Firstly, thank you for this, it is excellent!

For Apple framework inclusion I added: FWFLAGS := -framework CoreFoundation -framework CoreGraphics -framework CoreText -framework CoreServices and appended it to # Task producing target from built files.

I had to remove $(LDPATHS) $(LDFLAGS) from the # Compile all cpp files stage as I got warnings about unused flags. Is this normal?

Did you need to remove both or may be just LDPATHS. Are they empty? They are set in the # Library search directories and flags section.

I had to remove both from the # Compile all cpp files section. I do have them set to something. But it seems those flags were only used in # Task producing target from built files.
