Did you build with the -lole32 library?

IShell should be declared here; although as you have mentioned it
doesn't exist in the import library.  It is also not defined in the
Structures.h file.

You will need to find the defintions for IShell*.  You will need to
recreate the libole32.a import library with the IShell definitions. 
You will need to define the IShell in the Structures.h file.
