I had written Non Recursive Makefile Boilerplate (nrmb) for C, which should work in large projects with recursive directory structure. There is no need to manually add source file names in makefile, it automaically do this. One makefile compiles it all. Of course, it isn't perfect but it does the job and you can modify it for your project. Here is the link
