>Subject: [PATCH] glx: Refactor the configure options for glx implementation
> choice
>
>Instead of cascading support for various different implementations of
>GLX, all three options are now specified through the --enable-glx
>option:
>
>  --enable-glx=dri          : Enable the DRI-based GLX
>  --enable-glx=xlib         : Enable the classic Xlib-based GLX
>  --enable-glx=gallium-xlib : Enable the gallium Xlib-based GLX
>  --enable-glx[=yes]        : Defaults to dri if DRI is enabled, else
>                              gallium-xlib if gallium is enabled, else
>                              xlib
>
>This removes the --enable-xlib-glx option and fixes a bug in which both
>the classic xlib-glx and gallium xlib-glx implementations were getting
>built causing different versioned and conflicting libGL libraries to be
>installed.
