What these make messages mean while compiling sane-backends?

Question

I tried to compile the sane-backends from source but getting the following messages after running make, to configure I ran ./configure --enable-avahi BACKENDS='canon genesys test'

Okay, I got it, make says what it does, if it has nothing to do, it just says "nothing to do", thanks to all.
