Targets
In a dependency line, specify one or more targets, using any valid filename, directory name, or pseudotarget. Separate multiple targets with one or more spaces or tabs. Targets are not case sensitive. Paths are permitted with filenames. A target cannot exceed 256 characters. If the target preceding the colon is a single character, use a separating space; otherwise, NMAKE interprets the letter-colon combination as a drive specifier.
