Mechanism to specify openvr_api library location
Defined in <SDL3/SDL_hints.h>
#define SDL_HINT_OPENVR_LIBRARY "SDL_OPENVR_LIBRARY"
By default, when using the OpenVR driver, it will search for the API library in the current folder. But, if you wish to use a system API you can specify that by using this hint. This should be the full or relative path to a .dll on Windows or .so on Linux.
This hint is available since SDL 3.2.0.
