本程序使用cmake生成

cmake文件

cmake_minimum_required(VERSION 3.0.0)
project(logger CXX)
set(CMAKE_INSTALL_PREFIX "F:/Visual-Studio-practice/vscode/mySource/build")
file(GLOB SOURCE_FILE ./src/logger.cpp)
add_library(logger_static STATIC ${SOURCE_FILE})
target_include_directories(logger_static PUBLIC header)

最外层cmake

cmake_minimum_required(VERSION 3.0.0)
project(MAIN VERSION 0.1.0)
set(CMAKE_BUILD_TYPE Debug)
set(UTILS_PATH ${PROJECT_SOURCE_DIR}/utils)
add_subdirectory(utils/Log)
add_executable(MAIN main.cpp)
include_directories(${UTILS_PATH}/Log/header)
target_link_libraries(MAIN logger_static)
enable_testing()
add_test(NAME MAIN_TEST COMMAND MAIN)

目录结构如下
