[Bf-committers] State of Visual Studio 201X... Warning: may contain chaotic content ...

[Martijn Berger]

Hi Jürgen,

You can also use CUDA 5.0 with windows 7.1 SDK to build cubins and build
rest of blender with MSVC 2013.
The buildbot for MSVC 2013 already does this. I should add cmake support
for it and it is a work around but one that works very well and reliably
for me.

Best Regards,

Martijn
