When I use Windows WASAPI to get the audio device properties, the following 3 properties compiled good,

PKEY_Device_FriendlyName
PKEY_Device_DeviceDesc
PKEY_DeviceInterface_FriendlyName

but when I use PKEY_AudioEndpoint_FormFactor, the Visual Studio 2017 prompts the following error error LINK2001 "cannot resolve symbol PKEY_AudioEndpoint_FormFactor"

Can anyone help what lib is missed for PKEY_AudioEndpoint_FormFactor in the link setting of visual studio project?
