使用包含和源路径进行CMake - 基本设置

Question

我正在尝试设置一个看起来像我自己的项目的测试项目,只是为了让事情先行,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,但是当我有inc和src文件夹时,我无法找到如何设置它？CMakeLists.txt文件看起来如何？我会在每个项目文件夹中有一个/,一个吗？好像我不需要在inc和src文件夹中有一个？

Answer 1

CMakeLists.txt每个源子目录都需要一个.您的结构应如下所示:

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

内容root/CMakeLists.txt:

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

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

add_subdirectory(src)

内容LibProject/src/CMakeLists.txt:

# 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)

内容MainProject/src/CMakeLists.txt:

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

Answer 2

你可以这样做.

• MainProject目录中的CMakeLists.txt:

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

• LibProject/src目录中的CMakeLists.txt:

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

• MainProject/src目录中的CMakeLists.txt:

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

Answer 3

就我而言，我想用一个CMakeList做到这一点。它为我工作。我添加我的解决方案，以防任何人使用。

这是我的情况：

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

我的CMakeLists.txt必须包含以下主要部分：

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

^使.cpp文件能够在包含文件夹中添加头。

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

^只需添加这些文件夹中的内容即可。
