Automake Source Directories

[HexJunkie]

So, I'm just starting to use Automake, and in the guide that I read, this format was used:

bin_PROGRAMS=prog
prog_SOURCES=src/main.cpp src/other.cpp src/even_more.cpp

But, it mentioned that there is a way to just specify that all sources in a certain directory should be used, so that I could jus say that all .cpp files in a certain directory should be included. I'm just having trouble finding out how to do that. Can anyone help me out?

Thanks!
