Makefile is getting overridden after update on System Workbench STM32

[SS.Sagar]

Hi

I am using system workbench stm32 for my development. I am adding my own folder with few source and header file. After that i was trying to update the Makefile but make file is getting overridden.

makefile was from Release and Debug folder from workspace. Makefile under Release and Debug shows header like following.

These are auto-generated makefiles but where can i add source file path.

################################################################################
# Automatically-generated file. Do not edit!
################################################################################

I don't see where i can update new source file path.
