[Cmake] WinMain

[Andy Cedilnik]

Hi Nick.

It has to do with another one of those weird things on Windows. When
creating a windows app, you really need function WinMain() and not
main(). For example of that one, look here:

http://public.kitware.com/cgi-bin/cvsweb.cgi/ParaView/GUI/Client/ParaView.cxx?rev=1.110;content-type=text%2Fplain;cvsroot=ParaView

This is the prototype:

int __stdcall WinMain(HINSTANCE hInstance,
                      HINSTANCE hPrevInstance,
                      LPSTR lpCmdLine, int nShowCmd)

and lpCmdLine holds string with all arguments.


Good luck.

			Andy
