Spit Balling #163
Description
It looks CMake has overhauled the find_package command.
In particular it looks like you can have find_package defer to FetchContent (see here). Similarly you can have find_package defer to an actual package manager
(see here).
My thought is we could potentially rely on this functionality instead of our PackageManager class. The idea would be to punt to say Spack, but still support our API. Will need to look into this more.
