Yes and no.  When the command was originally written there was no such 
thing as a patch release.  When patch releases were added we did not 
update the command to support it.  The reason is that features are not 
supposed to be added on patch levels, and the CMAKE_MINIMUM_REQUIRED 
command is supposed to specify the minimum version providing the 
features used by the project.

I do not see a reason not to add a patch level check because projects 
might work only when a certain bug has been fixed in a patch level. 
Please add this as a feature request in the bug tracker:

and you will be notified automatically of progress.
