No SOURCES given to target

Hi!
i have installed cocos into another machine (linux)
using Qt Creator as well, after successfully passed all installation instructions, i copied all my source and header files from my game, added the names to CMakeLists.txt but when i save it, it says:

CMake Error at CMakeLists.txt:140 (add_executable):
No SOURCES given to target

Any help?
thanks.

Show more please.

Hi!.. CMakeLists.txt had some problems, i created a new project and all is fine now. thanks.
