相关疑难解决方法(0)

大约一年前,我询问了CMake中的头依赖关系.

我最近意识到问题似乎是CMake认为那些头文件是项目外部的.至少,在生成Code :: Blocks项目时,头文件不会出现在项目中(源文件会出现).因此,在我看来,CMake认为这些标题是项目的外部,并且不会在依赖项中跟踪它们.

在CMake教程中快速搜索只指出include_directories哪个似乎没有我想做的...

向CMake发出信号通知特定目录是否包含要包含的标头的正确方法是什么,并且生成的Makefile应该跟踪这些标头？

我有一个C++代码的目录结构,如下所示:

|
|->include
|->src

我正在为我的代码编写一个CMakeLists.txt文件.我想明白之间的差别include_directories,并target_include_directories在CMake.

它们的用法和为了添加我应该使用的包含文件路径有什么区别？

我在我的项目中使用子模块 GitHub，现在我想使用target_include_directoriesfor 将文件包含在我的项目类中

这是我的 cmake 配置
