When we have to generate two different setup packages
from the same project (modules, libraries, data-files, etc...)
we want to have opportunity to install/update/delete them independently.
But the later installed package would overwrite the 'Uninstall.exe'.
This patch fixes the issue by customizing uninstaller name:
set (CPACK_UNINSTALL_NAME "My Custom Uninstaller Name")
before directive
include (CPack).
