CPack Archive generator doesn't use CPACK_ARCHIVE_FILE_NAME

Given a simple CMake project like this:

cmake_minimum_required(VERSION 3.13)
project(cmake-test)

set(CPACK_GENERATOR ZIP)
set(CPACK_PACKAGE_FILE_NAME foo)
set(CPACK_ARCHIVE_FILE_NAME bar)

include(CPack)

, building the package target produces a foo.zip file, instead of bar.zip as implied by the documentation. cpack -V -G ZIP output:

CPack: Enable Verbose

I've checked this with:

• CMake 3.13.4 (Linux),
• CMake 3.16.4 (Windows).
