no 32bit liblinuxtrack.so.0 for Controller.exe

Issue Description

I am unable to get headtracking in a Steam game (Project Cars 2). It is a Proton 64 bit game. It is not very clear to me, if I have to run the Controller.exe before the game as a forked process or not. Some forums suggest this. I am able to do this easily with SteamTinkerLaunch but with no luck.

That said I am trying to identify the problem and test the Controller.exe in this wine prefix first and encounter errors.

Steps to Reproduce

Download LinuxTrack X-IR v0.99.27
Run the AppImage
Execute prefix=/home/user/.steam/debian-installation/steamapps/compatdata/378860/pfx winetricks (the prefix path of the Steam Game (Proton) Project Cars 2)
In winetricks open an explorer to start drive_c/Program Files (x86)/Linuxtrack/Controller.exe

Expected Behavior

Program to set Hotkeys for Resume/Pause/Stop Tracking should be usable.

Actual Behavior

Error occurs: "Can't start linuxtrack!!!", the Hotkey definition program in the background closes after clicking "OK" on the alert.

The libraries of my own build and of the AppImage are found but not compatible with this 64bit prefix (as this is a 64bit game).
