CMake include path
提问by user1377000
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.
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 来处理它。
I have the directory structure:
我有目录结构：
Root
|-include
| |- foo.h
|-src
| | foo.cpp

put into root\CMakeList.txt:
放入 root\CMakeList.txt：
project(root)
include_directories(${root_SOURCE_DIR}/include)
...
you can use root_SOURCE_DIR everywhere in sub projects.
您可以在子项目中随处使用 root_SOURCE_DIR。

Use include_directories( include )for CMakeLists.txt in Root folder. Or include_directories( ${CMAKE_SOURCE_DIR}/include )from any subfolder.
使用include_directories( include )在根文件夹中的CMakeLists.txt。或include_directories( ${CMAKE_SOURCE_DIR}/include )来自任何子文件夹。
