The point is that I want a MakeFile that creates only the .o file,
doesnt try to get binary. Next that same Makefile (and other ones)
need the .o file to make other binaries.

By the solution I wrote, cmake told the Makefile to create .o files,
but it saves them in CMakeFiles dir, I dont know where I can tell to
save in obj/ directory...
