title: Failed to access the MailCore Classes in any other classes
body: <p>I have added the MailCore.xcodeproj in my application, and set the Header Search Path, Library Search Path and Framework Search Path like as it is set in Remail application. But when I am accessing the classes of the MailCore (like CTCoreAccount, CTCoreFolder, etc)  after import in any other class and creating an object like this:</p>
  
  <pre><code>#import "CTCoreAccount.h"
  CTCoreAccount* account = [[CTCoreAccount alloc] init];
  </code></pre>
  
  <p>I will get the following error: </p>
  
  <blockquote>
    <p>Undefined symbols for architecture i386:<br>
    "_OBJC_CLASS_$_CTCoreAccount", referenced from:
          objc-class-ref in ImapSync.o ld: symbol(s) not found for architecture i386 collect2: ld returned 1 exit status</p>
  </blockquote>
  
  <p>How can I resolve this error? </p>
