[Bf-committers] Clang errors when compiling the Cycles CUDA kernel in Blender

[Sen Haerens]

The kernel compilation succeeded by adding "-ccbin=/usr/bin/llvm-gcc-4.2"
argument to nvcc and running manually.
Could this be specified somewhere in cmake?

It appears to be an issue in Mountain Lion (10.8.5).
