%description
Axom is a collection of robust and flexible software components that serve as
building blocks for high-performance computing applications, developed as part
of the LLNL RADIUSS stack. Components include core, slic, slam, primal, mint,
spin, sidre, inlet, klee, and quest.

# does ship MFEMConfig.cmake, so axom finds `mfem` as a real IMPORTED target and
# blt_patch_target (BLT 0.7.2) picks PUBLIC scope, which CMake forbids on
# imported targets ("IMPORTED library can only be used with the INTERFACE
# keyword"). Use the one form CMake allows; it achieves the same propagation.

%changelog
* Thu Oct 08 2026 Morgan Hough <morgan.hough@gmail.com> - 0.15.0-4
- Rebuild against mfem 4.10-1.1 (soname libmfem.so.4.10.0)

* Thu Oct 08 2026 Morgan Hough <morgan.hough@gmail.com> - 0.15.0-3
- Build against compat-lua (Lua 5.1) on Fedora 45+, where Lua is 5.5: the bundled sol2
  rejects LUA_VERSION_NUM > 504 (COPR 11092263 failed on f45/rawhide with sol.hpp:2369 #error).
  Fedora 44 keeps the system Lua 5.4; the -devel subpackages require the matching Lua -devel.

* Wed Oct 07 2026 Morgan Hough <morgan.hough@gmail.com> - 0.15.0-2
- Rebuild against camp 2026.07.2, RAJA 2026.07.1 and conduit 0.9.9

* Sat Aug 29 2026 Morgan Hough <morgan.hough@gmail.com> - 0.15.0-1
- Update to 0.15.0 (RADIUSS 2026.07 wave). First release containing the
  smith-pinned f81109ce (Lua 5.4 sol2), so drop the commit snapshot and
  return to a clean release tag.

* Wed Jul 01 2026 Morgan Hough <morgan.hough@gmail.com> - 0.14.0-5
- Enable MFEM sidre DataCollection (MFEMSidreDataCollection.hpp), required by smith

* Tue Jun 30 2026 Morgan Hough <morgan.hough@gmail.com> - 0.14.0-4
- Switch to smith's pinned axom commit (f81109ce) for Lua 5.4-compatible sol2

* Tue Jun 30 2026 Morgan Hough <morgan.hough@gmail.com> - 0.14.0-3
- Enable Lua (inlet LuaReader + bundled sol2), required by LLNL/smith

* Mon Jun 29 2026 Morgan Hough <morgan.hough@gmail.com> - 0.14.0-2
- Add MPICH and OpenMPI variants (Fedora-correct MPI subpackages)

* Sun Jun 28 2026 Morgan Hough <morgan.hough@gmail.com> - 0.14.0-1
- Initial package (RADIUSS dependency stack for LLNL/smith)
