Error linking with folly when building Proxygen on Mac OS

[VinothParamaguru]

Hi

Could someone please help me with the errors below. I'm trying build the EchoServer that comes as part of proxygen.
I have not installed proxygen from the source, but have used vcpkg to link the dependencies.

"EchoService::EchoHandler::EchoHandler(EchoService::EchoStats*)", referenced from:
EchoHandlerFactory::onRequest(proxygen::RequestHandler*, proxygen::HTTPMessage*) in EchoServer.cpp.o

I'm using Mac OS 13.7.1 (22H221)

Thanks.
