[wheels] update deploys #7

Description

@Gaspard-Bourgeois
Image En cliquant sur copilot 'explain error" depuis l'onglet action voici ce qu'il me propose : The job failed because CMake could not find the Python3 "Development", "Development.Module", and "Development.Embed" components. Although Python 3.12.10 was detected, its development headers/libraries were missing. This error occurred at line 29 in CMakeLists.txt during the find_package(Python3 ...) step.

Solution:

  1. Ensure the Python development package is installed in your CI environment. For Python 3.12 on Windows, install it with:

    pip install pybind11
    # Make sure the Python dev headers are present.

    Or, for a more robust solution, add the following to your workflow before CMake is invoked:

    - name: Add Python dev headers (Windows)
      run: |
        choco install python --version=3.12.10
        python -m pip install --upgrade pip setuptools wheel
  2. Update your CMakeLists.txt to explicitly require the Development component:

    find_package(Python3 COMPONENTS Interpreter Development REQUIRED)

    If you only need the Interpreter (and not embedding or module development), remove unnecessary components.

  3. If using cibuildwheel or conan, ensure the Python executable used by these tools matches the one with development headers.

Code suggestion for CMakeLists.txt:

find_package(Python3 COMPONENTS Interpreter Development REQUIRED)
# If you need Embed or Module, add them to COMPONENTS

If you need help editing the workflow or diagnosing which Python is being picked up, let me know!

Reference:

  • Error at CMakeLists.txt:29 (view source).
  • Full error: Could NOT find Python3 (missing: Development Development.Module Development.Embed).

Summary:
Install Python development headers and ensure CMake requests the correct components. This will resolve the "Could NOT find Python3" issue and allow the build to proceed.
