title: Customizing the source and target locations in a makefile
body: <p>I am a newbie to Creo toolkit. For trial purpose, I need to edit the location of the source and target folders in the default make-file available. A part of the make-file is given below for reference.</p>
  
  <pre><code># File Name
  MAKEFILENAME = make_install
  
  # Machine Type
  PRO_MACHINE_TYPE = x86e_win64
  
  # Executable names
  EXE = pt_inst_test.exe
  EXE_DLL = pt_inst_test.dll
  
  # Pro/Toolkit Source &amp; Machine Loadpoint  (EXTERNAL USE - DEFAULT)
  PROTOOL_SRC = $(PROE_INSTALL_PATH)\protoolkit
  PROTOOL_SYS = $(PROTOOL_SRC)/$(PRO_MACHINE_TYPE)
  
  # Pro/Toolkit Source &amp; Machine Loadpoint  (PTC INTERNAL USE)
  #PROTOOL_SRC = $(PTCSRC)/protoolkit
  #PROTOOL_SYS = $(PTCSYS)
  
  # Include File Paths
  INCS = -I. -I$(PROTOOL_SRC)/protk_appls/includes -I$(PROTOOL_SRC)/includes
  </code></pre>
  
  <p>In the above given code, I need to replace the source (PROE_INSTALL _PATH) with the required folder location (For ex: C:\Users\sagarp\Desktop\trial) without editing the environment variable. Is it possible? If so, please help me with the basics of creating a make-file on my own.</p>
