win_add_dll_directory(+AbsDir)

This predicate adds a directory to the search path for dependent DLL files. If possible, this is achieved with win_add_dll_directory/2. Otherwise, %PATH% is extended with the provided directory. AbsDir may be specified in the Prolog canonical syntax. See prolog_to_os_filename/2. Note that use_foreign_library/1 passes an absolute path to the DLL if the destination DLL can be located from the specification using absolute_file_name/3.
