How to treat a Makefile with another name in vim?

Question

I am working in a library that has its own Makefile, so I am using my own Makefile called my_makefile and use make -f my_makefile

My problem is how to tell Vim that my_makefile is an actual Makefile and use color scheme that it use for a Makefile.

It is hard to read it now.
