This feels more like a "patch" operation to me, so wouldn't putting this in 
%prep (rather than %build) somewhere make more sense?

Thinking a bit more... would it be too evil to macro'ize this somehow, say 
hook into %cmake_kde for example, to operate automatically on all 
metadata.desktop files found in $RPM_BUILD_DIR ?
