Should not generate wrappers for classes marked by CS_IGNORE

[vonzepp]

I have 2 simple header files:
ClassA.h:

#pragma once
#define CS_IGNORE
#define DLL_API __declspec(dllexport)
#include "UnusedClassB.h"

class DLL_API ClassA
{
private:    
    CS_IGNORE UnusedClassB m_not_for_generation;
};

UnusedClassB.h

#pragma once
class UnusedClassB
{
};

Generator setup:

            setup.Options.Headers.AddRange(new []
            {
                "ClassA.h",
            });

UnusedClassB.h is not added to header files !

Generated classA.cs:

public unsafe partial class ClassA : IDisposable
{
    [StructLayout(LayoutKind.Explicit, Size = 1)]
    internal partial struct Internal
    {
        [SuppressUnmanagedCodeSecurity]
        [DllImport("Quants.Storage.dll", CallingConvention = global::System.Runtime.InteropServices.CallingConvention.Cdecl,
            EntryPoint="??0ClassA@@QEAA@AEBV0@@Z")]
        internal static extern global::System.IntPtr cctor_1(global::System.IntPtr instance, global::System.IntPtr _0);
    }

As you can see 'm_not_for_generation' field does not generated due to CS_IGNORE (it's correct), but UnusedClassB.cs was generated! That's wrong. Generation for UnusedClassB should be ignored completely, because it is not specifyed directly and ClassA is not depend on it (in generated code).
