- Exact error message and exit code
  - CMake Error: The source directory "/workspace" does not appear to contain CMakeLists.txt.
  - Specify --help for usage, or press the help button on the CMake GUI.
  - Exit code: 1

- Failing command/step
  - Builder step: [builder 5/5]
  - Command:
    RUN BUILD_CORES=$(nproc)     && cmake -S . -B build -DCMAKE_BUILD_TYPE=Release     && cmake --build build -j $BUILD_CORES

- Missing packages or files mentioned
  - Missing file: CMakeLists.txt not found in the source directory "/workspace".
  - Context: The step COPY . . populated /workspace earlier, so the error implies the repository lacks a CMakeLists.txt at the project root.

- Version mismatch info
  - No version mismatch reported as part of this error.
  - The build environment uses Ubuntu 22.04 (Jammy) with CMake installed as part of a large apt-get install; but the failure is due to a missing CMakeLists.txt, not a version issue.
