[PyQt] pyqtsysroot and unresolved __thiscall QObject symbols

[Patrick Stinson]

Has anyone run into QObject unresolved symbols like this related to your own source files when linking a pyqtproject built on windows using qt built with pyqtdeploy-sysroot? I am using VS 2017.

It looks like maybe a define or header mismatch for the calling convention?
