qt windows include boost thread header failed

Question

I want to include boost in my qt application in windows, So:

In my .pro file, I add:

INCLUDEPATH += D:/library/boost_1_55_0

In main.cpp

#include <boost/thread/mutex.hpp>

When build, cause this error:

Cannot open include file: 'boost/thread/mutex.hpp'

I am sure the path is correct. And it is very strange.

Creator should know when to rerun qmake
