一、静态库

1.在common文件夹中的CMakeLists.txt

cmake_minimum_required(VERSION 3.10)
project(common)

# 搜索源文件
aux_source_directory(./ SRC)
set(LIBRARY_OUTPUT_PATH ${LIBPATH}) # 库生成的路径 LIBPATH

add_library(common STATIC ${SRC}) # 静态库

2.在http文件夹中的CMakeLists.txt

cmake_minimum_required(VERSION 3.10)
project(http)

# 搜索源文件
aux_source_directory(./ SRC)
set(LIBRARY_OUTPUT_PATH ${LIBPATH}) # 库生成的路径 LIBPATH

add_library(http STATIC ${SRC}) # 静态库

3.在reactor文件夹中的CMakeLists.txt

cmake_minimum_required(VERSION 3.10)
project(reactor)
aux_source_directory(./ SRC)# 搜索源文件
set(LIBRARY_OUTPUT_PATH ${LIBPATH}) # 库生成的路径 LIBPATH

add_library(reactor STATIC ${SRC}) # 静态库

4.在tcp文件夹中的CMakeLists.txt

cmake_minimum_required(VERSION 3.10)
project(tcp)

link_libraries(common http reactor)
aux_source_directory(./ SRC)# 搜索源文件
set(LIBRARY_OUTPUT_PATH ${LIBPATH}) # 库生成的路径 LIBPATH

add_library(tcp STATIC ${SRC}) # 静态库

5.在thread文件夹中的CMakeLists.txt

cmake_minimum_required(VERSION 3.10)
project(thread)
aux_source_directory(./ SRC)# 搜索源文件
set(LIBRARY_OUTPUT_PATH ${LIBPATH}) # 库生成的路径 LIBPATH

add_library(thread STATIC ${SRC}) # 静态库

6.在根目录中的CMakeLists.txt

cmake_minimum_required(VERSION 3.10)
project(HttpWeb)

# 库生成的路径
set(LIBPATH ${PROJECT_SOURCE_DIR}/lib)

include_directories(${PROJECT_SOURCE_DIR}/common)
include_directories(${PROJECT_SOURCE_DIR}/http)
include_directories(${PROJECT_SOURCE_DIR}/reactor)
include_directories(${PROJECT_SOURCE_DIR}/tcp)
include_directories(${PROJECT_SOURCE_DIR}/thread)

# 给当前节点添加子目录
add_subdirectory(common)
add_subdirectory(http)
add_subdirectory(reactor)
add_subdirectory(tcp)
add_subdirectory(thread)

link_libraries(common http reactor tcp thread -lpthread)
add_executable(server main.cpp)

# 指定输出的路径
set(HOME ${PROJECT_SOURCE_DIR}) # 定义一个变量用于存储一个绝对路径
set(EXECUTABLE_OUTPUT_PATH ${HOME}/bin) # 将拼接好的路径值设置给 EXECUTABLE_OUTPUT_PATH 变量

注意：cmake 编译c++文件时, 对‘pthread_create’未定义的引用等错误

1.或者2.这种写法
1.target_link_libraries(common http reactor tcp thread-lpthread) 

2.link_libraries(common http reactor tcp thread -lpthread)

二、动态库
