follow these instructions to get this
thing compiled in no time. (works with visual studio 6, 
.net you're on your own ;)

put .lib files in \Microsoft Visual Studio\VC98\Lib\

put everything else (.h, .nh, .inc) in 
\Microsoft Visual Studio\VC98\Include\

i dont exactly know if you need all of them, but
to be on the safe side why not.
