%changelog
* Mon Sep 21 2026 ai-importer <ai-importer@openeuler.org> - 2.15.21-3
- Fix: replace if/else/endif block in CMakeLists.txt with unconditional SOURCE_DIR
- Previous sed patch only removed HOME check but COPR still ran git clone; now bypassed completely
* Mon Sep 21 2026 ai-importer <ai-importer@openeuler.org> - 2.15.21-2
- Bundle mrpt upstream sources as Source1 to avoid offline git clone in COPR
- Remove unavailable BuildRequires (freenect/openni/wx/glfw not needed for core libs)
