There's a PR that was just merged that changes the CMake option OPENCOMPOSITE_SEARCH_PATH to OVR_COMPAT_SEARCH_PATH.
This allows xrizer to be used instead of opencomposite.
I maintain opencomposite-git and xrizer-git, and I was wondering if I should add provides=("openvr-compat") so you can be more generic in your dependencies?
I think that would let you do optdepends=("openvr-compat: ..."), but I'm not 100% sure since I've never done that with AUR packages.
