[QGIS-Developer] Pyinstaller to create stand alone app

[Benjamin Jakimow]

Hi Luke,

it looks like your QGISenv.bat does not add the QGIS internal plugin 
folder to the PYTHONPATH.

You may use something like:

set PYTHONPATH=^
%OSGEO4W_ROOT%\apps\%QGIS_ENV%\python;^
%OSGEO4W_ROOT%\apps\%QGIS_ENV%\python\plugins;^
%PYTHONPATH%

where OSGEO4W_ROOT is the path to where your QGIS is installed, and 
QGIS_ENV the release type, e.g. "qgis" or "qgis-ltr"

Greetings, Benjamin
