It appears that you have not added these source files to your target. You should change your CMakeLists.txt file to directly add the generated files to the target. For example FTLK_WRAP_UI(foo src1 src2 src3) will create a variable named foo_FLTK_UI_SRCS that contains the list of sources to add to your target when you call ADD_LIBRARY or ADD_EXECUTABLE. For now CMake 2.2 will add the sources to your target for you as was done in CMake 2.0 and earlier. In the future this may become an error.","Warning");
