Making LilyPond quickly

[Charles Winston]

Hi developers,

So far for my chords project, I’ve only been editing Scheme files, so I haven’t 
needed to build lilypond at all to test. Now I’m working on C++ files, so I 
need to compile in order to test my changes. It’s frustrating that compiling 
takes such a long time. I’m just using the “make” command, so I’m making all. I 
feel like there must be a way to compile only the specific things I changed. 
How would I do that?

Charles
