This is fixed by my next update to the CPack components feature, which
I expect will be merged into CMake CVS after the long weekend. It
implements the macro-based approach to setting up components,
described here:

 http://www.cmake.org/Wiki/CMake:Component_Install_With_CPack#Ideas_for_Future_Development

e.g.,

 cpack_add_component(compname
   DISPLAY_NAME "My Component"
   DEPENDS hiscomp
 )

There's a preliminary version of this patch (which can be applied
against CMake CVS trunk) available here:

 http://public.kitware.com/Bug/view.php?id=6847

But, I won't have the tutorial or examples updated until the patch
goes into CVS.
