%description
vtkAddon provides general-purpose VTK extension classes that may be
integrated into VTK library in the future. These include spline generators,
oriented transforms, streaming volume codecs, and other utilities used by
3D Slicer and related applications.

%description -n python3-vtkAddon
VTK Python wrapper (vtkAddonPython) for the vtkAddon classes. Required by
3D Slicer's Python environment, whose bin/Python/vtkAddon.py does
"from vtkAddonPython import *".

%changelog
* Wed Jun 17 2026 Morgan Hough <morgan.hough@gmail.com> - 0.1.0-0.3.20260603git1407f010
- Bump to master 1407f010: the previous pin (2ed3e222, Dec 2025) predates
  install(EXPORT vtkAddonTargets), so vtkAddonTargets.cmake was never shipped
  and consumers that include() it (IGSIO) failed. Master ships it; also closer
  to the packaged Slicer commit. Unblocks the SlicerIGT (igsio) chain.
* Sat Jun 13 2026 Morgan Hough <morgan.hough@gmail.com> - 0.1.0-0.2.20251224git2ed3e222
- Fix 3D Slicer bug #9c: build the VTK Python wrapper. Enable
  vtkAddon_WRAP_PYTHON (vtkMacroKitPythonWrap) and ship vtkAddonPython.so in a
  new python3-vtkAddon subpackage, installed into %{python3_sitearch}. Slicer's
  bin/Python/vtkAddon.py does "from vtkAddonPython import *"; in a non-superbuild
  RPM Slicer doesn't wrap the external vtkAddon, so the module never existed and
  "import vtkAddon" failed. sitearch is already on Slicer's embedded sys.path.

* Wed Mar 04 2026 Morgan Hough <morgan.hough@gmail.com> - 0.1.0-0.1.20251224git2ed3e22
- Initial package (git snapshot for VTK 9.6 compatibility)
- VTK extension classes for 3D Slicer
