项目代码架构

在project目录下的树结构如下：

 1 root@u18:~/cp/project# tree
 2 .
 3 ├── 3rd_lib　　　　　　//存放 第三方库 的目录
 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
