Building curl library with GSS enabled in windows

[Vidhya Sekar]

Help needed..
I am trying to build the curl library GSS enabled in windows.
I copied the GSS related files.
I am running the below command
nmake /f makefile.vc mode=static MACHINE=x64 DEBUG=no WITH_DEVEL=../deps
WITH_SSL=static SSL_PATH=../openssl ENABLE_SSPI=yes

where I have placed all the GSS related stuffs in deps folder.
Is there any special flag I need to pass to make my libcurl GSS enabled.

Thanks in advance
