You are right, my proposal does not take this into account.

But I'm afraid this is an issue I did not think about for now.
My CURRENT point of view is that CPack may generate
two "simple" kind of package

  - binary which basically packages the result of a "make install"
  - source which basically packages the source tree

I think your question is how to generates several packages from a
single CMake handled project.
My answer is that this "sub-package" splitting should be handled
through the CMake INSTALL "component" feature.

However I must admit I don't know how it work.
I did some test and get
make list_install_components
to tell me I did define
Available install components are: "Development" "Runtime"
install component
but I don't know how to call

make install

properly to only install the selected component
once this is done I think I may define an [RPM] package for each
installable component.

Anyone here to explain us how should
INSTALL (xxxx ... COMPONENT ...) work?

the only references I found is:
cmake --help INSTALL which is not helpful
http://www.vtk.org/Wiki/VTK/New_Install_Framework
http://www.cmake.org/Wiki/CMake:Install_Commands

all of them tells that one may use COMPONENT
but I did not find how to invoke
make
in order to use the component framework?
