I don't think this needs to be done very often, and is not worth making a
change in CMake for... (So I don't want a patch for it... thanks, anyway)
You can easily edit the custom command that CMake already generates for
running CPack directly in the Visual Studio gui if you need to add command
line arguments for debugging purposes.

Simply right click the "PACKAGE" project, and choose "Properties" -- when
the property pages come up, look for "Build Events" and "Post-Build Event"
and edit the command line for the post build event.

You can see there's one line in there that calls cpack with something like:

  "C:\Program Files (x86)\CMake 2.8\bin\cpack.exe" -C $(Configuration)
--config ./CPackConfig.cmake

Just add your --verbose and --debug there, and then right click the
"PACKAGE" project again, and choose "Project Only > Build Only PACKAGE" to
execute the post build command that you just edited...


Alternatively, besides some environment differences (which may but don't
typically cause final package differences), there should be no reason you
can't just run cpack directly from a command prompt in your build tree and
get the exact same package.


HTH,
David
