I set my minimum required version to 3.6, which should enable those policies by default (if they're truly in 3.1 as you indicated).
My CMake scripts do a lot of work to build a "tree" of properties connecting targets, so that I can recurse the targets my system generates to process things. CMake does not natively offer the ability to recurse targets created AFAIK. I suspect a lot of this logic is what is causing the slow down, but at this point I have no tooling to help me prove that. I have included the developer list, maybe the CMake developers have some insight for me as this doesn't seem to be a common user issue from what I can tell.
