Review request for kdelibs.


Changes
-------

Restore the last line of CMakeList.txt file which somehow disappeared. 


Summary
-------

This patch makes the jpeg thumbnailer honor jpeg rotation infos stored in exif metadata. 
The method is quite simple, although I don't like ifdefs, this time they seem to me to be necessary.
It's my first nontrivial CMake modification; please check that I did not do something stupid there.
Also, the orientationMatrix method could be ifdeffed if you feel it is necessary; I just didn't want to add another ifdef.

I am not sure if this is a good solution performance-wise; please comment on that if you have better ideas.


Diffs (updated)

Testing
-------

Works good with a *clean* .thumbnails directory. Cached thumbnails are indeed a problem; not sure how to solve this issue yet.
