Build error" Assignment needs exactly one word on the left hand side"

When I tried to build the project, I met the error
(command line):1: error: Assignment needs exactly one word on the left hand side.

I am using Windows 10 bits, and I followed the tutorial https://dev.qgroundcontrol.com/en/getting_started/

:fearful:

I’ve never seen that before. Does it happen at compile time or when qmake is running. Try just a Build/Run qmake to see if that works. Also is the only output you get when you build. Please provide all the build output.
