I tried compiling your netwm-xcb changes (merged onto kdelibs-4.9), but it 
fails to find xcb_util.h (and the associated pkgconfig module).

(The all-in-one PKG_CHECK_MODULES makes diagnosing this a bit difficult btw.
Removing QUIET helps, though:
 package 'xcb-util' not found
 package 'xcb-ewmh' not found
)

Quick fix: comment out everything else ;)

Longer term fix: ask kde-buildsystem for the proper way to do this. Probably 
something related to the user of FindXCB.cmake asking for the modules that it 
needs. There's obviously support for that in cmake, but I don't know the exact 
details. Something with FIND_PACKAGE(XCB COMPONENTS ....). See 
FindSoprano.cmake for an example. The list could get quite long, but most code 
won't need all modules, right?

CC'ing kde-buildsystem for help.
Just in case the example I found is outdated :)
