@@ -35,8 +35,9 @@ calls ``cibuildwheel`` to build the wheel. The ``cibuildwheel`` is a library tha
suitable Python environment for each OS and processor target. Since we don't have Apple Silion
machine in GitHub Actions, cross-compilation is needed; ``cibuildwheel`` takes care of the complex
task of cross-compiling a Python wheel. (Note that ``cibuildwheel`` will call
``setup.py bdist_wheel``. Since XGBoost has a native library component, ``setup.py`` contains
a glue code to call CMake and a C++ compiler to build the native library on the fly.)
``pip wheel``. Since XGBoost has a native library component, we created a customized build
backend that hooks into ``pip``. The customized backend contains the glue code to compile the native
library on the fly.)
