## 1 基本信息
|
||
### Cmake最低版本号要求
|
||
cmake_minimum_reqired(VERSION 2.8)
|
||
|
||
### 项目信息
|
||
project(Demo1)
|
||
|
||
## 2 变量配置
|
||
|
||
### 使用mmm变量保存当前目录下所有文件
|
||
aux_source_directory(. mmm)
|
||
add_executable(Demo ${mmm})
|
||
|
||
### 将hello.cpp 赋值给SOURCE 变量
|
||
SET(SOURCE ${PROJECT_SOURCE_DIR}/src/hello.cpp)
|
||
|
||
### 收集c/c++文件并赋值给变量SRC_LIST_CPP ${PROJECT_SOURCE_DIR}代表区当前项目录
|
||
FILE(GLOB SRC_LIST_CPP ${PROJECT_SOURCE_DIR}/src/*.cpp)
|
||
FILE(GLOB SRC_LIST_C ${PROJECT_SOURCE_DIR}/src/*.c)
|
||
|
||
## 3 引入配置
|
||
|
||
|
||
|
||
### 添加子文件
|
||
add_subdirectory(math)
|
||
|
||
### 指定头文件目录
|
||
INCLUDE_DIRECTORIES(${PROJECT_SOURCE_DIR}/include)
|
||
### 指定链接库文件目录
|
||
LINK_DIRECTORIES(${PROJECT_SOURCE_DIR}/lib)
|
||
|
||
## 4 生成配置
|
||
|
||
|
||
### 指定生成目标
|
||
add_executable(Demo main.cc a.cc b.cc)
|
||
|
||
#去变量SRC_LIST_CPP 与SRC_LIST_C 指定生成libmyprint 动态库 默认生成静态库 SHARED指定生成库类型为动态库
|
||
ADD_LIBRARY(myprint SHARED ${SRC_LIST_CPP} ${SRC_LIST_C})
|
||
## 5 链接配置
|
||
|
||
#指定hello 链接库myprint
|
||
TARGET_LINK_LIBRARIES(hello myprint)
|
||
|
||
|
||
## 6 示例
|
||
### Cmake添加静态链接库
|
||
```
|
||
CMAKE_MINIMUM_REQUIRED(VERSION 3.14)
|
||
#指定项目名称
|
||
PROJECT(HELLO)
|
||
|
||
#将hello.cpp 赋值给SOURCE 变量
|
||
SET(SOURCE ${PROJECT_SOURCE_DIR}/src/hello.cpp)
|
||
|
||
#指定头文件目录
|
||
INCLUDE_DIRECTORIES(${PROJECT_SOURCE_DIR}/include)
|
||
#指定链接库文件目录
|
||
LINK_DIRECTORIES(${PROJECT_SOURCE_DIR}/lib)
|
||
|
||
#将hello.cpp生成可执行文件hello
|
||
ADD_EXECUTABLE(hello ${SOURCE})
|
||
|
||
#指定hello 链接库myprint
|
||
TARGET_LINK_LIBRARIES(hello myprint)
|
||
```
|
||
### Cmake使用动态链接库
|
||
```
|
||
#指定CMake编译最低要求版本
|
||
CMAKE_MINIMUM_REQUIRED(VERSION 3.14)
|
||
#给项目命名
|
||
PROJECT(MYPRINT)
|
||
#收集c/c++文件并赋值给变量SRC_LIST_CPP ${PROJECT_SOURCE_DIR}代表区当前项目录
|
||
FILE(GLOB SRC_LIST_CPP ${PROJECT_SOURCE_DIR}/src/*.cpp)
|
||
FILE(GLOB SRC_LIST_C ${PROJECT_SOURCE_DIR}/src/*.c)
|
||
#指定头文件目录
|
||
INCLUDE_DIRECTORIES(${PROJECT_SOURCE_DIR}/include)
|
||
#指定生成库文件的目录
|
||
SET(LIBRARY_OUTPUT_PATH ${PROJECT_SOURCE_DIR}/lib)
|
||
#去变量SRC_LIST_CPP 与SRC_LIST_C 指定生成libmyprint 动态库 默认生成静态库 SHARED指定生成库类型为动态库
|
||
ADD_LIBRARY(myprint SHARED ${SRC_LIST_CPP} ${SRC_LIST_C})
|
||
```
|
||
|
||
设置变量：set file aux_source_directory
|
||
指定目录：include_directories link_directories
|
||
生成文件 add_executable add_library
|
||
链接库 target_link_libraries |
