# vcpkg Integration for Windows Builds

This document describes how to use vcpkg for Windows builds in Visual Studio with YAZE.

## Overview

vcpkg is Microsoft's C++ package manager that simplifies dependency management for Windows builds. YAZE now includes full vcpkg integration with manifest mode support for automatic dependency resolution.

## Features

- **Manifest Mode**: Dependencies are automatically managed via `vcpkg.json`
- **Visual Studio Integration**: Seamless integration with Visual Studio 2019+
- **CMake Presets**: Pre-configured build presets for Windows
- **Automatic Setup**: Setup scripts for easy vcpkg installation

## Quick Start

### 1. Setup vcpkg

Run the automated setup script:
```cmd
# Command Prompt
scripts\setup-vcpkg-windows.bat

# PowerShell
.\scripts\setup-vcpkg-windows.ps1
```

### 2. Build with vcpkg

Use the Windows presets in CMakePresets.json:

```cmd
# Debug build
cmake --preset windows-debug
cmake --build build --preset windows-debug

# Release build
cmake --preset windows-release
cmake --build build --preset windows-release
```

## Configuration Details

### vcpkg.json Manifest

The `vcpkg.json` file defines all dependencies:

```json
{
  "name": "yaze",
  "version": "0.3.1",
  "dependencies": [
    "zlib",
    "libpng", 
    "sdl2",
    "abseil",
    "gtest"
  ]
}
```

### CMake Configuration

vcpkg integration is handled in several files:

- **CMakeLists.txt**: Automatic toolchain detection
- **cmake/vcpkg.cmake**: vcpkg-specific settings
- **CMakePresets.json**: Windows build presets

### Build Presets

Available Windows presets:

- `windows-debug`: Debug build with vcpkg
- `windows-release`: Release build with vcpkg

## Dependencies

vcpkg automatically installs these dependencies:

- **zlib**: Compression library
- **libpng**: PNG image support
- **sdl2**: Graphics and input handling
- **abseil**: Google's C++ common libraries
- **gtest**: Google Test framework (with gmock)

## Environment Variables

Set `VCPKG_ROOT` to point to your vcpkg installation:

```cmd
set VCPKG_ROOT=C:\path\to\vcpkg
```

## Troubleshooting

### Common Issues

1. **vcpkg not found**: Ensure `VCPKG_ROOT` is set or vcpkg is in the project directory
2. **Dependencies not installing**: Check internet connection and vcpkg bootstrap
3. **Visual Studio integration**: Run `vcpkg integrate install` from vcpkg directory

### Manual Setup

If automated setup fails:

```cmd
git clone https://github.com/Microsoft/vcpkg.git
cd vcpkg
.\bootstrap-vcpkg.bat
.\vcpkg.exe integrate install
```

## Benefits

- **Consistent Dependencies**: Same versions across development environments
- **Easy Updates**: Update dependencies via vcpkg.json
- **CI/CD Friendly**: Reproducible builds
- **Visual Studio Integration**: Native IntelliSense support
- **No Manual Downloads**: Automatic dependency resolution

## Advanced Usage

### Custom Triplets

Override the default x64-windows triplet:

```cmd
cmake --preset windows-debug -DVCPKG_TARGET_TRIPLET=x86-windows
```

### Static Linking

For static builds, modify `cmake/vcpkg.cmake`:

```cmake
set(VCPKG_LIBRARY_LINKAGE static)
set(VCPKG_CRT_LINKAGE static)
```
