[PyQt] error building QtNfc

[scott zimmerman]

Hello,
 
I'm using PyQt 5.5.1, Anaconda 3.5.1, Qt 5.6, Visual Studio 2015, and Windows 10. To get PyQt configure.py to work I did the following:
1. The script finds qmake.exe from Qt4 in Anaconda *before* it checks for the --qmake option so I hard-coded the qmake.exe path inside the script to be Qt5.
2. I added C:\Qt\5.6\msvc2015_64\bin to the path environment so qmake could find other programs.
3. I opened the VS2015 x64 command shell to run python configure.py so the x64 version of nmake and cl are used.
 
After configure.py ran successfully, I ran nmake in the pyqt folder. After building many files, it got the fatal error below.
 
Is there a workaround? Or some way I could continue without QtNfc.dll?
