[PyQt] pyqtdeploy-sysroot: Error compiling qt5.11.2 on windows

[Patrick Stinson]

Looks like this has something to do with a ridiculously low MAX_PATH limitation to the number of chars allowed in a file path which is compiled into cl.exe:

There is a similarly related bug report here:

What a bummer...
