Best solution is to provide a Config-file from libkactivities I think :)

A project like extra-cmake-modules installing Find-modules always has
the problem of needing to keep source-compatibility for a reasonable
timeframe, so that other projects can rely on it when writing their
CMake-code. This means the find-modules need to be written carefully and
tested thoroughly.

For libkactivities this would however probably be better than shipping a
Find-Module in each project using the library since I think you expect
many such projects - so synching the individual files would be a major
pita.

If you stick to a Find-module you should ultimately target inclusion
into cmake though I think. I believe the CMake wiki has a page
describing the process and ones obligations when maintaining a
find-module.

Note: All this is from memory, so if you want 100% clarification ask
kde-buildsystem or Alexander directly :)
