no.

In the meantime I found a simpler way by appending all pathes from 
KDEDIRS (+ 'share/apps/cmake/module') added to the CMAKE_MODULE_PATH  in 
FindKDE4Internal.cmake. As an alternative the path list generated by 
'kde4-config --path data'  could be added.  This makes it able to use 
cmake modules without any additional effort from *all* KDE install 
locations.

The appended patch provides this support by using KDEDIRS. any problems 
with this patch ?
