Installation on other distributions
I tried installing Looking Glass (Official Releases B2) in a fresh Arch (5.8.14-arch1-1 #1 SMP PREEMPT Wed, 07 Oct 2020) and it would give me error when I ran "cmake ../" that "Package 'glu', required by 'virtual:world', not found". I fixed it by installing package glu running pacman -S glu.
