kdelibs is feature frozen.
I'd consider this a (buildsystem) feature.

This work is still for kdelibs 4, right ?

Is there a pressing need to get this into kdelibs ? If not, just use your own 
copy, but don't install it.

For the review: please remove the if(QTOAITH_INCLUDE_DIR AND QTOAUTH_LIBRARY), 
such micro-optimizations can only create problems.
find_package_handle_standard_args() etc. work better without it. It e.g. takes 
care itself of not printing the same message again on every run, it only 
prints a message if something has changed.
