Hi and welcome to devnet,

I would say that your are building your project in 32bit mode while linking to a 64bit Qt

How do I change the target for my project? Particularly, I am trying to build QWT and seeing this error.

Hi and welcome to devnet,

Select the win64 console in the Visual Studio submenus and configure/build Qwt from there, you should be good to go then

[Corvin]

Qwt doesn't have a visual studio project attached, so I'm building from command line, using VS2010 compiler through qcc.

Can you please suggest, how I should pull the qwt project into Visual Studio?

You can simply use the
@
qmake
nmake
@

combo from the command line

You will also get this error on the console when you didn't select Qt with OpenGL during install (Qt 5.3.2). However when building with Qt creator it will additionally error: file not found.

If you are building from the command line, make sure you are using the 'VS2012 x64 Native Tools Command Prompt' (you'll find it under the Visual Studio menu in Start->All Programs).
