In vcxproj file for 64 bits project Qt5Version_x0020_x64 is missing

VS2012 in Qt options, name is "Qt5.2" and path is "C:\Qt\Qt5.2.1\5.2.1\msvc2012_64"

When I build a QT5 project from the Qt wizard:
With x64 configuration, I got the messagebox: “No Qt version assigned to this project for platform x64”

In vcxproj i have only Qt5Version_x0020_win32="Qt5.2", and when I add Qt5Version_x0020_x64="Qt5.2" it's OK.
