glew fails to build from source on armhf

[Matthias Klose]

trying to build openimageio on armhf, ignoring the b-d on opencolorio, you get a build failure:

In file included from /usr/include/qt4/QtOpenGL/QGLWidget:1:0,

how ready is openimageio for OpenGLES?

[Nigel Stewart (nigels)]

GLEW does not support OpenGLES. Therefore it seems doubtful that openimageio-1.3.12 supports OpenGLES unless there is some kind of build option for that.

the current version builds fine, https://launchpad.net/ubuntu/+source/glew/1.13.0-2
