# The CSXCAD/openEMS structure viewer: opens the XML a CSXCAD/openEMS script writes and shows geometry, mesh and
# dumps in 3D. Last of the four openEMS packages. Upstream ships no desktop entry; AppCSXCAD.desktop here is
# ours (to offer upstream, see docs/desktop-integration-pattern.md).

# Pin the exact VTK ABI this package was built against. VTK freezes its soname at
# libvtk*.so.1 across all of 9.x, so rpm cannot tell 9.5 from 9.6 from 9.7: a consumer
# built against one installs cleanly against another and fails at LOAD with undefined
# symbols. %%vtk_abi comes from vtk-devel's macros.vtk; the %%build test catches a
# buildroot without it (see 3dslicer-igt.spec for why the check is not at parse time).
Requires:       vtk(abi) = %{?vtk_abi}%{!?vtk_abi:UNSET}

%description
AppCSXCAD displays CSXCAD structure files (the XML that openEMS scripts write
with Write2XML) in a Qt/VTK window: primitives by property, the FDTD mesh,
field dumps, with export to X3D and POV-Ray. python3-CSXCAD's AppCSXCAD_BIN
and the Octave CSXGeomPlot call it.
