#!/bin/bash

# 1. 检查并清理构建目录
if [ -d "build" ]; then
    echo "清理旧的构建目录..."
    rm -rf build
fi
mkdir build
cd build

# 2. 配置项目
# -A x64 指定生成 64 位程序
# 如果你安装了多个 VS 版本，建议显式指定 -G "Visual Studio 17 2022"
echo "正在使用 MSVC 配置项目..."
cmake .. -G "Visual Studio 17 2022" -A x64

# 3. 构建项目
# MSVC 是多配置生成器，所以必须指定 --config Release
echo "正在编译 (Release 模式)..."
cmake --build . --config Release -j8

# 4. (可选) 自动部署 Qt 依赖
# 注意：即使你用 MSVC 编译，也要用 MSVC 版本的 windeployqt
# C:/path/to/msvc_64/bin/windeployqt.exe ../bin/MyQtApp.exe

echo "构建完成！"
