Subject: cpack: Disable CMake Cygwin legacy warning while packaging

In cpack we load the platform information modules to give the
configuration scripts access to the host system information.
CYGWIN.cmake warns unless we explicitly tell it not to warn
since there is no chance for a cmake_minimum_required(VERSION)
to be called.
