The place for this to go would be in both cmGlobalXCodeGenerator.cxx and 
cmXCodeObject.cxx.


You should change this method in cmGlobalXCodeGenerator.cxx
cmXCodeObject*
cmXCodeObject*
cmGlobalXCodeGenerator::CreateXCodeFileReference(cmSourceFile* sf,
                                                  cmTarget& cmtarget)

...

  if(!fileRef)
     {
     fileRef = this->CreateObject(cmXCodeObject::PBXFileReference);
     std::string comment = fname;
     //comment += " in ";
     //std::string gname = group->GetObject("name")->GetString();
     //comment += gname.substr(1, gname.size()-2);
     fileRef->SetComment(fname.c_str());
     this->FileRefs[fname] = fileRef;
     fileRef->CreateFileIdHash(fname);  // **** Add this line
     }


Then add the method CreateFileIdHash to cmXCodeObject.(h/cxx).  It 
should set the Id to the string that contains the hash.

I think that should do it.
