# EVIDENCE BUILD -- this is Fedora's rawhide python-cascadio.spec with ONE change: Version
# 0.0.17 -> 0.1.1. OpenCASCADE 8 raised its language baseline to C++17 (it uses std::shared_mutex),
# and cascadio 0.0.17 hardcodes `-std=c++11` (CMakeLists.txt:26), so 0.0.17 does not compile against
# 8.0.1: 509 errors inside OCCT's own headers, e.g. `'shared_mutex' is not a member of 'std'`
# (build mhough/opencascade8-rawhide 11080660). Every tag from 0.0.18rc0 on sets
# CMAKE_CXX_STANDARD 17; 0.1.1 (2026-07-28) is the latest stable and is what PyPI serves.

%global common_description %{expand:
A Python library which uses OpenCASCADE to convert STEP files to a GLB file
which can quickly be loaded by trimesh and other libraries.

This is not intended to be a full binding of OpenCASCADE like OCP or PythonOCC.
Rather it is intended to be an easy minimal way to load boundary representation
files into a triangulated scene in Python. There are a few options for loading
STEP geometry in the open-source ecosystem: GMSH, FreeCAD, etc. However nearly
all of them use OpenCASCADE under the hood as it is pretty much the only
open-source BREP kernel.}
