There's no reason to write Makefiles by hand now that Emacs can do it
for you.  M-x ede-new to create a new project (choose a "Make" project),
then M-x customize-project.  For simple projects it is tons easier than
creating a Makefile by hand, especially considering all of the targets
that EDE gives you for free.

Plus, creating a project teaches Emacs how your project is organized.
Not only does this allow you to easily run the build from inside Emacs,
but it allows you to query and search your files by project as well.

I hit C-x <space> in the source window.  There probably is a way to use
the mouse.  To be honest, I don't use the debugger much.  I probably
should.
