How to set acrhive file directive?

Hi, all

To support archive file, wxWidgets has some directive:
wxUSE_ARCHIVE_STREAMS,
wxUSE_ZIPSTREAM,
wxUSE_TARSTREAM,
wxUSE_ZLIB,
and so on.
And under windows, all of them is default 1. (include/msvc/wx/setup.h)

Should I include setup.h file in header file? It seems not a good idea.
And how to set it under other OSs?
