title: ZXingWidget: Counted.h file not found
body: <p>I am building an iPhone app using ZXingWidget.  I followed the README instructions and got everything setup in my project and it compiled with no problem.  I then imported QRCodeReader.h in my view controller header file and started to get the following error on compilation of FormatReader.h:</p>
  
  <p><em>Lexical or Preprocessor issue 'zxing/common/Counted.h' file not found.</em></p>
  
  <p>I realized I had forgotten to rename my view controller implementation file from .m to .mm so I did that.  However, I am still getting the error.</p>
  
  <p>Any suggestions?</p>
  
  <p>EDIT: Here is the directory layout for my "QR Scan" project.  You will see that "cpp" is under the "Projects" folder and that "QR Scan.xcodeproj" is in the "QR Scan" folder.  I have "../cpp/core/src" in my headers for my QR Scan Xcode project.</p>
