Remember two fundamental things regarding GPL:

1) you yourself can do whatever you want with the code (including linking with 
GPL-incompatible code) as long as you do not distribute the binary;
2) distribution of a binary inside a company, including between various company 
sites, is not distribution from the point of view of GPL.

However, you can't send such a hybrid (GPL + non-GPL) code to another company.

So, if you want/need GPU acceleration, just do it - taking into account the 
above limitations.


By the way, a very well known 'ffmpeg' _explicitly_ allows to build a GPL + 
non-GPL version - with the warning reminding you you can't distribute it. I 
mean, its 'configure' script allows it.
