In my point of view, in opencv package , sdk should require -devel not
the inverse
%package sdk
Requires: %{name}-devel
or doc contains the sdk examples :
%package doc
Summary: docs files
Requires: %{name}-devel = %{version}-%{release}
In Virtualbox package, I put part of sdk in devel sub-package and the
other part in pyhton2-%{name}
%files devel
%{_libdir}/virtualbox/sdk
%exclude %{_libdir}/virtualbox/sdk/bindings/xpcom/python
%files -n python2-%{name}
%{_libdir}/virtualbox/*.py*
%{python2_sitelib}/virtualbox
%{python2_sitelib}/vboxapi*
%{_libdir}/virtualbox/VBoxPython2_7.so
%{_libdir}/virtualbox/sdk/bindings/xpcom/python
in resume I do not have any sdk sub-package , and or put that files on
docs or in devel dependent on importance ...
