C++ 在CMake中包含带有库的标题

c++ cmake

C++ 在CMake中包含带有库的标题,c++,cmake,C++,Cmake,我的项目中有两个实用程序库。我正在寻找为库编写CMake配置的最佳方法 /my_project --> CMakeLists.txt --> main.cpp --> /utils --> CMakeLists.txt --> common.h --> /base_c --> CMakeLists.txt --> base_c.c -->

问题是

base\u cpp

没有从

base\u c

中找到包含项。我应该如何修复配置

我设法使它与

target\u include\u目录（base\u cpp PRIVATE../base\u c）

一起工作，但这很难看，而且不应该是必需的，据介绍。

target\u include\u目录）

是您正在寻找的，但不是

PRIVATE

选项

根据

PRIVATE

选项仅适用于该目标中使用的目录，

INTERFACE

仅适用于从属目标使用的目录，

PUBLIC

同时适用于两者

我建议在/my_project/utils/base_c/CMakeLists.txt中使用

cmake_minimum_requared(VERSION 3.8)
project(my_project)

add_subdirectory(utils)

add_executable(main main.c)
target_link_libraries(main utils base_c base_cpp)

add_subdirectory(base_c)

add_library(utils)
target_sources(utils PUBLIC common.h)

add_library(base_c base_c.c)
target_sources(base_c PUBLIC base_c.h)

add_library(base_cpp base_cpp.cpp)
target_sources(base_cpp PUBLIC base_cpp.hpp)

find_library(BASEC base_c ../base_c)
target_link_libraries(base_cpp BASEC)

target_include_directories(base_c INTERFACE ${CMAKE_CURRENT_LIST_DIR})

cmake_minimum_requared(VERSION 3.8)
project(my_project)

add_subdirectory(utils)

add_executable(main main.c)
target_link_libraries(main utils base_c base_cpp)

add_subdirectory(base_c)
add_subdirectory(base_cpp)

add_library(utils)
target_sources(utils PUBLIC common.h)
target_include_directories(utils INTERFACE ${CMAKE_CURRENT_SOURCE_DIR})

add_library(base_c base_c.c)
target_sources(base_c PUBLIC base_c.h)
target_include_directories(base_c INTERFACE ${CMAKE_CURRENT_SOURCE_DIR})

add_library(base_cpp base_cpp.cpp)
target_sources(base_cpp PUBLIC base_cpp.hpp)
target_include_directories(base_cpp INTERFACE ${CMAKE_CURRENT_SOURCE_DIR})

target_link_libraries(base_cpp base_c)

通过这种方式，您可以将include目录“链接”到它所属的目标，并且依赖它的所有目标都会自动包含该目录

此外，您可能希望将公共标题移动到它们自己的子文件夹

/my\u project/utils/base\u c/base\u c/

，然后将它们作为

\include“base\u c/base\u c.h”

包含。这为标题引入了一种“名称空间”，防止来自不同项目的同名标题模棱两可。

正如@Anedar提到的，要解决这种情况，需要在库

CMakeLists.txt

中使用

PUBLIC

或

接口选项包含目录。填充INTERFACE\u的包括库目标的\u目录
，它由消费端的target\u link\u库
使用

接口包含目录的文档如何表示不需要目标包含目录
？我很好奇你是如何在没有include\u目录
或target\u include\u目录
@Tsyvarev的情况下编译单个库的，我可能完全错了。您能解释一下我如何使用库的接口\u INCLUDE\u目录吗？在CMake之后您使用哪种构建系统？生成文件？VisualStudio项目？你能检查那些文件吗？哪些目录实际上是作为包含目录传递的？我需要在base\u cpp
中的消费端做些什么吗？当前find_library
返回BASEC-NOTFOUND
您不需要在同一项目中查找库。只需使用target\u link\u库（base\u cpp base\u c）
好的，我这样做了，但它无法解析标题。也许我需要target\u include\u目录（base\u cpp）
？@voddan:它无法解析标题。
-看起来你的代码以意外的方式包含标题。使用新的CMake代码和实际错误消息更新您的问题帖子。这是一个正确的答案，但解释是无效的，因此我在需要时没有得到它：(
