%description
OpenCV 5 means Intel® Open Source Computer Vision Library. It is a collection of
C functions and a few C++ classes that implement some popular Image Processing
and Computer Vision algorithms.

This is an independent packaging of OpenCV 5.x that installs into versioned
paths (include/opencv5, lib64/cmake/opencv5, libopencv_*.so.5xx) so it can
co-exist with the distribution OpenCV 4.x.

%package        core
Summary:        OpenCV 5 core libraries

This package contains the OpenCV 5 C/C++ core libraries.

Requires:       %{opencv5_devel_requires}
Conflicts:      opencv-devel < 5.0.0
%description    devel
This package contains the OpenCV 5 C/C++ library and header files. It should be
installed if you want to develop programs that will use the OpenCV 5 library.

%package        -n python3-opencv5
Summary:        Python3 bindings for OpenCV 5
Requires:       opencv5-core%{_isa} = %{version}-%{release}
Requires:       python3-numpy
Conflicts:      python3-opencv < 5.0.0
%description    -n python3-opencv5
This package contains Python3 bindings for the OpenCV 5 library. The module is
imported as "cv2". It conflicts with the distribution python3-opencv package,
so only one of the two can be installed at a time.
