# Build

## Prerequisites

- Windows 10 SDK **18362** or later
- Visual Studio 2022+ (or Build Tools) with **Desktop development with C++**
- [Ninja](https://ninja-build.org/) (optional; matches CI)

Install Ninja from [ninja-build.org](https://ninja-build.org/) or [GitHub releases](https://github.com/ninja-build/ninja/releases), or use `.\build.ps1 -Generator VisualStudio` (bundled with VS).

## Build commands

From the repo root:

```powershell
.\build.ps1                              # Release → build\wrec.exe
.\build.ps1 -Clean                       # clean rebuild
.\build.ps1 -Generator VisualStudio      # → build-vs\Release\wrec.exe
```

Default generator is **Ninja** + **Release**, same as CI.

## CI

GitHub Actions workflows under `.github/workflows/` build on push and produce release zips and Inno Setup installers (`wrec-v<version>-windows-amd64-installer.exe`). Release packaging requires [Inno Setup 6](https://jrsoftware.org/isinfo.php) (`ISCC.exe`). See `build.yml` and `release.yml` for details.
