# Windows installer written by Inno Setup, through CPack's own InnoSetup generator.

# Included from the WIN32 branch of the top-level CMakeLists.txt when
# COCKATRICE_WIN_INSTALLER is InnoSetup. It sits next to the NSIS template rather than
# replacing it so both installers can be built from the same 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.
