XCode: Incbin stops emitting files

I have set up my IceTea tool to also build through XCode. This is merely an excercise to find my way around in the IDE itself by using code that I already wrote. On pure command line, everything works exactly as expected. But with XCode, incbin no longer emits files. I even copied the compiled binary and compared them, and saw that they were pretty different.

Here is an extract of what XCode does:

Any idea why incbin may have stopped emitting files? It reads my input as expected, but thats it. There is no emitting being done. Maybe it is using a flag that I've overseen that might be causing issues.
