I agree that a separation of CMake and the find_modules make sense. But. Then it is time to think of a way to integrate cmake with the separate source of find_modules. Algorithmically, it would look like 

PROJECT(MyApplication)
FIND_MODULES_REPOSITORY("http://ecm.kde.org")
FIND_PACKAGES(KF5 REQUIRED...)

and so forth. That would be a real breakthrough. It is related to the approach taken by Maven and others. All it takes is a built-in way for CMake to download the find_modules into a cache location and update them when needed, or on request. 

This would also make a lot of things a lot easier. For example, nobody would need to separately install ECM, and updates to our ECM packages can be delivered globally by commits to that repo. 

Cheers, 

Mirko.
