下面通过一个小例子来说明cmake编译一个c++项目，生成可执行文件：

整理目录结构：

CMakeLists.txtaddlibbuildmain.cpp

电脑上没有tree命令，也不大敢截图，将就着看看，其中build是cmake编译指定的路径，addlib下面也有一个头文件和源文件，还有一个CmakeLists.txt,可以看下：

CMakeLists.txtlibrary.cpplibrary.h

先看各个文件的代码：

addlib/library.h:

#ifndefCPPPROJECT_LIBRARY_H
#defineCPPPROJECT_LIBRARY_H

intacc_add(int);

#endif

addlib/library.cpp:

#include"library.h"
#include

voidhello(){
std::cout<<"helloworld"<
addlib/CMakeLists.txt:
cmake_minimum_required(VERSION3.10)
project(accliblibrary)

set(CMAKE_CXX_STANDARD11)

add_library(accliblibrarySHAREDlibrary.cpplibrary.h)#诉生成一个库文件。
main.cpp:
#include
#include
#include"addlib/library.h"
usingnamespacestd;
intmain(){
intn=10;
intans=acc_add(n);
cout<<"1+....+"<
CMakeLists.txt:
cmake_minimum_required(VERSION3.10)
project(cppproject)

set(CMAKE_CXX_STANDARD11)

add_subdirectory(acclib)


add_executable(cppprojectmain.cpp)#生成一个可执行的文件

target_link_libraries(cppprojectaccliblibrary)
下面就是编译该项目，生成可执行文件：

cdbuild/
cmake..
