The sample code I got from cpp-netlib won't compile

  This is a part of the 'Hello World' example. It's used to
  demonstrate how easy it is to set up an HTTP server.  All we do in
  this example is create a request handler and run the server.

I suspect it's something to do with not linking my libraries correctly. This is the error I get when I run make. I can run this example fine off the cpp-netlib folder but when I try to copy that code and put it in my own folder, it doesn't compile.

Note in the CMakeLists.txt under root directory, there is 1 line for Asio

include_directories(deps/asio/asio/include)

add it to your project, then it will work
