Cython/C++ package computing Euclidean distance transforms on numpy arrays; builds cleanly from checkout with cibuildwheel, no OpenMP so no gpl_sources job needed. Carries a patch fixing setup.cfg's license_files so the wheel ships the LGPL-3.0-or-later text (upstream's own PyPI wheels currently ship none, per an explicit license_files list that turned off setuptools' default glob).
