CMake是一个跨平台的自动化建构系统,它使用一个名为 CMakeLists.txt 的文件来描述构建过程。CMake可以运行在Windows和Linux环境下，根据配置的编译器不同，生成符合所在操作系统的 Makefile 文件，在Windows下可以生成VS的工程文件系统。
将 CMake/bin 目录加入到系统环境变量Path 中

这是一个将开放式基金数据转换为 MIDI音乐的 C++ 程序示例。该程序将基金净值映射为 MIDI音符的音高

/funds/data/660008.csv 文件开头：
date,jz,ljjz
2016-01-04,1.1141,1.1141
2016-01-05,1.1161,1.1161
2016-01-06,1.1350,1.1350

1. midifile 项目--目录结构

2025/03/31  21:18    <DIR>          .
2025/03/31  21:18    <DIR>          ..
2025/03/18  00:31               185 .gitignore

2025/03/18  00:31    <DIR>          visual-studio

2.编写 tools/fund2mid.cpp 程序，如下

#include <iostream>
#include <fstream>
#include <vector>
#include <string>
#include <cstring>
#include <algorithm>
#include <sstream>
#include "MidiFile.h"using namespace std;
using namespace smf;// CSV 数据结构/
struct FundData {string date;double jz;
};// 解析 CSV 文件（适配三列格式）
vector<FundData> readCSV(const string& filename) {vector<FundData> data;ifstream file(filename);string line;// 跳过标题行getline(file, line);while (getline(file, line)) {// 使用字符串流分割三列stringstream ss(line);string date, jzStr, ljjzStr;// 按逗号分割字段getline(ss, date, ',');getline(ss, jzStr, ',');getline(ss, ljjzStr); // 第三列不需要使用if (date > "2024-01-01") {try {double jz = stod(jzStr);data.push_back({date, jz});} catch (const exception& e) {cerr << "解析错误: " << line << endl;}}}return data;
}// 生成 MIDI 文件
void generateMIDI(const vector<double>& prices, const string& fcode) {MidiFile midiFile;midiFile.addTrack();midiFile.setTicksPerQuarterNote(480);// PPQ 需与 addNoteOff 参数一致// 计算价格范围auto [minIt, maxIt] = minmax_element(prices.begin(), prices.end());double minPrice = *minIt;double maxPrice = *maxIt;double priceRange = maxPrice - minPrice;// 音符范围配置int minNote = 48; // C3int maxNote = 84; // C5if (maxPrice / minPrice < 84.0/48.0) {maxNote = static_cast<int>(50 * (maxPrice / minPrice));}if (maxNote % 2 != 0) maxNote++;// 添加音符事件int track = 0;int channel = 0;int velocity = 80;int timeCounter = 0;int PPQ = 480; // 音符持续时间为 1个四分音符（480 ticks）for (double price : prices) {int pitch = (priceRange < 0.001) ? (maxNote + minNote) / 2 : minNote + static_cast<int>((price - minPrice) / priceRange * (maxNote - minNote));midiFile.addNoteOn(track, timeCounter, channel, pitch, velocity);midiFile.addNoteOff(track, timeCounter + PPQ, channel, pitch);timeCounter += PPQ; // ms 间隔1拍, 单位：毫秒 }// 保存文件string outputFile = "melo_" + fcode + ".mid";midiFile.write(outputFile);cout << "生成成功: " << outputFile << endl;
}int main(int argc, char** argv) {if (argc != 2 || strlen(argv[1]) != 6) {cerr << "用法: " << argv[0] << " <6位基金代码>" << endl;return 1;}string fcode = argv[1];string csvFile = "/funds/data/" + fcode + ".csv";try {auto data = readCSV(csvFile);if (data.size() < 20) {cerr << "数据不足: " << data.size() << " < 20" << endl;return 2;}vector<double> prices;for (auto& entry : data) {prices.push_back(entry.jz);}generateMIDI(prices, fcode);} catch (const exception& e) {cerr << "错误: " << e.what() << endl;return 3;}return 0;
}

3.修改后的 CMakeLists.txt 关键部分

# 在 "Programs:" 部分添加你的可执行文件（大约第 66 行附近）
if(NOT BUILD_MIDILIBRARY_ONLY)# 已有的工具列表...add_executable(textmidi tools/textmidi.cpp)add_executable(toascii tools/toascii.cpp)add_executable(tobin tools/tobin.cpp)# 添加你的自定义程序add_executable(fund2mid tools/fund2mid.cpp)  # 新增行# 继续原有工具列表...add_executable(tobinary tools/tobinary.cpp)add_executable(todec tools/todec.cpp)# ...# 在链接库部分添加（大约第 136 行附近）target_link_libraries(textmidi midifile)target_link_libraries(toascii midifile)target_link_libraries(tobin midifile)target_link_libraries(fund2mid midifile)  # 新增行target_link_libraries(tobinary midifile)target_link_libraries(todec midifile)

4.完整修改说明

文件结构要求：

midifile/
├── CMakeLists.txt
├── include/
├── src/
└── tools/├── fund2mid.cpp      # 你的程序源码├── createmidifile.cpp└── ...其他工具源码

必要修改点：

在 add_executable 列表中添加：
add_executable(fund2mid tools/fund2mid.cpp)
在 target_link_libraries 部分添加：
target_link_libraries(fund2mid midifile)

编译验证：

# 生成构建系统
mkdir build
cd build
cmake ..# 编译项目（Windows）
cmake --build . --config Release

适配注意事项

C++ 标准要求：
# 建议升级到 C++17（修改第 4 行）
set(CMAKE_CXX_STANDARD 17)
附件：完整的 CMakeLists.txt
