This lets you call a makefile in another folder without having to incorporate it into your own lock, stock, and barrel.

make supports recursion directly, and will tell you how deep into recursion it is.
I cannot quite understand how to use the above code

My directory structure is as below. The user uses Makefile. The makefile calls
the makefile for the specific program.

Code:
.
├── Makefile
└── mk
    ├── fdtc.mk
    ├── raypk.mk
    └── zslice.mk

Here is the code for Makefile

Code:
default: help

help : help-nfdtc help-nraypk help-xraypk help-xzslice 

help-nfdtc : 
    $(MAKE) -f fdtc.mk help

help-nraypk : 
    $(MAKE) -f raypk.mk help

help-xraypk : 
    $(MAKE) -f raypk.mk help

help-xzslice : 
    $(MAKE) -f zslice.mk help

list : list-nfdtc list-nraypk list-xraypk list-xzslice

list-nfdtc :
    $(MAKE) -f fdtc.mk list
    
list-nraypk :
    $(MAKE) -f raypk.mk list

list-xraypk :
    $(MAKE) -f raypk.mk list
    
list-xzslice :
    $(MAKE) -f zslice.mk list
    
#---------------------------------------------------------------------------------------------------

nfdtc :
    $(MAKE) -f fdtc.mk nfdtc

nraypk :
    $(MAKE) -f raypk.mk nraypk

xraypk :
    $(MAKE) -f raypk.mk xraypk

xzslice :
    $(MAKE) -f zslice.mk xzslice

#---------------------------------------------------------------------------------------------------

clean : clean-fdtc clean-raypk clean-zslice

clean-fdtc :
    make -f fdtc.mk clean

clean-raypk :
    make -f raypk.mk clean

clean-zslice :
    make -f zslice.mk clean

xmkmf

XMKMF(1)						      General Commands Manual							  XMKMF(1)

NAME

       xmkmf - create a Makefile from an Imakefile

SYNOPSIS

       xmkmf [ -a ] [ topdir [ curdir ] ]

DESCRIPTION

       The xmkmf command is the normal way to create a Makefile from an Imakefile shipped with third-party software.

       When  invoked with no arguments in a directory containing an Imakefile, the imake program is run with arguments appropriate for your system
       (configured into xmkmf when X was built) and generates a Makefile.

       When invoked with the -a option, xmkmf builds the Makefile in the current directory, and then automatically executes ``make Makefiles'' (in
       case  there are subdirectories), ``make includes'', and ``make depend'' for you.  This is the normal way to configure software that is out-
       side the X Consortium build tree.

       If working inside the X Consortium build tree (unlikely unless you are an X developer, and even then this option is never really used), the
       topdir  argument  should be specified as the relative pathname from the current directory to the top of the build tree.	Optionally, curdir
       may be specified as a relative pathname from the top of the build tree to the current directory.  It is necessary to supply curdir  if  the
       current	directory  has	subdirectories, or the Makefile will not be able to build the subdirectories.  If a topdir is given, xmkmf assumes
       nothing is installed on your system and looks for files in the build tree instead of using the installed versions.
