我知道周围有很多类似的问题，但大多数都能解决包括内存在内的问题。我以前遇到过这个问题，上次这个解决方案似乎解决了这个问题，但这次没有。
我正在和一个使用macbook的伴侣一起做一个大学项目，我使用Windows 10，但通常不是问题。我们正在与Clion和Cmake合作，我们使用SFML库。
目前，这个项目在她的macbook上运行得很好，但在我的macbook上没有运行。代码是相同的，目录是相同的并且位于相同的位置。上次我遇到这个问题，我解决了，正如我所说的，在我们的ResourceHolder.h文件中包括<memory>。现在我无法将该文件包含在我们的Character.h文件中(不知道为什么，就像他们找不到对方一样，但CMakelist.txt包含了我们所有的文件(。当然，我试着浏览我们的文件树，但没有成功。如果我在Character.h中包含memory，那么项目将运行到96%，然后会出现许多未定义的引用错误。
有人能帮我或解释我如何用共享指针一次性解决这个问题吗？我想知道为什么我不能将该文件(ResourceHolder(也包含在同一项目的另一个文件中。
EDIT：编译器是MinGW，下面的代码不包括
编辑<2> ：我清理了很多嵌套的#include，然后我像一样更改了Cmake
target_link_libraries(BlackRose core ${SFML_LIBRARIES} )
现在似乎奏效了
这是CMakeLists.txt文件：

谢谢你的耐心和帮助。
尝试用set (CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")替换set(CMAKE_CXX_STANDARD 11)我以前也遇到过同样的问题，这一行肯定有帮助，也许CMAKE_CXX_STANDARD由于某种原因没有解决任何标志。
