[Beignet] cl_khr_gl_sharing stopped working

[Orm Finnendahl]

Hi Benson,

 thanks for the quick reply. Yes I have (and tried it
before). Unfortunately the intel-compute-runtime never reported the
cl_khr_gl_sharing extension, although the processor clearly should
support this (and it worked flawlessly on two laptops in the last
years using the beignet driver).

If beignet is deprecated and seizes to work: It is absolutely vital
for my work to have gl-sharing (and quite devastating news): Does
anybody know of a way to get this working on intel gpus?
