CMake 包含路径 [英] CMake include path

问题描述

在 C++ 项目中，我会将头文件作为项目源目录的后代包含在内，而不使用 UNIX 目录快捷方式.或者 .. .我不确定如何配置 cmake 以使用它.

In a C++ project, I would to include the header files as as descendants of the project's source directory without use of UNIX directory shortcuts . or .. . Im not sure how to configure cmake to work with that.

我有目录结构:

Root
|-include
| |- foo.h
|-src
| | foo.cpp

推荐答案

放入rootCMakeList.txt:

put into rootCMakeList.txt:

project(root)
include_directories(${root_SOURCE_DIR}/include)
...

您可以在子项目中的任何地方使用 root_SOURCE_DIR.

you can use root_SOURCE_DIR everywhere in sub projects.
