I have some doubt, could give us at least a couple of example
of your
install(... DESTINATION ..)

command taken from your CMakeLists.txt

CMAKE_INSTALL_PREFIX, shouldn't be there **AT ALL** unless you either

1) use something like:
    install(TARGET <targetname> DESTINATION ${CMAKE_INSTALL_PREFIX}/lib)
    which is wrong.

2) set CPACK_SET_DESTDIR
    see: --help-variable CPACK_SET_DESTDIR

If you want that then you should do:

install(TARGET <libtargetname> DESTINATION installed/other/directories/lib)

Yes I got that now.
I'm pretty sure it works.

Could you tell us which version of cmake/cpack you use?
i.e.

cmake --version
cpack --version

And then, what value do they currently have?

You're welcome.
