# --- BEGIN ANDROID CROSS-COMPILATION FIX ---
# Buildozer/python-for-android uses standard pip install which doesn't natively
# pass a CMake toolchain file to scikit-build-core. This detects the Android compiler
# from the environment and forces CMake into cross-compilation mode to prevent
# it from building host (x86_64) binaries.
