The contents of installed aren't important, just that I can collect them in the desired arrangement and then put them into a package, created by CPack, so they can be installed where the user chooses.  I'd also like a default location for installers (not for zip files or tarballs, of course).

That's pretty clear, however giving a minimal set of example files
including CMakeLists.txt
would ease understanding.

I have several question:

Q1) Do all your install(... DESTINATION relpath/to/install) have
relative path destination or not?
Q2) What is the exact set of CPack generator you need?
      all the archive generators (ZIP, TGZ, TBZ2, etc...) may be
handled the same way
     but "installers" (DEB, RPM,NSIS, ...) do have specific config var.
Q3) Do you use COMPONENT packaging or not?

Could you give us a complete (minimal) example of what you get and
what you would expect?
With the "archive" generator like TGZ you may play with:

CPACK_INCLUDE_TOPLEVEL_DIRECTORY
CPACK_COMPONENT_INCLUDE_TOPLEVEL_DIRECTORY
in order to put/remove the toplevel directory in the archive.

e.g.
cpack -G TGZ -D CPACK_INCLUDE_TOPLEVEL_DIRECTORY=0

builtin doc:
cpack --help-variable CPACK_INCLUDE_TOPLEVEL_DIRECTORY
cpack --help-variable CPACK_COMPONENT_INCLUDE_TOPLEVEL_DIRECTORY

cpack --help-variable CPACK_PACKAGE_INSTALL_DIRECTORY
cpack --help-variable CPACK_PACKAGING_INSTALL_PREFIX
cpack --help-variable CPACK_NSIS_INSTALL_ROOT

If you have more question please give us a
non-working complete but minimal example to play with.
