Error with BrepAlgoApi

I built a sample project with Visual C++ 6.0.
And I got this message.
"fatal error C1083: Cannot open include file: 'BRepAlgoAPI.hxx': No such file or directory"

So I tried to find the header file but it doesn't exist...
How can I handle this problem ??
Somebody help me plz~~
