

Expected Behavior

The project builds successfully without errors.

Commenting the #define IOT_CORE_ENABLE_CREDENTIALS 1 line leads to a successful build.

Additional Context

• Using the robot to publish videos in real-time to Kinesis Video AWS and watching the videos from a website.

Question

How can I resolve this build error when enabling IoT Core credentials in the Amazon Kinesis Video Streams WebRTC SDK C?
