Ok, this previous commit was wrong.
Please move these three files back, and remove that line again.

A library must never install the Find-module for itself.

This defeats the purpose. This is like putting the remote control right next 
to the TV, or the treasure map right into the treasure chest. You don't know 
where the plan is, but once you found the plan, you already found what you are 
interested in and don't need the plan anymore.

Additionally, in general ${CMAKE_INSTALL_PREFIX} does not have to exist yet at 
cmake time, so it only happens to work if you "accidentially" use the same 
install prefix as you used for kdewin32.

So, in the 4.x branch, please move these files back to kdelibs.
For the frameworks branch, they will go into extra-cmake-modules, so they will 
be available to you (after a find_package(extra-cmake-modules).

Ideally the kdewin32 library should install a cmake config file for itself. 
But let's wait with this until cmake 2.8.8 has been released.
