Java How to define dynamic Target/Prerequisite in Makefile?

I am writing a Makefile for Cobol on Linux.My sample Makefile looks like below.
I do not want to Hardcode Program names in Makefile.Is there any way we can mention directories in Target and Prerequisites instead of File names sothat Makefile Pickup all the files in mentioned path as below.
================================
Code:
#Path Variables
targetpath=/home/usr/user1/target
sourcepath=/home/usr/user1/source
#Target &Dependencies
all:$(targetpath)/$(sourcename).int
#Implicit Rule for compilation
$(targetpath)/%.int:$(sourcepath)/%.cbl
        cob $<  -C int=$@

================================
currently I am using following command which I can trigger thru Shell script.
-bash-3.2$ make sourcename=A
-bash-3.2$ make sourcename=B
-bash-3.2$ make sourcename=C
-bash-3.2$ make sourcename=D
looking forward for inputs on this.
Note .cbl is a extension for cobol code and .int is its exectable

NAME
pptemplate - script to generate Makefile.PL and PP file skeleton SYNOPSIS
# generate Makefile.PL and mymodule.pd in CWD pptemplate PDL::MyModule; DESCRIPTION
The pptemplate script is the easiest way to start a new module for PDL that contains PP code (see also PDL::PP). The usage is simply pptemplate modulename; As a result pptemplate will generate a perl Makefile for the new module (Makefile.PL) that contains the minimal structure to generate a module from PP code and also a skeleton file for your new module. The file will be called mymod.pd if you called "pptemplate" as pptemplate PDL::CleverAlgs::Mymod; I suppose you can work out the naming rule ";)". If not resort to experimentation or the source code. "pptemplate" will refuse to overwrite existing files of the same name to avoid accidents. Move them out of the way if you really want to scrap them. Options Currently there is only the "-i" option which switches "pptemplate" into the so called internal mode. It should only be used when you are starting a new module within the main PDL tree that is supposed to be part of the PDL distribution and the normal PDL build process, e.g. cd PDL/IO; mkdir Mpthree; cd Mpthree; pptemplate -i PDL::IO::Mpthree; BUGS
Maybe ";)". Feedback and bug reports are welcome. COPYRIGHT
