the preferred GPU architecture directly included rather than having to wait
for the JIT compiler of the CUDA driver to translate it.
Version 8.0 or later of the CUDA toolkit is required and a GPU architecture
of Kepler or laters, which must *also* be supported by the CUDA toolkit in use
**and** the CUDA driver in use.
When building with CMake, you **must NOT** build the GPU library in ``lib/gpu``
using the traditional build procedure. CMake will detect files generated by that
process and will terminate with an error and a suggestion for how to remove them.
