Unable to build qt from the source (for the OpenCV)

I am trying to install OpenCV on my Windows 10 following this guide. In order to install it with my own-build libraries, I need to build qt from the source. I downloaded the latest sources from the qt page (5.6.0, I didn't find any other sources availible), but after typing

configure -release -no-webkit -no-phonon -no-phonon-backend -no-script -   no-scripttools
          -no-qt3support -no-multimedia -no-ltcg

In VS2013/VS2015 command promt, I got an error: 

Unknown option -no-webkit
Unable to detect the platform from environment. Use -platform command line
argument or set the QMAKESPEC environment variable and run configure again.

I have an option just to make everything. But I have to specify the platform. I didn't find how to do it.

Can anyone give me a hint, how to install qt correctly? I have VS 2013 and 2015. I am going to use VS2013, since VS2015 is not supported by CUDA toolkit 7.5.

Thanks,

Mikhail

Update: I was able to begin the installation process by typing configure -platform win32-msvc2013 -mp -release (although I have win64), but after accepting the licence, I got an error: execute: File or path was not found(nmake). Screenshot is attachedenter image description here

have you tried with the MSVC2013 command prompt:

configure -platform win32-msvc2013 -mp -release -no-webkit -no-phonon -no-phonon-backend -no-script -no-scripttools -no-qt3support -no-multimedia -no-ltcg

then type:

nmake

Update:

Also, before that, try adding the path to your Qt source code, with the bin folder, to the PATH variable of windows.

For instance, if your PATH variable is currently set to %SystemRoot%\system32;%SystemRoot%; and your Qt source code is at C:\dev\Qt-5.6\ then set your PATH variable to %SystemRoot%\system32;%SystemRoot%;C:\dev\Qt-5.6;C:\dev\Qt-5.6\bin

This website explains how to change the PATH variable on Windows, in case you're not familiar with it: http://www.computerhope.com/issues/ch000549.htm

Then restart the MSVC2013 Command Prompt, or Windows. I believe that should help the compilation. Let me know if it solves your problem.

What about this: -skip qtwebkit

Excluding a Qt Submodule

Configure's -skip option allows certain Qt submodules to be excluded from the Qt build. These submodules correspond to the Git submodules in the standard Qt 5 repository. Note that many packages contain multiple Qt modules. For example, to exclude Qt NFC and Qt Bluetooth from the Qt build, provide -skip qtconnectivity as the argument to configure.
