# Build And Platform Inventory

Status: live
Last updated: 2026-05-31

This inventory records the known build surfaces during the CMake migration.
Keep it updated as platform paths move to shared CMake targets.

## Existing Build Entrypoints

| Platform/Target | Current Entrypoint | Notes |
| --- | --- | --- |
| Windows desktop | Root `CMakeLists.txt`, preset `windows-msvc-default`; target preset `windows-vs2026-x64` retained for VS 2026 | Raw `.sln/.vcxproj` files removed on 2026-05-31; local machine currently uses Visual Studio 17 2022 |
| Windows AppX | `PanoPainterPackage/Package.appxmanifest`, `.wapproj` referenced by solution | Distribution packaging |
| macOS | `PanoPainter-OSX/` project files and `Info.plist` | Uses `NSOpenGLView` today |
| iOS | `PanoPainter/Info.plist`, related Apple sources | Uses OpenGL ES today |
| Android standard | `android/android/build.gradle`, `android/android/CMakeLists.txt` | Native library target `native-lib` |
| Android Quest | `android/quest/build.gradle`, `android/quest/CMakeLists.txt` | OVR SDK imported libraries |
| Android Focus/Wave | `android/focus/build.gradle`, `android/focus/CMakeLists.txt` | Wave SDK imported libraries |
| Linux | `linux/CMakeLists.txt` | Old CMake 3.4, C++14 flag |
| WebGL/Emscripten | `webgl/CMakeLists.txt` | Old CMake 3.4, WebGL2 flags |

## Existing Version Generation

- Script: `scripts/pre-build.py`
- Output: `src/version.gen.h`
- Current behavior: derives version from git branch, latest tag, short hash,
  commit count, and configuration argument.
- Migration requirement: root CMake should call this script through a custom
  command and avoid unnecessary tracked-file churn where possible.

## Existing Dependency Sources

Hybrid policy: migrate reliable packages to vcpkg and retain SDK/patched
dependencies until each platform triplet is proven.

| Dependency | Current Source | Initial Policy |
| --- | --- | --- |
| fmt | `libs/fmt` | Move to vcpkg |
| GLM | `libs/glm` | Move to vcpkg |
| tinyxml2 | `libs/tinyxml2` | Move to vcpkg |
| stb | `libs/stb` | Move to vcpkg or interface target if package friction |
| CURL | `libs/curl-win`, `libs/curl-android-ios` | Move to vcpkg where triplets work |
| SQLite | `libs/sqlite3` | Move to vcpkg |
| GLAD | `libs/glad` | Move to vcpkg or generated backend target |
| Catch2 | none yet | Add through vcpkg |
| OpenVR | `libs/openvr` | Retain initially |
| OVR Platform/Mobile | `libs/ovr_platform`, `libs/ovr_mobile` | Retain initially |
| Wave SDK | `libs/wave_sdk` | Retain initially |
| Wacom WinTab | `libs/wacom` | Retain initially |
| AppCenter Apple | `libs/appcenter-apple` | Retain initially |
| openh264/mp4v2/libyuv | `libs/openh264`, `libs/mp4v2`, `libs/libyuv` | Retain initially |
| jpeg helpers | `libs/jpeg` | Evaluate after image tests exist |
| poly2tri/nanort/base64/hash-library | `libs/*` | Evaluate after component split |

## Current Validation Commands

These commands are the current local baseline.

```powershell
cmake --preset windows-msvc-default
cmake --build --preset windows-msvc-default --config Debug --target PanoPainter
ctest --preset desktop-fast --build-config Debug
powershell -ExecutionPolicy Bypass -File scripts\automation\test.ps1 -Preset desktop-fast -Configuration Debug
powershell -ExecutionPolicy Bypass -File scripts\automation\build.ps1 -Preset windows-msvc-default -Configuration Debug -Target pano_cli
cmake --preset android-arm64
powershell -ExecutionPolicy Bypass -File scripts\automation\platform-build.ps1 -Presets android-arm64
```

Known local toolchain state:

- CMake: 4.0.0-rc4
- Local Visual Studio generator selected by CMake: Visual Studio 17 2022
- Android SDK: `C:\Users\omara\AppData\Local\Android\Sdk`
- Android NDK: `C:\Users\omara\AppData\Local\Android\Sdk\ndk\29.0.14206865`
- Android arm64 headless configure/build passes through root CMake and the
  `platform-build` automation wrapper for `pp_foundation`, `pp_assets`,
  `pano_cli`, and their current headless test binaries.
- `vcpkg` is not on PATH yet; see DEBT-0007.

Known warnings after the current CMake app build:

- Legacy code/vendor warnings under `/W4`.
- Visual Studio vcpkg manifest warning because manifest mode is not enabled.
- `LNK4099` missing `yuv.pdb` for retained libyuv binaries.
- `LNK4098` runtime library conflict from retained vendor binaries.

Platform-specific commands should be added here when verified locally.
