Simple Makefile for ADMB

Tested with gnu make under 64bit linux. Some modifications required for other configurations. Steve added contributed libraries to path.

    # to make executables with ADMB "safe" library, simply type make target
    # to make executables with ADMB "optimized" library, type make OPT=TRUE (yes, upper case) target
    # the safe version also sets the debugger flag and does no optimization
    #
    # identify some extra file name suffixes
    .SUFFIXES: .tpl .cpp .o .obj

    # tell make not to delete these intermediate targets
    .PRECIOUS: %.cpp %.o %.obj

    # make some special targets
    .PHONY: default rules

    # does this if no target is specified on command line
    default:
    	@echo No target specified.
    	@echo Usage: make target, e. g. make simple
    	@echo        specify OPT=TRUE to build optimized version

    # establish the C   compiler
    CC=g
    # and linker
    LL=$(CC)

    # set up ADMB flags and appropriate libraries
    # make the "safe" version by default
    # to make "the optimized" version, type  `make OPT=TRUE
    ifeq ($(OPT),TRUE)
