# We don't have a wrapper which can supply obs-studio plugins so you have to
# somewhat manually install this:

# nix-env -f . -iA obs-wlrobs
# mkdir -p ~/.config/obs-studio/plugins/wlrobs/bin/64bit
# ln -s ~/.nix-profile/share/obs/obs-plugins/wlrobs/bin/64bit/libwlrobs.so ~/.config/obs-studio/plugins/wlrobs/bin/64bit
