From a command prompt, just "cd" into your project directory, and type "make". It's really as simple as that
Here's the deal:
1. A "makefile" is a text file that consists of a bunch of "rules" for building a program (compile, link and any other activities that need to be done). It's kind of like a shell script - except it's "declarative" (gives the rules for what needs to be done) instead of "procedural" (it doesn't spell things out step-by-step, like a programming language might).
2. When you type "make", it runs the "make" program.
The "make" program looks for a file called "Makefile" in your current directory.
If it finds it, it reads it, parses the "rules" ... and builds your program.
3. So again - if all you want to do is compile some code that already has a makefile: just start a command prompt, go to your project directory, and type "make".
