Ok then it explains the difference.
File must installed at there absolute location but not package by CPack
which cannot handle aboslute location without using CPACK_SET_DESTDIR.

Another option would be to use fakeroot
see http://www.cmake.org/pipermail/cmake/2009-August/031328.html

you may simply try (without setting DESTDIR)

"fakeroot make package"

I understand for /etc files.
Then you have two options:

1) use CPACK_SET_DESTDIR

2) Install those file with install time scripts

   like postinstall script for DEB
   http://www.cmake.org/Wiki/CMake:CPackPackageGenerators#DEB_.28UNIX_only.29

   or CPACK_RPM_<POST/PRE>_<UN>INSTALL_SCRIPT_FILE
   for RPM.

   this is not possible with TGZ and ZIP.
