Hi, can someone please help here... the make command fails with the below:

> make

make[1]: *** [CMakeFiles/Makefile2:541: kdecoration/CMakeFiles/lightlydecoration.dir/all] Error 2
make: *** [Makefile:149: all] Error 2

I tried even using the previous version still it fails when it comes to the make command.
