I tried VS2012 Native Tools, Cross Tools and Developers command prompt. And it does not recognize 'nmake'. It didn't work on VS2010 either.
On VS2008, it could not find depencies like windows.h
I want to build a static library curl for VS2012: http://quantcorner.wordpress.com/2012/04/08/using-libcurl-with-visual-c-2010/
