%description
OpenCV, scoped down to just the core and imgproc modules via its own
real -DBUILD_LIST option (per explicit user instruction, after
confirming the full library isn't packaged anywhere on this distro
and that Spectacle itself -- not just a dependency -- unconditionally
hard-requires find_package(OpenCV 4.7 REQUIRED core imgproc) with no
option gate to work around). Scoping to BUILD_LIST=core,imgproc skips
the heavy modules entirely (dnn, videoio, gapi, highgui, calib3d, ml,
stitching, objdetect, features2d, flann, photo, video, and all
language bindings), keeping the dependency footprint and build time
to just what Spectacle actually needs. OpenCV's own build system is
self-contained (bundles vendored 3rdparty fallbacks for most optional
libraries when not found), so zlib is the only real external
dependency for this trimmed module set.

%changelog
* Sun Aug 30 2026 Smech <smechlabs@proton.me> - 4.10.0-1
- Real upstream source (GitHub release tag). Built specifically for
  Spectacle's own unconditional find_package(OpenCV 4.7 REQUIRED core
  imgproc) requirement, scoped to just those two modules via the real
  BUILD_LIST option per explicit user instruction to build the
  trimmed version rather than the full library. %%files is a
  first-pass estimate of OpenCV's standard per-module .so naming and
  include4/cmake config layout; not yet verified against a real build
  log -- this is the largest single source tree built this session
  (95MB tarball even before trimming), expect at least one real-error
  correction round and a long build time.
