OpenVR SDK
---
OpenVR is an API and runtime that allows access to VR hardware from multiple
vendors without requiring that applications have specific knowledge of the
hardware they are targeting. This repository is an SDK that contains the API
and samples. The runtime is under SteamVR in Tools on Steam.
### Documentation
Documentation for the API is available on the [GitHub Wiki](https://github.com/ValveSoftware/openvr/wiki/API-Documentation)
More information on OpenVR and SteamVR can be found on http://steamvr.com

This is the source code for the OpenVR API client binding library which connects
OpenVR applications to the SteamVR runtime, taking into account the version
of the OpenVR interface they were compiled against.
The client binding library - openvr_api.dll on Windows, openvr_api.so on
Linux, and openvr_api.dylib or OpenVR.framework on macOS - knows how to find
and read the SteamVR runtime installation information which allows it to
find and dynamically connect to the installed runtime. In combination with the
interface version identifiers from /include/openvr.h which are baked
into applications at the time they are built, the OpenVR API client
binding library captures and conveys to the SteamVR runtime the version
of the OpenVR API interface behavior that the application expects.
Applications carry with them a private/local copy of the client binding
library when they ship, and they should install it locally to their
application. Applications should not install the client binding library
globally or attempt to link to a globally installed client binding library.
Doing so negates at least part of the ability for the client binding library
to accurately reflect the version of the OpenVR API that the application
was built against, and so hinders compatibility support in the face of
API changes.
Most applications should simply link to and redistribute with their application
the pre-built client binding library found in the /bin directory of this
repository. Some small number of applications which have specific requirements
around redistributing only binaries they build themselves should build
the client library from this source and either statically link it into
their application or redistribute the binary they build.
This is a cmake project, to build it use the version of cmake appropriate
for your platform. For example, to build on a POSIX system simply perform
cd src; mkdir _build; cd _build; cmake ..; make
and you will end up with the static library /src/bin/<arch>/libopenvr_api.a
To build a shared library, pass -DBUILD_SHARED=1 to cmake.
To build as a framework on apple platforms, pass -DBUILD_FRAMEWORK=1 to cmake.
To see a complete list of configurable build options, use `cmake -LAH`
