Makefiles are pretty strange things. There is a new wildcard target which will copy any .ogg file from "assets/" into "out/assets". On it's own, it does nothing -- it only knows how to create the output file by copying the input one. To drive this, a list of output assets must be created and depended upon by the main build target(s). I don't want to manually maintain an asset manifest in a Makefile, so I've achived this by wildcard matching anything in the "assets/" folder, then rewriting the prefix to be "out/assets/". This list is in a variable, which is now part of the dependency list for the main build target(s). All files will be installed, but only when they are out-of-date. Excellent.
