[PyQt] Building PyQt5 for pyqtdeploy on windows - nmake error

[Chandrakant Gopalan]

Hello,
I am evaluating pyqtdeploy so that we can use it to build our PyQt5-based app for different platforms. As a first step, I am trying to build our application via pyqtdeploy on a windows 10 host, targeting windows platforms.
I am in the process of statically building packages. I am following the steps on http://pyqt.sourceforge.net/Docs/pyqtdeploy/static_builds.html
I have been able to statically build Python. And also build sip. But I am having trouble building PyQt.

I was able to run "pyqtdeploycli --package pyqt5 configure" and it generated the cfg file.
Then I ran "python configure.py --static --sysroot=%SYSROOT% --no-tools --no-qsci-api --no-designer-plugin --no-qml-plugin --configuration=pyqt5-win.cfg"
and i was able to generate the makefile.
But when I run "nmake" I get this error:

nmake worked when I built sip. Not sure why this is happening here. Can anyone please help?

Thanks
