Complier cannot find .h files (code blocks) : Hey all I am trying to include a few libraries in code blocks, however when I add the path of the .h files to the search directory, it only seems to identify the ones in the main file and I think that is due to the fact that in the main file they are included as such (for example) #include "qtcpsocket.h", whereas in the .h file they are included as (for example) #include <QtNetwork/qabstractsocket.h>. 

Apart from the fact that one includes the folder in which it is located, what is the major different? Why it may not work? and what do it need to do to change it?
one more thing i'm sure the file are in the folder.
Here are a few code snippets if this helps
