[CMake] qt4_add_translation from build directory

[Norbert Bokor]

Hi guys,

I have a small Qt project, with two .ts files. In the CMakeLists.txt I 
have the line QT4_ADD_TRANSLATION(qmfiles ${TRANSLATIONFILES}).
It works perfectly when i run 'cmake . && make' from the source 
directory, but if I do the same from an other directory, I get an error 
from make. The problem is that the .qm files are created in the build 
directory, but make looks for them in the source directory. Is it a bug, 
or should I modify something?

Thanks in advance for the help

regards
