Use the same makefile for make (Linux) and nmake (Windows)

Question

I have a simple C program (one source file) which I want to compile on Linux and on Windows via make and nmake, respectively. Is there a possibility to accomplish this with

Answer 1

My solution is to use two different filenames. (since the Makefile name searching priority in different OSes will not be the same)

For Windows, I use normal "Makefile."

For Linux, I use the special "GNUmakefile" according to this article.

So that nmake (Win) will find "Makefile," and make (Linux) will find "GNUmakefile."
