# next to this file rather than deleted so both installers can still be built from one tree
# and compared on a real upgrade.
#
# The generator writes [Files], [Dirs], [Icons], [Run] and [Registry] from the install()
# rules the project already declares, so nothing here repeats them. What is added is only
# what the generator has no opinion about: upgrade identity, closure behaviour for a
# running application, the stale-runtime [InstallDelete], and the migration off the NSIS
# installation (both script fragments below).

# The generator itself arrived in 3.27; cmake_minimum_required() here would reset the
# policies the top level already selected, so it is refused at the include site instead.
