How's libdiff2 not a "proper" lib? It's a versioned shared library. I think we 
aren't currently installing the development headers (oops), but this is 
trivial to fix.

You can build just Kompare, and I think it would be very easy to allow you to 
build just libdiff2. You don't need all of kdesdk.

Then make the plugin which depends on libdiff2 optional.

I think making sure headers are installed and allowing you to build the 
subdirectory on its own would be sufficient for that. I guess we could also move 
libdiff2 from kompare/libdiff2 to the root of kdesdk.

As I explained, for a full split, it's probably best to wait. I think kdesdk 
is likely getting split anyway for the git migration.

All the versions which we released as part of stable kdesdk versions are 
stable versions.
