[[Help] Urgent: Write makefile

[[Help] Urgent: makefile writing-general Linux technology-Linux programming and kernel information. The following is a detailed description. For compiling makefile
I still have to deal with it in a simple way, but this job has a little more interface functions, so I really don't know how to write it. Thank you for your help!
The file structure is as follows:
Gui. c
Include/assert. h
Include/Counter T. h
Include/mem. h
Include/list. h
Include/document. h
Src/assert. c
Src/platform T. c
Src/mem. c
Src/list. c
Src/document. c

The header files in src/cmdt. c include: include "assert. h" "cmdt. h"
Src/mem. c contains the following header files: include "assert. h" "partition T. h" "mem. h"
Src/list. c contains the following header files: include "assert. h" "mem. h" "list. h"
The src/document. h header files include "Mem. h" "document. h"

Gui. c contains the following header files: include "List. h" "document. h"

So I have to ask for help!
Thank you.
