[PyQt] Pyqtdeploy - build pyqt app on Windows

[Mạnh Tú Vũ]

Hello,

I'm trying to build my PyQt application on Windows and I'm not sure that I
understand the way it works. I have built my application into a .exe binary
file but when I was trying to run, it threw an exception of:

I suspect, the Qt application was trying to find Qt5Core.dll library,
however, I see in the Makefile.Release, we had already
included  sysroot-win-32\qt\lib\Qt5Core.lib into the application. So, why
do we need the .dll library again?

I have tried to run the app using Qt command line and see it worked.
Because the required libraries are already included in the PATH env. So,
does it mean that I have to distribute the .dll libraries with my
application as well?

Thank you,

Tu
