[Aaron M. Ucko]

Source: openimageio
Version: 1.7.17~dfsg0-1+b1
Severity: serious
Tags: upstream
Justification: fails to build from source (but built successfully in the past)
User: debian-arm at lists.debian.org
Usertags: armel armhf

Builds of openimageio on armel and armhf have been failing since the
switch to Qt 5 with a cascade of errors starting with

Could you please take a look?  I suspect you'll need to use GLES here
for consistency with Qt 5.
