cmake_minimum_required(VERSION 3.10)
project(WebServer)

# ====================================================
# 1. 基础设置
# ====================================================
# 统一使用 C++17 (兼容性更好，涵盖 C++14)
set(CMAKE_CXX_STANDARD 17)
set(CMAKE_CXX_STANDARD_REQUIRED ON)

# ====================================================
# 2. 依赖查找与引入
# ====================================================

# [Spdlog] 日志库 (源码编译方式)
# 确保 third_party/spdlog 目录存在
if(EXISTS "${CMAKE_CURRENT_SOURCE_DIR}/third_party/spdlog")
    add_subdirectory(third_party/spdlog)
else()
    message(WARNING "spdlog source not found in third_party!")
endif()

# [MySQL] 数据库依赖
find_package(PkgConfig REQUIRED)
pkg_check_modules(MYSQL REQUIRED mysqlclient)

# [Threads] 线程库
find_package(Threads REQUIRED)

# ====================================================
# 3. 源文件与生成目标
# ====================================================

# 自动递归查找 src 下所有的 .cpp 文件
# (包含 main.cpp, net/, server/, base/, http/, app/ 等所有子目录)
file(GLOB_RECURSE SRC_FILES "src/*.cpp")

# 生成可执行文件 (仅定义一次)
add_executable(WebServer ${SRC_FILES})

# ====================================================
# 4. 头文件包含路径
# ====================================================
target_include_directories(WebServer PUBLIC
    ${CMAKE_SOURCE_DIR}/include        # 项目头文件
    ${CMAKE_SOURCE_DIR}/third_party    # 第三方库 (如 nlohmann/json)
    ${MYSQL_INCLUDE_DIRS}              # MySQL 头文件
)

# ====================================================
# 5. 链接库
# ====================================================
target_link_libraries(WebServer
    PRIVATE
    spdlog::spdlog         # spdlog 库
    Threads::Threads       # 线程库
    ${MYSQL_LIBRARIES}     # MySQL 客户端库
    dl                     # 动态链接库 (MySQL依赖)
)

# ====================================================
# 6. 构建后操作 (资源复制)
# ====================================================
# 编译成功后，自动将 resources 文件夹复制到 build 目录
# 这样程序运行时可以直接读取 resources/config.json
add_custom_command(TARGET WebServer POST_BUILD
    COMMAND ${CMAKE_COMMAND} -E copy_directory
        ${CMAKE_SOURCE_DIR}/resources
        ${CMAKE_CURRENT_BINARY_DIR}/resources
    COMMENT "Copying resources to build directory..."
)
