[Interest] Bluetooth library and old windows versions

[maitai]

Hello,

I have a problem with users equipped with an old version of Windows (8, 
or 7). The latest version of my app (Qt 5.11.1/MSVC 2017 based) required 
QtBluetooth but when users load the app they get a message saying:

"This Windows version does not support the required Bluetooth API. 
Consider updating to a more recent Windows (10.0.10586 or above)"

Then they press OK and the app shuts down.

I understand the message and have no problem removing BT functionalities 
for these users with old Windows versions, but my question is: can I 
avoid to build several binaries, i.e. is there a way not to load 
QtBluetooth if windows version is not recent enough ? Any other 
suggestion ?

Thanks
Philippe.
