%description
Viskores (formerly VTK-m) is a toolkit of scientific visualization
algorithms designed for emerging processor architectures with many
integrated cores. It offers a unified data and execution model for
algorithms that can be portably accelerated on multi-core CPUs and GPUs.

This COPR build is configured to interoperate with VTK 9.6+: it uses
VTK-compatible default types (`Viskores_USE_DEFAULT_TYPES_FOR_VTK=ON`)
and matches the build flags VTK's internal-bundled Viskores uses. Once
this package is installed, VTK can be rebuilt with
`-DVTK_MODULE_USE_EXTERNAL_vtkviskores=ON` to drop the bundled copy.

%changelog
* Sun Jun 14 2026 Morgan Hough <morgan.hough@gmail.com> - 1.1.1-1
- Update to 1.1.1 (current upstream; freshness sweep 2026-06-14)

* Tue Jun  2 2026 Morgan Hough <morgan.hough@gmail.com> - 1.1.0-3
- Flip Viskores_USE_64BIT_IDS:BOOL=ON to match VTK 9.6.2's default
  (VTK_USE_64BIT_IDS=ON by upstream default). vtk -11 build 10533571
  failed at compile with `#error VTK was defined with 64-bit ids but
  Viskores with 32-bit ids` because viskores -2 was built with 32-bit.

* Sun May 31 2026 Morgan Hough <morgan.hough@gmail.com> - 1.1.0-2
- Add %%{_libdir}/pkgconfig/viskores.pc to %%files devel. Build 10528870
  compiled cleanly (69 min) but failed the unpackaged-files check.

* Sun May 31 2026 Morgan Hough <morgan.hough@gmail.com> - 1.1.0-1
- Initial standalone packaging of upstream Viskores 1.1.0 for the
  neurofedora COPR. Matches the build flags VTK 9.6.2's internal-bundled
  copy uses (Viskores_USE_DEFAULT_TYPES_FOR_VTK=ON,
  Viskores_USE_DEFAULT_SYMBOL_VISIBILITY=OFF, etc.) so that VTK can be
  rebuilt with -DVTK_MODULE_USE_EXTERNAL_vtkviskores=ON and drop its
  Provides: bundled(viskores).
- OpenMP enabled; CUDA/Kokkos/TBB/MPI/Rendering disabled (deferred —
  separate subpackages if a future consumer needs them, mirroring
  vtk-mpi for MPI variants).
