Makefile: Multiple targets, one dependency

I have a script that generates 2 code files (For example, src1.c, src2.c) according to another code file (say origin.h).
I use a makefile to build them.
Now, I want the script to be executed when src1.c OR src2.c is older that origin.h.

What is the best way to do that?

Thanks.

Make src1.c and src2.c jointly dependent on origin.h:

src1.c src2.c : origin.h
        build-sources
