# Make the Windows wheels self-contained. cibuildwheel repairs Linux
# (auditwheel) and macOS (delocate) wheels by default, but does
# nothing on Windows. The extension is built with MinGW, so the wheel
# otherwise ships without its runtime DLLs (libstdc++-6.dll,
# libgcc_s_seh-1.dll) and fails to import on a clean Windows Python
# ("DLL load failed while importing _internals"). delvewheel bundles
# them. See https://github.com/inducer/meshpy/issues/150
