I have been trying to build Qt 5.6.0 for use with Visual Studio 2015 Community, but the documentation on their website and on the Qt wiki is not very specific when it comes to building it for Visual Studio. I have also tried other tutorials for building it but to no success.
Tutorials I have tried following:
https://wiki.qt.io/Building_Qt_5_from_Git
https://doc.qt.io/qt-5/windows-building.html
These are the steps that I take when attempting to build it:
Cloned the source code from the git repo to D:\Programs\qt5.
Checked out the branch I wanted. In this case it was 5.6.0.
Cloned only the essentials module subset to reduce build time.
Created a batch script to set the environment variables for the cmd session and placed it in D:\Programs\qt5:
REM Set up \Microsoft Visual Studio 2015, where <arch> is \c amd64, \c x86, etc. CALL "D:\Programs\Visual Studio 2015 Community\VC\vcvarsall.bat" amd64 SET _ROOT=D:\Programs\qt5 SET PATH=%_ROOT%\qtbase\bin;%_ROOT%\gnuwin32\bin;%PATH% REM Uncomment the below line when using a git checkout of the source repository SET PATH=%_ROOT%\qtrepotools\bin;%PATH% SET QMAKESPEC=win32-msvc2015 SET _ROOT= REM When compiling with ICU, uncomment the lines below and change <icupath> appropriately: REM SET INCLUDE=<icupath>\include;%INCLUDE% REM SET LIB=<icupath>\lib;%LIB% REM SET PATH=<icupath>\lib;%PATH%*Tried removing the SET QMAKESPEC line and it did not affect the resulting errors.
Open the Developer Command Prompt for VS2015 and navigate to D:\Programs\qt5.
Run the script in number 4.
Enter the commands to configure the Qt5 build.
configure -developer-build -opensource -confirm-license -nomake tests -nomake examples -mp -skip qtwebengine -skip qtwebchannel*Is there a way to use the configure command to only build the essentials module subset?
Enter the command to build Qt.
nmakeI get this error when I try to build it:

I have tried searching this error to find a fix, but so far I haven't been able to get much information about it at all.
Any help on the subject would be greatly appreciated, thanks.
SET QMAKESPEC=win32-msvc2013looks wrong, try withSET QMAKESPEC=win32-msvc2015. Or just don't set the mkspec explicitly at all. (not entirely sure if that works, but worth a try) – Frank Osterfeld
