# Mark a .cpp file as depending on a .png one

# First, we mark code.o as requiring image.o. Rules will take care of inlining
# the PNG and building the inlined cpp file. Second, we add the directory
# corresponding to the one of code.cpp in the output dir as a header search
# path. Since $1 can be a list, we have to map with foreach.
