使用CMake構建PubNub C++

我試圖從使用CMake的PubNub C++ git repository中編譯一個樣本，將它包含在我的一個項目中。使用CMake構建PubNub C++

作爲測試，我選擇編譯從provided Makefile命名 cancel_subscribe_sync_sample樣品。

使用Makefile，它編譯時沒有任何錯誤。

這是我想出了CMakeLists（我在CMake的不是專家）：

cmake_minimum_required(VERSION 3.4) 
project(untitled) 

set(CMAKE_CXX_FLAGS "-Wall -std=c++11") 

set(SOURCE_FILES cancel_subscribe_sync_sample.cpp) 

set(PUBNUB_FILES c-core/core/pubnub_coreapi.c 
     c-core/core/pubnub_coreapi_ex.c 
     c-core/core/pubnub_ccore.c 
     c-core/core/pubnub_netcore.c 
     c-core/lib/sockets/pbpal_sockets.c 
     c-core/lib/sockets/pbpal_resolv_and_connect_sockets.c 
     c-core/core/pubnub_alloc_std.c 
     c-core/core/pubnub_assert_std.c

     c-core/posix/pbpal_posix_blocking_io.c 
     c-core/posix/monotonic_clock_get_time_posix.c) 

include_directories(c-core/posix) 
include_directories(c-core/cpp) 
include_directories(c-core/core) 

add_definitions(-DPUBNUB_THREADSAFE) 

add_executable(untitled ${SOURCE_FILES} c-core/core/pubnub_ntf_sync.c c-core/cpp/pubnub_futres_sync.cpp ${PUBNUB_FILES}) 
link_libraries(untitled pthread rt)

在Ubuntu克利翁使用它，編譯失敗：

我真不不明白爲什麼。例如，在文件pubnub_alloc_std.c中定義了函數pubnub_alloc（）。

這使我瘋狂......我在這裏做錯了什麼？

謝謝！
