Summary:                    Support install of external projects, with
component-like selection
Description: 
While considering ways to make a useful 'install' target for a superbuild-like
project (Slicer), JC and I decided it would be nice if CMake had a mechanism
similar to CPACK_INSTALL_CMAKE_PROJECTS.

We propose CMAKE_INSTALL_CMAKE_PROJECTS, a list of sets of three values: build
directory, project name, install prefix. If set, when the install script is
generated, it would include the install script of each such project (i.e.
"include(<build_dir>/cmake_install.cmake)") after first modifying the install
prefix as specified. (An empty or relative prefix would be relative to the
parent install prefix.) A system for selecting project(s) to install, similar to
selecting component(s) to install, would be provided.

We could then modify external project support (e.g. this would probably happen
first in Artichoke) to have a command like:

  ExternalProject_Install(<name> [DESTINATION <path>] [CPACK_COMPONENT
<component>])

...which would set both CMAKE_INSTALL_CMAKE_PROJECTS and, if a CPACK_COMPONENT
is specified, CPACK_INSTALL_CMAKE_PROJECTS.
