Programming :: Making A Project Distribution Folder?

I'm trying to make my first c project (a simple tic tac toe console game), and I am wondering how to make a final product (copy all source code files to a distribution folder upon compilation). Should I use a bash script or should I use a makefile to make the distribution folder? I'm not terrible familiar with either; I have a basic makefile to make an executable, and that's about all I know of make.

And if I do use a bash script, how do I copy over source code files? I tried cp ./*.c and cp ./*.h, but I think the script read it literally as moving a file named ./*.c (and ./*.h), and couldn't find it.

My makefile is pretty much this:

Code:
objectFiles = main.o io.o board.o game.o
ttt : $(objectFiles)
cc -o ttt $(objectFiles)
