That's a GNU autotools setup, not a pure Makefile setup. A simple Makefile setup is much much easier. A current C project I'm working on has around 150 lines worth of Makefile stuff, and that includes both compiling source, running flex over lexer files, an option for creating a .tar.gz of the current source, and also an option to run tests on the compiled object files. It's also dead simple to maintain (The only time it requires a direct update is when adding test cases, and that's because you have to specify which source .c files to test). Now to be fair, I am sacrificing some options here. The biggest is that autotools runs tests on the installation environment and tests the available functions and standards compliance, which in theory allows compiling the source on any system with has autotools for it, which is why it's so huge. You can't do that with standard Makefiles. I just stick close to the standard and avoid any non-standard extensions that I don't need.
