Unable to build S3 example using provided instructions

提供された Dockerfile と S3 example のビルド手順から始め、make で失敗を再現して、関連する CMake ビルド構成を調査します。動作するビルドプロセスを反映するように手順を更新し、文書化された手順から S3 example が正常にビルドできることを確認します。

The instructions say to use the provided Dockerfile to build the S3 example. However, it looks like something has changed as the build now fails:
