我是 C++ 和 CMake 的新手，并开始了一个大项目。我使用 VScode 作为我的文本编辑器和 CMake 作为我的构建工具。

问题是我可以在所有具有相同名称的源文件的头文件中包含“SFML/Graphics.hpp”，但如果我包含“SFML/Graphics.hpp”或任何其他包含“SFML/Graphics”cmake 不会构建并返回错误。

这是我的代码

add_subdirectory(Systems)

add_library(ECS EcsManager.cpp System.cpp )

target_link_libraries(ECS ECS_SYSTEMS)

CMakeLists.txt - 系统

add_library(ECS_SYSTEMS MovementSystem.cpp RenderableSystem.cpp)

Cmake 输出的错误是：'SFML/Graphics.hpp': No such file or directory MSVC(C1083)

如果我在任何“任何”组件类中包含“SFML/Graphics.hpp”，则会出现错误任何“组件类（或任何其他仅标头）都会出错。

我在stackoverflow中找不到任何解决方案。

不要判断我的文件夹结构，当错误第一次出现时它是不同的......而不是我更改为查看 CMake 是否会构建。

您需要将 SFML 包含目录添加到包含目录列表中。

后

find_package(SFML 2.5.1 COMPONENTS REQUIRED graphics window system network audio)

添加行

include_directories(${SFML_INCLUDE_DIR})
