At the time you define the "all:" rule:

> all: $(MANUALFILES)

The variable MANUALFILES has not yet been assigned:

> MANUALFILES=$(BASEDIR)/1.txt-manual $(BASEDIR)/2.txt-manual 
> $(BASEDIR)/3.txt-manual

So at the time the "all" target is parsed MANUALFILES is empty, so the
result of the expansion of variables is just:

  all:

Since there are no prerequisites, when you run "make" or "make all"
there's nothing for make to do.

It's important to understand the way make expands variables; you can
read about it in the manual section "How make Reads a Makefile":
