Installs libmumbleoverlay.so in /app/utils/MumbleOverlay/lib/i386-linux-gnu/ (for 32bit games) and /app/utils/MumbleOverlay/lib/x86_64-linux-gnu/ (for 64bit games).
A game, in order to display the overlay, needs to be launched with the library preloaded. The game's launch options should thus be set to: LD_PRELOAD=/app/utils/MumbleOverlay/\$LIB/mumble/libmumbleoverlay.so %command%.
LD_PRELOAD=/app/utils/MumbleOverlay/\$LIB/libmumbleoverlay.so:/usr/\$LIB/libGL.so.1 %command% if the game is not linked against OpenGL library.
This extension is not officially published, yet. The following PRs still need to be discussed & merged:
- move Mumble Socket and Overlay to
$XDG_RUNTIME_DIR/mumble/: mumble-voip/mumble#5961 - build overlay on Linux and FreeBSD without client flag: mumble-voip/mumble#5967
- add Mumble overlay support: flathub/com.valvesoftware.Steam#1008
