I'm trying to use nmake to build the libfcg (http://www.fastcgi.com/), however I'm getting the following error:
..\include\fcgios.h(23) : fatal error C1083: Cannot open include file: 'windows.h': No such file or directory
I have the Widows SDK installed and the Windows.h file is present in this directory:
C:\Program Files\Microsoft SDKs\Windows\v7.0A\Include
How can I specify this as an include directory?
