▸Build error

Exact error, exit code:
- CMake Error: The source directory "/workspace" does not appear to contain CMakeLists.txt.
- Exit code: 1
- The process failed at: RUN cmake -S . -B build -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/usr

Failing command/step:
- [5/7] RUN cmake -S . -B build -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/usr

Missing packages or files mentioned:
- Missing file: CMakeLists.txt in the workspace directory. The error indicates that the copied source at /workspace does not contain a CMakeLists.txt file.

Version mismatch information:
- Base image shown: Debian oldstable-slim
- Build tools installed during the step include GCC 12 (gcc-12/g++-12) and CMake data (cmake 3.25.1), but there is no explicit version mismatch error reported. No other version mismatch messages are shown beyond the toolchain versions installed.

VERIFYVerifyBuild· step #7

VerifyBuildsmoke_failed

Concerns: The build is conditional on the existence of CMakeLists.txt; if absent, the image will be almost empty (no built libraries). This may be surprising unless the repo guarantees a CMakeLists.txt presence., Using debian:oldstable-slim (deprecated/less-supported) may lead to maintenance issues; consider updating to a current stable-slim tag., Smoke tests assume the library is installed under /usr/local/lib with a libmsgpackc.so name; variations in library filenames (e.g., libmsgpackc.so.1, libmsgpackc.so.5) or different installation paths could cause tests to miss the installed artifact.
Smoke [FAIL]: ls -l /usr/local/lib | grep -i libmsgpack
  Output: 
Smoke [FAIL]: test -f /usr/local/lib/libmsgpackc.so || echo 'libmsgpackc.so not found
  Output: sh: 1: Syntax error: Unterminated quoted string

Concerns: The base image debian:oldstable-slim is outdated; consider using a supported Debian slim tag (e.g., debian:bookworm-slim)., If CMakeLists.txt is not present, the build step yields dummy artifacts, which may mask missing real build logic in CI workflows.
