7.5.2 Definitions Search Path

As an alternative to the normal search path set with –I, you can specify a search directory for template definition files with the option –ptidirectory. Multiple -pti flags define multiple search directories—that is, a search path. If you use -ptidirectory, the compiler looks for template definition files on this path and ignores the –I flag. Since the –ptidirectory flag complicates the search rules for source files, use the –I option instead of the –ptidirectory option.
