static linked ncat - can't find openssl

["Dewhirst, Rob" <robdewhirst () gmail com>]

I am following the instructions at:

https://secwiki.org/w/Nmap/Ncat_Portable

Everything works fine until I try to build ncat and VS C++ says it
can't find the openssl lib and include files after I moved them to
c:\nmap\mswin32\OpenSSL

I am pretty sure I have them in the right location:

c:\nmap\mswin32\OpenSSL\include\openssl>dir ssl.h
 Volume in drive C has no label.
 Volume Serial Number is 9C14-D2A1

 Directory of c:\nmap\mswin32\OpenSSL\include\openssl
