At this moment (march 2014) Qt Creator doesn’t add the necessary flags for you by default. You have to do it manually.
At this moment (February 2015) qmake supports enabling C++11 (and now C++14) support via the <tt>CONFIG</tt> option in your <tt>.pro</tt> file. According to the qmake 3.0 manual that comes with Qt 5.4.0 ([http://doc.qt.io/qt-5/qmake-variable-reference.html qmake reference]) you just need to add


==In your pro file==
CONFIG += c++11


add :<br />
or


or <br />
CONFIG += c++14


==In Qt Creator build settings==
''C++11 support is enabled. This option has no effect if the compiler does not support C++11. By default, support is disabled.''
 
you can use the build input fields :
 
Project &gt; Build steps &gt; qmake section &gt;additional arguments
 
Don’t forget the “” in the input field.

At this moment (February 2015) qmake supports enabling C++11 (and now C++14) support via the CONFIG option in your .pro file. According to the qmake 3.0 manual that comes with Qt 5.4.0 (qmake reference) you just need to add 

CONFIG += c++11

or 

CONFIG += c++14

C++11 support is enabled. This option has no effect if the compiler does not support C++11. By default, support is disabled.
