The validity of the answer will depend on which CMake version you use and
which set of platform you want to support.
Symlinks are not that portable
a) Creation may not be [currently] done portably but if you are targeting Unix
you can use cmake -E create_symlink to create one.
b) Depending on the CPack generator you use and CMake/CPack version
symlinks may be embedded in the package or not.
i.e. CPack pre 2.8.7 cannot create ZIP archive which contains symlinks
CPack 2.8.8 can do that now.
Then you can use an install(SCRIPT ...
or install(CODE ...) to do that at install time.
Another option if you are using RPM is to use package
specific post install script.
cpack --help-variable CPACK_RPM_POST_INSTALL_SCRIPT_FILE
this last solution will off course only work for CPack RPM.

You can use absolute destination path, they should be handled just fine
by CPack DEB and RPM, I don't know for other.
If your software should be installed on Windows this is won't work
with archive generator (ZIP, TGZ, etc...) and/or NSIS.
May be you can do something like:
if(UNIX AND NOT APPLE)
set(CONFDEST "/etc/${CMAKE_PROJECT_NAME}")
else()
set(CONFDEST "etc")
endif()
install(FILES yourconffile DESTINATION ${CONFDEST})
