Qt6 packages often uses dependencies to cmake package including a version as shown below:

%package devel
Summary:        Qt 6 base development meta package
Requires:       qt6-base-common-devel
Requires:       cmake(Qt6Concurrent) = %{real_version}
Requires:       cmake(Qt6Core) = %{real_version}
Requires:       cmake(Qt6DBus) = %{real_version}
Requires:       cmake(Qt6Gui) = %{real_version}
Requires:       cmake(Qt6Network) = %{real_version}
Requires:       cmake(Qt6OpenGL) = %{real_version}
Requires:       cmake(Qt6OpenGLWidgets) = %{real_version}
Requires:       cmake(Qt6PrintSupport) = %{real_version}
Requires:       cmake(Qt6Sql) = %{real_version}
Requires:       cmake(Qt6Test) = %{real_version}
Requires:       cmake(Qt6Widgets) = %{real_version}
Requires:       cmake(Qt6Xml) = %{real_version}
BuildArch:      noarch

Cmake-related provides generated by the named package do not currently support versions. This means that when porting Qt6 packages to MinGW, the versions would have to be removed manually or via script. It would therefore be helpful if a version were available for these generated "Provides".
