WMSDK idl files not found when linking

[aaa]

I'm trying to develop a COM object using DirectShow to support a Web cam to
use in Internet Explorer. It is my first time trying to do something like
this, and I have only been working with COM for a few months.
Linking the .NET idl files seem to be no problem:

However, when trying the WMSDK idl files it fails, even though wmsbuffer.idl
actually is in the C:\WMSDK\WMFSDK95\include folder which was used by
wmsdkidl.idl. Any ideas what I could be doing wrong or what I have left out?

Processing C:\WMSDK\WMFSDK95\include\wmsdkidl.idl
wmsdkidl.idl
midl : command line error MIDL1001 : cannot open input file wmsbuffer.idl
LINK : fatal error LNK1240: failed to compile IDL content

[shocron]

Your MIDL compiler is missing the WMFSDK95\include path

in project properties
linker -> embeded IDL

set the first line - "MIDL commands" to include the path

Add:
/I "c:\.....your sdk path ...\WMFSDK95\include"

Build the project
