Cannot statically build x64 version of QT (LNK1112 module machine type conflicts)

I want to create a static application with QT(5.4.1) and compile it with visual studio 2013 (with QT Add-in) in a x64 environment.

I downloaded the most recent source code and compiled it using VS well buried x64 command prompt. I made sure the platform was 64-bits in Task Manager→Details→Platform. Here is the configure command I ran:

**configure** -debug-and-release -opensource -platform win32-msvc2013 -static -nomake examples -nomake tests

Once I compile it with jom and properly link it to my project, I can only build it with the win 32 configuration. When I try the x64 configuration, I get:

Error   3   error LNK1112: module machine type 'X86' conflicts with target machine type 'x64'   D:\....\Qt5Widgets.lib(qwidget.obj)

It obviously means my binaries are built in a 32 bits format. If it's the case, I have no idea how to build them in x64. Any Ideas? I have scoured the internet and many have reached my dead end without getting help.

This link might help, even though it's for an older version of Qt.

Basically, you have to run your configure & build process in a 64 bit MSVC command prompt for it to build a 64 bit binary. I'd also guess that it's a good idea to start with a clean Qt environment if you have to build both 32 and 64 bit version.
