- Missing packages or files mentioned
  - Package 'cblas', required by 'virtual:world', not found
  - CUDA toolkit not found (CUDA_TOOLKIT_ROOT_DIR not found; CUDA not found or missing components)
    - CUDA_TOOLKIT_ROOT_DIR not found or specified
    - Could NOT find CUDA (missing: CUDA_TOOLKIT_ROOT_DIR CUDA_NVCC_EXECUTABLE CUDA_INCLUDE_DIRS CUDA_CUDART_LIBRARY) (Required is at least version "7.5")
    - Disabling CUDA support for dlib.  DLIB WILL NOT USE CUDA

- Version mismatch / environment details
  - Found PythonInterp: /usr/local/bin/python3 (found version "3.11.15")
  - Found PythonLibs: /usr/local/lib/libpython3.11.so
  - pybind11 v2.3.dev0
  - The build uses GCC 14.2.0 and CMake 3.31.x (e.g., cmake 3.31.6-2)
  - CUDA not available (CUDA support disabled), which may affect dlib’s Python bindings
  - Several deprecation/warning messages related to CMake policies and Python/C++ tooling (e.g., std::iterator deprecation, PyThread/Pybind11 issues with Python 3.11) suggesting potential compatibility issues between pybind11 and Python 3.11.

- Missing packages or files mentioned
  - CUDA toolkit not found: (missing CUDA_TOOLKIT_ROOT_DIR, CUDA_NVCC_EXECUTABLE, CUDA_INCLUDE_DIRS, CUDA_CUDART_LIBRARY) – CUDA not found; DLIB will not use CUDA.
  - CMake warning: Numpy not found (numpy-related functions will throw exceptions).

- Version mismatch / root cause info
  - Base image uses Python 3.11 (python:3.11-slim-bullseye) and Dlib v19.9 with pybind11 bindings.
  - Build errors in dlib Python bindings: invalid use of incomplete type PyFrameObject and related PyThreadState issues, indicating incompatibility between Python 3.11 and this Dlib/pybind11 setup.
  - CUDA not found (logged as missing CUDA toolkit), though not strictly required for a non-CUDA build.

- Note
  - The underlying issue appears to be a Python version compatibility mismatch (Python 3.11 with Dlib v19.9/pybind11) rather than a simple missing package. Upgrading Dlib to a Python 3.11-compatible version or using a compatible Python version (e.g., 3.9/3.10) is likely needed.

- subprocess.CalledProcessError: Command '['cmake', '--build', '.', '--config', 'Release', '--', '-j2']' returned non-zero exit status 2.
- Failing command/step:
  - [3/5] RUN cd /root &&     mkdir -p dlib &&     git clone -b 'v19.9' --single-branch https://github.com/davisking/dlib.git dlib/ &&     cd dlib/ &&     python3 setup.py install --yes USE_AVX_INSTRUCTIONS
- Missing packages/files / warnings:
  - CMake warning: "Numpy not found. Functions that return numpy arrays will throw exceptions!"
  - CUDA not found: "Could NOT find CUDA (missing: CUDA_TOOLKIT_ROOT_DIR CUDA_NVCC_EXECUTABLE CUDA_INCLUDE_DIRS CUDA_CUDART_LIBRARY) (Required is at least version '7.5')"
- Version mismatch / root cause notes:
  - Python 3.11.13 detected: Found PythonInterp: /usr/local/bin/python3
  - dlib version: v19.9 fetched from GitHub
  - pybind11/Python integration errors indicating incompatibility with Python 3.11:
    - error: invalid use of incomplete type ‘PyFrameObject’ (PyFrameObject is forward-declared)
    - PyThreadState_Get()->frame not found (no member named ‘frame’)
  - Overall, the failure is a version-compatibility issue between dlib v19.9, its pybind11 wrapper, and Python 3.11 (CUDA absence is not the root cause)
- Notes:
  - Apt-get install of many libs succeeded (not summarized here)
  - CUDA absence is a warning, not the primary failure

- Missing packages/files mentioned
  - No missing packages or files were reported. The failure is caused by an incorrect here-document syntax in the RUN command, which prevented /root/verify.py from being created.

- Version mismatch information
  - No version mismatch information is present in the log. The base image noted earlier is python:3.10-slim-bullseye, but the error is due to here-document syntax, not a version conflict.

Failing step
- [3/5] RUN pip3 install --upgrade pip setuptools wheel     && pip3 install --prefer-binary dlib==19.24.2

Exact error message and exit code
- Command failed: subprocess.CalledProcessError
- The failed command: 
  Command '['cmake', '/tmp/pip-install-djalw1ty/dlib_a9087fadd76d440caf0c336bf4ea7883/tools/python', '-DCMAKE_LIBRARY_OUTPUT_DIRECTORY=/tmp/pip-install-djalw1ty/dlib_a9087fadd76d440caf0c336bf4ea7883/build/lib.linux-x86_64-cpython-310', '-DPYTHON_EXECUTABLE=/usr/local/bin/python3.10', '-DCMAKE_BUILD_TYPE=Release']' returned non-zero exit status 1.
- Full error tail indicating wheel build failed for dlib:
  "ERROR: Failed building wheel for dlib" and "Failed to build dlib"

Missing packages or files
- No missing system packages/files explicitly reported. The failure is due to a CMake compatibility error during building dlib from source, not a missing file.

Version mismatch / other details
- Core issue: CMake minimum version incompatibility during dlib build
  - "CMake Error at .../dlib/external/pybind11/CMakeLists.txt:8 (cmake_minimum_required):"
  - "Compatibility with CMake < 3.5 has been removed from CMake."
  - "Or, add -DCMAKE_POLICY_VERSION_MINIMUM=3.5 to try configuring anyway."
- This implies the environment’s CMake version does not satisfy the minimum requirement (3.5) for the pybind11/dlib build, causing the wheel build to fail.
