#import: Cannot open file "soap12.h" for reading gSoap in VS 2010

I'm trying to use gSoap2.8 with VS2010 C++ project I declared a pre-build event

wsdl2h.exe -o test.h "test.wsdl"

then it says

error C1083: Cannot open type library file:<path>\stlvector.h: Error loading type library/DLL.  <path>\test.h

So I used -s to get rid of that as follows

wsdl2h.exe -s -o .\test.h "test.wsdl"

but then it say

error : #import: Cannot open file "soap12.h" for reading

How can I get rid of this?
