This directory contains all project dependencies, organized by type.

The deps/third_party/CMakeLists.txt centrally manages all third-party dependencies using CMake FetchContent:

1. OpenXR SDK: Automatically fetched and built as a static library
2. yaml-cpp: Automatically fetched and built as a static library
3. pybind11: Fetched only when BUILD_PYTHON_BINDINGS=ON (header-only)
   • Makes pybind11::module target available to all Python binding modules

Dependencies are automatically downloaded during CMake configuration. No manual initialization is required.

This centralized approach prevents duplicate includes and ensures consistent configuration across all modules.

The cloudxr/ folder contains files and configurations for deploying the NVIDIA CloudXR, it uses Docker Compose to setup the entire system with 3 different containers:

1. CloudXR runtime
2. Web server that hosts the CloudXR Web XR app
3. WebSocket SSL proxy

When adding new third-party dependencies:

To add a new third-party dependency:

1. Update CMakeLists.txt in this directory to add a FetchContent declaration:

   FetchContent_Declare(
       <name>
       GIT_REPOSITORY <repository-url>
       GIT_TAG        <commit-sha-or-tag>
   )
   FetchContent_MakeAvailable(<name>)

2. Document it in this README with purpose, license, version, and repository information

3. If you need to preserve a specific version, use the full commit SHA in GIT_TAG

4. Update the Build from Source doc with any new requirements
