When you use import directive to import one IDL file into another, MIDL just
puts signle #include statement in the generated header file. That's why you
can't see the imported interface. Let's suppose you have files A.IDL and
B.IDL and you want to import file B in A. Then the situation will look like
this:
// A.IDL starts here
...
import "B.IDL";
...
// Geenrated A.H starts here
...
#include "B.H";
...
So, there is no problem to use interfaces from B.IDL.
I'm not sure about importing the file in library section, but if you have
problems you can try to move the import "CP.IDL" at the begining of the
file.
