Subject: bug#64981: GTK4 applications broken (missing libGLESv2)

Hi everyone,

Not sure if people saw this patch, has anyone tested if it fixes the
problem for them? I can include it in an upcoming mesa-updates branch
with other related updates/rebuilds.

<https://issues.guix.gnu.org/65375>

Hope I got everyone from the original bug thread (seems many replies
didn't go directly to everyone) and cc'ed the patch number as well.

Thanks!
John
