# Build ft-screens in the dev container on the Frame (screens/build/ft-screens).
# compositor.c is the wlroots side (C; wlroots headers aren't C++), vr.cpp the OpenVR side.
# vr.cpp needs OpenVR's IVRIPCResourceManagerClient (ImportDmabuf), which the header
# shipped with SteamVR on the Frame predates, so the build uses the public header from
# Valve's openvr repo (pinned; the Frame's runtime supports its interface versions).
