[Digikam-devel] Fix for default build of digikam-sc

[Andrew Goodbody]

Hi Gilles,

I just pushed a fix for CMakeLists.txt from digikam-sc as it was broken 
for the default build since your commit from 23rd March. 
DIGIKAMSC_USE_PRIVATE_KDEGRAPHICS is now always defined since it has a 
default so the test for NOT DEFINED was never going to work AFAICT.

I also fixed some typos and grammar nearby. I hope that this is all OK. 
If not please let me know.

I only found this bug because the cmake run failed so there may well now 
be problems if anyone needs to use DIGIKAMSC_USE_PRIVATE_KDEGRAPHICS=on. 
The find packages for the private libkdcraw and libksane seemed to 
return errors.
