%description
SlicerExecutionModel is a CMake-based project that provides macros and
associated tools allowing to easily build 3D Slicer CLI (Command Line
Interface) modules. These are self-describing executables that automatically
generate XML descriptions of their command-line arguments, which 3D Slicer
uses to construct graphical user interfaces.

%changelog
* Tue May 05 2026 Morgan Hough <morgan.hough@gmail.com> - 2.0.0-0.4.20260301git3bd8e038
- Fix %%files: cmake configs install to /usr/lib/ (not %%{_libdir}=/usr/lib64/),
  drop nonexistent tclap install dirs (tclap is header-only bundled, not exported)

* Tue May 05 2026 Morgan Hough <morgan.hough@gmail.com> - 2.0.0-0.3.20260301git3bd8e038
- Append explicit configure_file blocks to GenerateGenerateCLPConfig.cmake
  for GenerateCLPConfig.cmake_install and UseGenerateCLP.cmake_install
  (upstream's CMakeLists installs these files but never produces them)

* Mon May 04 2026 Morgan Hough <morgan.hough@gmail.com> - 2.0.0-0.2.20260301git3bd8e038
- Extend configure_file uncomment to GenerateCLP/Generate*Config.cmake
  (fixes "file INSTALL cannot find GenerateCLPConfig.cmake_install")

* Wed Mar 04 2026 Morgan Hough <morgan.hough@gmail.com> - 2.0.0-0.1.20260301git3bd8e038
- Initial package (git snapshot)
- Uses system ITK 5.4.x from COPR
- Bundled tclap (Slicer-modified version)
