In fact it does but you did not see what happened.
Your install script:

execute_process(
  COMMAND ${CMAKE_COMMAND} -E create_symlink file link
  WORKING_DIRECTORY ${CMAKE_INSTALL_PREFIX}/share/TestLink
  )

does not support DESTDIR, which is used by CPack in order to install locally
(inside build/_CPack_Packages ... )
before packaging.

You should use:
execute_process(
  COMMAND ${CMAKE_COMMAND} -E create_symlink file link
  WORKING_DIRECTORY $ENV{DESTDIR}${CMAKE_INSTALL_PREFIX}/share/TestLink
  )

and this should work in both cases (make install and CPack run).
