testee_client gave LNK2019 for compress/decompress/Init

[ehaerim]

Dear Peter Thorson

I have been trying to compile and link one of your websocket++ examples called testee_client.
I am getting the following link error and I couldn't figure out how to fix it. They seem to be about
compress, decompress, Init, etc. Please help.

In order to use compression/permessage deflate extension you will need to link to the zlib library. All the unresolved symbols referenced here are in that library.
