I am working on a Blackberry 10 app using wikitude SDK. I am using the documentation on the website and adding the libraries to the project . When the project is built , I am getting an error with "ntox86-ld" . I am new to this and cannot debug the error. The error is:

please look into the issue . I am new to this technology I am trying to implement Augmented Reality in bb10 using wikitude , please help I am stuck here?
You are building the target "Simulator-Debug" which is not supported by Wikitude SDK. You will need to build for a device. Change the "Build configuration" under Debug/Run Configurations to "Device-Debug" or "Device-Release".

I check multiple times and every folder exists.
Everything is run on Ubuntu inside a docker container with this command.
make -f Makefile.Release
As BoBTFish said, you can't have \ (backslashes) in your path. What you have to do here is to change Widget\Inventory\inventoryplusbutton.h into Widget/Inventory/inventoryplusbutton.h and make sure it exists.

I have no clue why it failed to compile the code saying File format not recognized. Is it the same mistake as in g++ output: file not recognized: File format not recognized?
Thank you for your help in advance!
Comment:
I followed the following questions too but I want to install it using the zip file - so I know what is installed.
Can't configure pyQt
How to install SIP & PyQT on windows 7
How did you configure SIP? You need to choose a configuration option (see documentation in the docs file of the SIP archive). I got this to work once I chose --platform win32-g++.
I am working on a network management application with Qt and I chose to use Wt for UI, because with it I will not have to deal with any of web parts (PHP, AJAX, HTML/CSS) and it'll be usable on all platforms.
I successfully managed to compile and run examples using cmake. Although I am used to QtCreator IDE and qmake I would rather use that for development and compiling.
I got stuck trying to compile "wtwithqt" example in QtCreator(qmake). I've been searching everywhere for some guide how to compile it with qmake. However I found nothing helpful.
Here is my .pro file.
testWt.pro

QT -= gui
TARGET = helloqt
CONFIG += console no_keywords

Any help is appreciated! Thanks in advance!
