Bug description:

I'm trying to build Python 3.14 wheels for Android with cibuildwheels@3.2, which newly adds cp314-android support.

However, when I add an extra item to the build matrix (without changing anything else), CMake fails to find the Python Development.Module. Note that everything works fine with Python 3.13 on Android.

- CMake Error at /usr/local/share/cmake-3.31/Modules/FindPackageHandleStandardArgs.cmake:233 (message):
    Could NOT find Python (missing: Development.Module) (found suitable version
    "3.14.0", minimum required is "3.8")
  
        Reason given by package: 
            Development: Cannot find the directory "/tmp/cibw-run-bewfqrm_/cp314-android_arm64_v8a/venv/include/python3.14"

    CMakeLists.txt:261 (find_package)

I found the above directory (i.e., sysconfig.get_path('platinclude')) does not exist in the venv.

The build log diffs between Python 3.13 and Python 3.14 on Android:

This is probably an issue with cibuildwheel, so let's continue in pypa/cibuildwheel#2611.
