[Insight-users] itkGPUKernelManager compile error

[Denis Shamonin]

Hi Xiaoxiao,

I would like to do it. And I have a clear vision how to make the OpenCL
foundation for ITK4.

But in fact, to make it better would require much more work then just a
simple merging.
I have already some draft version of major improvements.
But I am pretty much occupied with my current projects and I have little
time and budget to work on it.

Regards,
-Denis Shamonin
