项目代码架构

在project目录下的树结构如下：

 1 root@u18:~/cp/project# tree

 2 .

 4 │   ├── libvirt-lxc.so

 5 │   ├── libvirt-qemu.so

 6 │   └── libvirt.so

 7 ├── build　　　　　　 //执行Cmake ..的目录

32 5 directories, 23 files

　　CMakeList文件内容如下：

 1 cmake_minimum_required (VERSION 2.6)

 2 

 3 #PROJECT(projectname [CXX] [C] [Java])  编译语言

 4 project (Libvirt CXX)

 5 

 6 #The version number

 7 set (Libvirt_VERSION_MAJOR 1)

 8 set (Libvirt_VERSION_MINOR 0)

 9 

10 #configure a header file to pass some of  the source code

11 configure_file (

12     "${PROJECT_SOURCE_DIR}/src/LibvirtConfig.h.in"

13     "${PROJECT_BINARY_DIR}/src/LibvirtConfig.h"

14     )

15 

16 # equal to echo in shell

17 MESSAGE(STATUS "This is source dir: " ${PROJECT_SOURCE_DIR})

18 MESSAGE(STATUS "This is binary dir: " ${PROJECT_BINARY_DIR})

19 

20 #add sub dir  and find CMakeList.txt in the sub dir, done it

21 #ADD_SUBDIRECTORY(subdir)

22 

23 #将一个文件下的编译用的源文件添加到一个宏列表中

24 #AUX_SOURCE_DIRECTORY(. SRC_LIST)

25 #只将.cc .cpp .c 的文件添加到SRC_LIST中，.h除外

26 

27 

28 #将.h文件也添加进来，使用

29 INCLUDE_DIRECTORIES("${PROJECT_BINARY_DIR}/src")

30 FILE(GLOB_RECURSE SOURCE_FILE ./src/*.cpp  ./src/*.c)

31 FILE(GLOB_RECURSE HEADER_FILE *.h  *.hpp)

32 

33 MESSAGE(STATUS "This is source dir: " ${SOURCE_FILE})

34 #MESSAGE(STATUS "This is header dir: " ${HEADER_FILE})

35 #add the binary tree to the search path for include files so that we will find LibvirtConfig.h

36 #include_directories ("${PROJECT_BINARY_DIR}/src", "${PROJECT_BINARY_DIR}/INCLUDE/libvirt")

37 

38 #add the 3rd_lib

39 #link_directories("${PROJECT_BINARY_DIR}/3rd_Lib")  

40 FILE(GLOB_RECURSE LIB_FILE libvirt.so*)

41 

42 MESSAGE(STATUS "This is 3rd_lib file : " ${LIB_FILE})

43 

44 #add the executable

45 add_executable(Libvirt ${SOURCE_FILE})

46 

47 #link 

48 TARGET_LINK_LIBRARIES(Libvirt ${LIB_FILE})

操作步骤：

　　1、进入build目录，执行cmake .. (因为CMakelist文件在上一级目录中)，生成Makefile文件

　　2、执行make即可
