So I am on:
trying to build:
qt5.10.1
with QtWebEngine
jom.exe -j4
and during the QtWebEngine
build process, this happened:

I found this forum with a slightly active/recent question asking about this same issue here:
Is there anything I can do from this point to fix this?
Downgrading my version of VS to 2015 allowed me to bypass this compiler error and compile QT successfully.
