Specifying the Object Directory

Several project properties are modeled by Ada-style attributes; you define the property by supplying the equivalent of an Ada attribute definition clause in the project file. A project's object directory is such a property; the corresponding attribute is Object_Dir, and its value is a string expression. A directory may be specified either as absolute or as relative; in the latter case, it is relative to the project file directory. Thus the compiler's output is directed to /common/debug (for the Debug project) and to /common/release (for the Release project). If Object_Dir is not specified, then the default is the project file directory.
