cmake常用

部分一：

cmake_minimum_required(VERSION 3.16)

project(Demo VERSION 0.1.0 LANGUAGES CXX)

set(CMAKE_CXX_STANDARD 17)
set(CMAKE_CXX_STANDARD_REQUIRED ON)

if(MSVC)
    add_compile_options(/utf-8)
    #add_compile_options(/source-charset:utf-8)
    add_definitions(-D_CRT_SECURE_NO_WARNINGS)
    add_definitions(-D_WIN32_WINNT=0x0601)
endif()

include_directories(C:/local/cxxLibrary/include)
add_executable(Demo main.cpp)

部分二：

if (CMAKE_CXX_COMPILER_ID MATCHES "GNU" AND CMAKE_SYSTEM_NAME MATCHES "Windows")
    MESSAGE(STATUS "Csp Add MinGW Param.")
    add_compile_options(-finput-charset=utf-8)
    add_compile_options(-fexec-charset=gbk)
    set(COMPILER_ID "mingw")
    get_filename_component(CXX_COMPILER_PATH ${CMAKE_CXX_COMPILER} DIRECTORY)
    set(MINGW32_DLLS 
    "${CXX_COMPILER_PATH}/libgcc_s_dw2-1.dll"
    "${CXX_COMPILER_PATH}/libstdc++-6.dll"
    "${CXX_COMPILER_PATH}/libwinpthread-1.dll")
    install(FILES ${MINGW32_DLLS} DESTINATION bin)
endif()

部分三：

list(APPEND CMAKE_PREFIX_PATH ${CMAKE_CURRENT_LIST_DIR}/3rd/binary/mingw64)

set(LIBRARY_OUTPUT_PATH ${CMAKE_BINARY_DIR}/lib/${CMAKE_BUILD_TYPE})
set(CMAKE_RUNTIME_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/bin/${CMAKE_BUILD_TYPE}/)

CXX常用

#pragma once

#if defined(_WIN32) || defined(_WIN64)
#ifdef LIBRARY_EXPORTS
#define EXPORT_API __declspec(dllexport)
#else
#define EXPORT_API __declspec(dllimport)
#endif
#else
#define EXPORT_API __attribute__((visibility("default")))
#endif

#ifdef __cplusplus
extern "C" {
#endif

EXPORT_API int add(int a, int b);

#ifdef __cplusplus
}

一些小说明

spdlog

如果使用WriteConsoleW，定义：

add_definitions(-DSPDLOG_UTF8_TO_WCHAR_CONSOLE)
add_definitions(-DSPDLOG_WCHAR_TO_UTF8_SUPPORT)

# 如果需要Debug和Trace生效，还需要
add_definitions(-DSPDLOG_ACTIVE_LEVEL=SPDLOG_LEVEL_TRACE)

如果自定义等级名称：

#if __cplusplus >= 201703L
#include <string_view>
using namespace std::string_view_literals;
#define SPDLOG_LEVEL_NAMES {"TRACE"sv, "DEBUG"sv, "INFO"sv, "WARN"sv, "ERROR"sv, "CRIT"sv, "OFF"sv}
#else
#define SPDLOG_LEVEL_NAMES {"TRACE", "DEBUG", "INFO", "WARN", "ERROR", "CRIT", "OFF"}
#endif
