mingw gcc编译cpp-tests，cocos\audio里一堆未定义错误，发现AudioEngine.cpp没有加进CMakeLists.txt里，于是把CMakeLists.txt改成这样
if(WINDOWS)
set(COCOS_AUDIO_SRC
audio/AudioEngine.cpp
audio/win32/AudioCache.cpp
audio/win32/AudioCache.h
audio/win32/AudioEngine-win32.cpp
audio/win32/AudioEngine-win32.h
audio/win32/AudioPlayer.cpp
audio/win32/AudioPlayer.h
audio/win32/SimpleAudioEngine.cpp
audio/win32/MciPlayer.cpp
audio/win32/MciPlayer.h
)
继续编译，报以下错误
