This line is doing an installation (look at the output).

>>$ make

Then you build the software, strange enough to build AFTER installing.

>>$ make package # CPack is configured ...

Then you re-install through CPack and run cpack for building the package.

The first command line "cmake -DCOMPONENT=dist ..." and
the last one "make package" are unrelated.

You should read that:

OK but as far as I know
it is not enough to use COMPONENT and get it work with CPack.
You should:
   1) tell CPACK you want component installer using
      set(CPACK_COMPONENTS_ALL ....)

   2) use a CPack generator that do support COMPONENT installer
      not ALL but a few CPack generator do support COMPONENT.

For example DEB and RPM don't:
http://public.kitware.com/Bug/view.php?id=7645
NSIS does.
TGZ, ZIP ==> I don't know.

What CPack generator are you using? ZIP, TGZ, NSIS, RPM, DEB ??

Yes I think it is but may be you are "only" lacking the COMPONENT
install for you target CPack generator.
