Design decisions

To stay close to the design of Raylib. A concise yet powerful subset of OpenXR is exposed. Most of the API is there to wrap the interaction with Raylib (Mostly rendering). And covering very common usage, eg Head/Hands position.

Minimum Raylib version

Raylib 4.2

CMake options

RlOpenXR uses CMake (minimum 3.15) as it's build system.

Using the rlOpenXR as a dependency

Out of the box rlOpenXR only supports CMake. There are a few options on how to add a library as a dependency in CMake:

Subdirectory

Download the source for rlOpenXR into a subfolder in your project, for example: "third_party/rlOpenXR".

This can be done via git: git clone https://github.com/FireFlyForLife/rlOpenXR.git.

Or by manually going to the github repo and going to "Code" -> "Download Zip".

Then in your CMakeLists.txt file for your project, add the following lines:

add_subdirectory(third_party/rlOpenXR)

# ...

target_link_libraries(YourProject PUBLIC rlOpenXR) # Add rlOpenXR as a dependency to your project

FetchContent

In your CMakeLists.txt file, add the following lines:

FetchContent_Declare(
    rlOpenXR
    GIT_REPOSITORY https://github.com/FireFlyForLife/rlOpenXR.git
    GIT_TAG "v1.1.0"
)

FetchContent_MakeAvailable(rlOpenXR)

# ...

target_link_libraries(YourProject PUBLIC rlOpenXR) # Add rlOpenXR as a dependency to your project

In the FetchContent_MakeAvailable() call, CMake will download the repository via Git, and add it parse it's CMake file.
