Failed to load Plugins/MqttUtilities/Binaries/Win64/mosquitto.dll (GetLastError=126)

[ennorehling]

When I package my game abd run the packaged build, these messages appear in the log:

LogWindows: Failed to load '../../../HalfLifeThree/Plugins/MqttUtilities/Binaries/Win64/mosquitto.dll' (GetLastError=126)
LogWindows: File '../../../HalfLifeThree/Plugins/MqttUtilities/Binaries/Win64/mosquitto.dll' does not exist
LogWindows: Failed to load '../../../HalfLifeThree/Plugins/MqttUtilities/Binaries/Win64/mosquittopp.dll' (GetLastError=126)
LogWindows: File '../../../HalfLifeThree/Plugins/MqttUtilities/Binaries/Win64/mosquittopp.dll' does not exist

The DLLs are in 'Binaries\Win64', the packaged build has no 'Plugins/MqttUtilities' directory, so why is Unreal even looking for them here?

Everything still seems to work, so it doesn't seem like this is a critical message, but I would still like to get rid of it.
