I added an apparently operational cuda auto-build (any .cu file placed in
src or src/internal should work). It seems to work fine but let me know if
it causes havoc.
Important note - the cuda build system hates the IMP namespace,
specifically. Perhaps its some internal cuda macro. It means we cannot
include <modulename>_config.h in any cuda files, for now, and need to add a
bypass if we need to access an IMP method or object from cuda code.
