Here's one way that VPATH can be used, with your original directory
structure. The example is a bit convoluted. A recursive Make
invocation is done to make the working directory be the 'out'
directory. The VPATH allows the sources to be found in the 'src'
directory:
export ROOT ?= $(shell pwd)
VPATH = $(ROOT)/src
MD = $(wildcard $(ROOT)/src/*.md)
PDF = $(addsuffix .pdf, $(notdir $(basename $(MD))))
%.pdf: %.md
echo pandoc -f markdown -o $@ $<; \
touch $@;
all:
$(MAKE) -C $(ROOT)/out -f $(ROOT)/$(lastword $(MAKEFILE_LIST)) book
book: $(PDF)

Answering "How do we solve this problem?" should not create more problems.
