[Boost-users] [coroutines2] Building coroutines2 examples

Hi,

  I'm trying to build the Boost 1.59 coroutine and coroutine2 examples.
I built boost with b2 (complete build)  and am using CMake to generate a
VC2015 project to build the samples.

All the coroutine samples build and run just fine, but I get *linking*
errors with the coroutine2 samples.

My CMakeLists.txt file is straightforward, just find boost, include the
headers and link to the boost libs:

project (coroutines-samples)
cmake_minimum_required(VERSION 2.8)

find_package(Boost REQUIRED)
include_directories(${Boost_INCLUDE_DIR})
link_directories(${Boost_LIBRARY_DIRS})

What am I doing wrong?
