[CMake] FindBoost not setting Boost_LIBRARIES

[Andrew Maclean]

This works for me:

#-----------------------------------------------------------------------------
# Boost
  # The automatic linking, uses the static version of the libraries.
  if(WIN32)
    set(Boost_USE_STATIC_LIBS ON)
  endif(WIN32)

  # Uncomment and edit if CMake cannot find boost.
  set(Boost_ADDITIONAL_VERSIONS "1.43" "1.43.0" "1.42" "1.42.0")
  find_package(Boost REQUIRED COMPONENTS system filesystem )
  if ( Boost_FOUND )
    include_directories(${Boost_INCLUDE_DIRS})
    add_definitions(${Boost_LIB_DIAGNOSTIC_DEFINITIONS})
    # Remember to include ${Boost_LIBRARIES} in the
target_link_libraries() statement
  endif ( Boost_FOUND )


Regards
   Andrew
