Scope package options to avoid changing the local scope (#235) * Fix #222 * Fix #222 * move policy change and local options to cpm_add_subdirectory * change default policy as well see https://gitlab.kitware.com/cmake/cmake/-/issues/20312 * add test * update check to not use the NOT operator (interestingly it works as expected locally) * simplify test by not using options * check options in tests Co-authored-by: Lars Melchior <TheLartians@users.noreply.github.com> 2021-03-25 22:59:34 +08:00			`cmake_minimum_required(VERSION 3.0 FATAL_ERROR)`
