It fails with a linker error, unresolved symbols.  See the dump of the entire script at the bottom of this email.  Sorry that it's quite long, I'm running it in full verbose mode.

Try installing the program to fix this problem".  But the first time it gave me that error it was complaining about another DLL, QtVisualization.dll if I recall correctly.  I don't know if this is a related problem, or a separate problem.

Or, if there's a known-good recipe for the .PDY file that would work with what components I have?   I've attached my sysroot.json and the pyqt-demo.pdy file to the email.  Note that the only thing I've changed since my last email was the version of OpenSSL, I changed the source from version 1.1.1a to 1.0.2q because Python 3.5.1 uses 1.0.2d thru j or so.

I suggest you get the demo working without changing *anything*, then change one thing at a time until you have the setup you want.
