# This script is based on the implementation of windeployqt for qt5.7.1
#
# Qt's plugin deployment strategy is that each main Qt Module has a hardcoded
# set of plugin subdirectories. Each of these subdirectories is deployed in
# full if that Module is referenced.
#
# This hardcoded list is found inside qttools\src\windeployqt\main.cpp. For
# updating, inspect the symbols qtModuleEntries and qtModuleForPlugin.

# Note: this function signature and behavior is depended upon by applocal.ps1
