Dear Bert Thank you for the pointer!I read somewhere on Stackoverflow that VPATH may be used for targets as well.. can't find the link now.
Anyway, I've just tried to apply what I understood from below article, but I'm still getting the same error.
What I've changed in the Makefile:- I've added $(addprefix) to include the out/ path in the target file name - I've added out/ in the pattern rule, even if I suspect it's not necessary
- I've removed the full paths in the pandoc command $ cat Makefile VPATH = \ $CURDIR/src .PHONY: all book test all: book out/%.pdf: %.md pandoc -f markdown -o $@ $<; # Find the PDF files to be builtbook: $(addprefix out/, $(addsuffix .pdf, $(notdir $(basename $(wildcard src/*.md)))))
# Check target list test:echo "$(addprefix out/, $(addsuffix .pdf, $(notdir $(basename $(wildcard src/*.md)))))"

Dear Frederico, I just read (again) this: http://make.mad-scientist.net/papers/how-not-to-use-vpath/ you should do this too.
