This behavior is "normal".
You should'nt refer to ${DESTDIR} in your CMakeLists.txt
DESTDIR is used at "make install" time and not at CMake run time.

In your case putting ${DESTDIR} should evaluate to empty string
giving in both cases:
INSTALL(PROGRAMS spm-check  DESTINATION /etc/rc.d/init.d)
which is an absolute PATH case which does not work (either RPM or DEB)
when CPACK_SET_DESTDIR is OFF (default case).

I've submitted a bug report:
http://public.kitware.com/Bug/view.php?id=6673

When using relative path:
INSTALL(PROGRAMS spm DESTINATION sbin)

the path is prefixed with CMAKE_INSTALL_PREFIX you can
choose at CMake run time.
If you didn't chose one the default value is "/usr/local"
thus the result for RPM case.

As I told previously DEB generator seems [consistently] buggy
regarding absolute path handling in both cases.

So your results are consistents :-).
