    @usage: RESOURCE_FILES([PREFIX {prefix}] [STRIP prefix_to_strip] {path})

    This macro expands into
    RESOURCE(DONT_PARSE {path} resfs/file/{prefix}{path}
        - resfs/src/resfs/file/{prefix}{remove_prefix(path, prefix_to_strip)}={rootrel_arc_src(path)}
    )

    resfs/src/{key} stores a source root (or build root) relative path of the
    source of the value of the {key} resource.

    resfs/file/{key} stores any value whose source was a file on a filesystem.
    resfs/src/resfs/file/{key} must store its path.

    DONT_PARSE disables parsing for source code files (determined by extension)
               Please don't abuse: use separate DONT_PARSE macro call only for files subject to parsing

    This form is for use from other plugins:
    RESOURCE_FILES([DEST {dest}] {path}) expands into RESOURCE({path} resfs/file/{dest})
