What's wrong with a rule that copies .png files from the src to the
build directory? As long as you have the .png files defined as
prerequisites of a file you're building, this will work. you'll have to
use /something/ to define them as prerequisites: either manually
maintaining a list in a makefile, or a naming convention, or copying all
the .png files in the given src directory, or running a script to
extract the information from another file and creating a file for
including in a makefile, ...
