I would say I owe this answer as a part of my lecture :)
This is a part of a sample makefile.in (the one I currently use). Since it
is the part after the
definitions, most of it may also get inserted straight into the makefile,
given
that MACHINE_TYPE is declared by hand.
the objects are created in $(MACHINE_TYPE)/$(OUTPUT)_o/, to
allow for different
objects to be held for debug mode (objects compiled with -g are held in
machine_type/outputg_o/, because of the recursive make in the end of this
makefile, which changes the OUTPUT to OUTPUTg.
#output name, a base name to be used to creat executables and libraries.
OUTPUT=proggie

CSOURCES= $(wildcard *.c)
#identify fortran sources
F77SOURCES= $(wildcard *.f)
F90SOURCES= $(wildcard *.f90)
FSOURCES= $(F77SOURCES) $(F90SOURCES)
#create the expected object names, those that will be used to the final
#linkage
COBJS:= $(patsubst %.c,%.o,$(CSOURCES))
FOBJS:= $(patsubst %.f,%.o,$(F77SOURCES)) $(patsubst %.f90,%.o,$(F90SOURCES))
#include file, which the fortran files depend upon.
#I still need to figure out if and how to do a make depend for fortran
INCS= $(wildcard *.inc)

#the list of objects
OBJS_NODIR = $(OTHER_OBJS) $(LIBOBJS)
#the list of objects, placed at the right place
OBJS = $(patsubst %.o,$(MACHINE_TYPE)/$(OUTPUT)_o/%.o,$(OBJS_NODIR))
