rosmake cob_canopen_motor does not create a executable file ( "bin" folder still empty) [closed]

edit

I wanted to run the CanDriveHarmonica.cpp Node from the cob_canopen_motor package, but rosmake does not create the executable file Below you can see the output, there is no error, but still the binary is not built:

I already tried different things inside the CMakeList.txt and at the moment I have there only this line:

rosbuild_add_executable(CanDriveHarmonica common/src/CanDriveHarmonica.cpp)
