Description younky.yang 2017-12-25 03:16:12 UTC

with 2.2.5, it just depends on virtual/opencl, why 2.4.0 depends on clang-4? I tried to build with clang-5, and there is no issue so far. 

So anyone can explain this?

^ that is wrong.
clang is *only* used for test-compiling opencl kernels during build time.
it does not and will not help during runtime.
you probably should just disable that kernel test-compilation via -DTESTBUILD_OPENCL_PROGRAMS:BOOL=OFF cmake flag.

Moved clang/llvm to DEPEND (build time only) and also allow to use version 5.
