CMake包含和源路径-基本设置

CMake with include and source paths - basic setup

本文关键字：设置 路径 包含 CMake      更新时间：2023-10-16

我正在尝试建立一个测试项目，看起来像我自己的项目，只是为了让事情首先工作，它看起来像这样:

/MainProject/inc/main.h
/MainProject/src/main.cpp
/LibProject/inc/test.h
/LibProject/src/test.cpp

我找到了一些教程，但我不知道如何设置这当我有inc和src文件夹?CMakeLists.txt文件看起来如何?我要在每个项目文件夹里放一个吗?似乎我不需要有一个在inc和src文件夹?

每个源子目录都需要一个CMakeLists.txt。你的结构应该像这样:

root
|-MainProject
| |-inc
| | '-main.h
| |-src
| | |-main.cpp
| | '-CMakeLists.txt
| '-CMakeLists.txt 
|-LibProject
| |-inc
| | '-test.h
| |-src
| | |-test.cpp
| | '-CMakeLists.txt
| '-CMakeLists.txt
'-CMakeLists.txt

root/CMakeLists.txt含量:

project(MyProject)
add_subdirectory(MainProject)
add_subdirectory(LibProject)

LibProject/CMakeLists.txt和MainProject/CMakeLists.txt含量:

add_subdirectory(src)

LibProject/src/CMakeLists.txt内容:

# Notice name prefix of this variable, set by CMake according
# to value given with "project()" in the root CMakeLists.txt.
include_directories(${MyProject_SOURCE_DIR}/LibProject/inc)
add_library(LibProject test.cpp)

MainProject/src/CMakeLists.txt内容:

include_directories(${MyProject_SOURCE_DIR}/MainProject/inc)
# I assume you want to use LibProject as a library in MainProject.
include_directories(${MyProject_SOURCE_DIR}/LibProject/inc)
link_directories(${MyProject_SOURCE_DIR}/LibProject/src)
add_executable(MainProject main.cpp)
target_link_libraries(MainProject LibProject)

然后配置和构建:

$ cd root
$ mkdir build
$ cd build
$ cmake ..
$ make

你可以这样做:

  • CMakeLists.txt在你的MainProject目录:

    project(MainProject)
add_subdirectory(LibProject/src)
add_subdirectory(MainProject/src)

  • CMakeLists.txt在LibProject/src目录下:

    include_directories(${PROJECT_SOURCE_DIR}/LibProject/inc/)
add_library(LibProject test.cpp)

  • CMakeLists.txt在你的MainProject/src目录下:

    include_directories(${PROJECT_SOURCE_DIR}/MainProject/inc/)
add_executable(MainProject main.cpp)
target_link_libraries(MainProject LibProject)

在我的情况下，我想用单个CMakeList来做。这对我很有效。我把我的解决方案加进去，以防有人用。

我是这样做的:

My structure:
Project
|CMakeLists.txt
|-src
| |*.cpp
| |*.c
|-include
| |*.hpp
| |*.h

我的CMakeLists.txt必须主要部分:

include_directories(
        ${PROJECT_SOURCE_DIR}/include
        ${PROJECT_SOURCE_DIR}/src
)

^允许。cpp文件在include文件夹中添加头文件。

file(GLOB all_SRCS
        "${PROJECT_SOURCE_DIR}/include/*.h"
        "${PROJECT_SOURCE_DIR}/include/*.hpp"
        "${PROJECT_SOURCE_DIR}/src/*.cpp"
        "${PROJECT_SOURCE_DIR}/src/*.c"
        )

^把文件夹里的东西都加进去。

add_executable(MyTarget ${all_SRCS})

^从所有源列表中构建目标
