Qt 5.3.0, msvc-2013, configure -prefix, multiple directories problem

Hi, i’m compiling Qt 5.3.0, Windows 7, msvc2013, using this config: configure -prefix D:\libraries\Qt5.3.0-compiled -debug-and-release -opensource -confirm-license -platform win32-msvc2013 -c++11 -icu After compiling and installing i get three directories : Qt5.3.0-compiled, Qt5.3.0 and Qt5.3.0-msvc2013_x86. Some include files are in Qt5.3.0\include directory and some are in the Qt5.3.0-compiled\include and in Qt5.3.0-msvc2013_x86\include there are the QtDeclarative includes. Why ?. I want one directory specified in -prefix. Thanks.
