+ 4. Finally, you need to tell your project where to find the ZXingWidget headers. Open your
"Project Settings" and go to the "Build" tab. Look for "Header Search Paths" and double-click
it. Add the relative path from your project's directory to the
- "zxing/iphone/ZXingWidget/Classes" directory. Make sure you click the checkbox "relative path" !
+ "zxing/iphone/ZXingWidget/Classes" directory. Make sure you click the checkbox "recursive path" !
- 5. You're ready to go. Just #import <ZXingWidgetController.h> from anywhere and it should work !

+ 7. #import <QRCodeReader.h> for example because you will need to inject a barcode reader into ZXingWidgetController.

+ 8. MAKE SURE the file in which you are using the code deader is a .mm because you are now silently including some c++ code. If you don't do so then
+ the compiler will cry as if it does not find some files !

+Know issues for above steps to include:
+======================================
+ - It can happen that when trying to build your own project with ZXoingWidgetController you get linker errors like
+ "undefined reference to". If this error looks like a c++ undefined reference, then renaming main.m into main.mm (Objectice-C++ source suffix)
+ may fix the problem
+
+ - If you have building error like " ... : No such file or directory", then it is a classical error, it means that the path to includes is not well
+ specified. The best way to fix this is to look at the Build Command that failed. To do that, click on the lower right corner of your XCode project,
+ you should see the build command that failed. Click on it and expand it by cliking on the "more" symbols that just appeared. This will make appear
+ the exact command line instruction that is ran and fails. You can then make sure that the Header search path you specified is there, and you can also
+ copy/paste this line into your terminal and try to see if you can reproduce/fix the error by adding the right path to the compiler. Once is is fixed,
+ you should have an idea of what's the problem and accordingly modify your Header Search Path.
