<pre>I'm getting a compiler error when building miniQMC with OpenMP offload.
I succeeded in the compilation with CUDA8 but failed with CUDA9.2(V9.2.148). I
got the following compiler error.
In the intermediate step, /tmp/libopenblas-aee48e.cubin was not created
properly. I got a file with a zero size.
