Installing the VirtualGL Client on Windows (Cygwin)

[Deepa]

I am trying to install VirtialGL through Cygwin.

I ran into the following

Problem 1/1
nothing provides libGLU1 needed by VirtualGL-2.6.3-20191024
Solution 1/1 (default)
  - do not ask to install VirtualGL-2.6.3-20191024

I am not able to find libGLU1 even if I try to install libGLU1 prior to installing VirtualGL.

Any suggestions on how to install libGLU1 in cygwin will be of great help!

<sigh>  Supporting Cygwin is a pain in the @$$ these days.  The right way to go about that would be for someone to build and maintain an official Cygwin package for VirtualGL, but I don't personally have time to do that-- particularly given that the VirtualGL Client is more or less a legacy feature at this point (most people these days use VirtualGL with an X proxy, such as TurboVNC, because it requires a lot less client-side software.)  Cygwin unfortunately doesn't make it easy for open source developers to release their own packages independently of the Cygwin deployment infrastructure.  I tried various ways of doing that and ultimately had to settle upon a hack:

https://github.com/VirtualGL/vglcygsetup

The problem with this hack, though, is that it downloads the VirtualGL package into a local directory and installs it from there, so unfortunately the dependencies won't be automatically satisfied.  The easiest way around that is to install libGLU1 and any other dependent packages (libGL1, libX11_6, libXext6, libturbojpeg0, libXtxt6) prior to running vglcygsetup.
