%description
ACVD provides fast, high-quality simplification and isotropic/anisotropic
remeshing of 3D triangular surface meshes, based on Approximated Centroidal
Voronoi Diagrams (Valette et al.). It is built on top of VTK and provides the
vtkSurface and vtkVolumeProcessing shared libraries plus a header-only discrete
remeshing module, used by statistical-shape-modeling pipelines (e.g. ShapeWorks)
for surface correspondence preprocessing.

%build
# ACVD's sources use unqualified cout/cin/cerr/endl with neither <iostream> nor
# `using namespace std` — they relied on transitive availability that newer VTK
# headers / GCC 15 no longer provide. Force-include a small prelude that supplies
# both, restoring the environment the code was written for.

# Library-only build: the bundled Examples produce many generically-named CLI
# binaries (viewer, icp, sampleMesh, ...) that would collide in %{_bindir};
# downstreams (ShapeWorks) need only the libraries + headers + cmake config.
# ACVD uses its own INSTALL_*_DIR vars (not CMAKE_INSTALL_LIBDIR), so set lib64.

* Wed Jun 18 2026 Morgan Hough <morgan.hough@gmail.com> - 4.0-1
- Initial package (stock upstream valette/ACVD v4.0). Library-only build
  (BUILD_EXAMPLES=OFF) against system VTK; provides vtkSurface /
  vtkVolumeProcessing / vtkDiscreteRemeshing for the ShapeWorks dependency chain.
