The fact that xext is a pretty common library these days doesn't mean that
amarok doesn't have to check for it. However you're lucky, all you need to
do is check (in this particular case) for the X11_Xshape_INCLUDE_PATH as
find_package(X11) is already done when finding Qt4. But checking the
include path is not empty is really something that amarok needs to do if it
wants to use the header, especially since X11 comes in separated split
packages these days (and my kdelibs-dev, qt4-dev etc. don't even depend on
any X11-dev packages, because they don't expose X11 API themselves).
