Parsing 'include' statements in Makefiles

[adi-g15]

Some makefiles may include include statements, this commit includes support for it.

I originally searched for makefile parsers to find a way to visualise makefile of some OS projects.

For eg. Redox OS's makefile starts with these:

# Configuration and variables
include mk/config.mk

# Dependencies
include mk/depends.mk

all: build/harddrive.bin

coreboot: build/coreboot.elf

…

Which the script caught as UNHANDLED, this is my edit I made to support it.

It works well for redox, and atleast doesn't break existing usage :)

Very cool, thanks for the contribution! I am using makefile-parser more or less exclusively to have self-documenting makefiles, what are you doing with the parsing results?

Thanks, i actually just wanted to visualise Makefile of starter OSs, a temporary quick look at what components it builds etc, nothing after that, so just searched Makefile parser, found yours, would have used graphviz to get a tree/graph kind of, though not doing that, your parser is enough for me :D

As for the pr, the include lines were showing as Unhandled, that was one thing I thought can 'fix', so tried it 😅
