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

CREATE_MAKEFILES()														CREATE_MAKEFILES()

NAME
create_makefiles - Recreates all Makefiles beneath a directory SYNOPSIS
create_makefiles [dir] DESCRIPTION
create_makefiles recreates all Makefiles in dir and its (recursed) subdirectories from the corresponding Makefile.am templates. This script must be run from the toplevel directory (the one containing configure). This script saves time compared to re-running configure completely. If the source directory is different from the build directory (see the environment variables below), it will be assumed that each Makefile.am and Makefile.in belongs beneath the source directory and that each Makefile belongs beneath the build directory. This utility is part of the KDE Software Development Kit. ENVIRONMENT
One of the following variables (but not both) should be set if the source directory is different from the build directory. If the build directory is simply a subdirectory of the source directory, the simpler variable OBJ_SUBDIR should be used. OBJ_SUBJDIR Indicates that the build directory is in the given subdirectory of the source directory. For instance, if the source directory is kdesdk and the build directory is kdesdk/obj-i386-linux, then OBJ_SUBDIR should be set to obj-i386-linux. OBJ_REPLACEMENT A sed expression that is used to transform the source directory into the build directory. For instance, if the source directory is kdesdk/obj-i386-linux, then OBJ_REPLACEMENT should be set to s#kdesdk#kdesdk-obj#. SEE ALSO
