I am unable to fully test this locally as I do not have a CUDA-enabled
device. I can configure the project and compile, but at runtime I get errors
like:
```sh
/usr/bin/ld: src/arrow/gpu/libarrow-cuda.so.p/cuda_context.cc.o: in function
`arrow::cuda::CudaDevice::AllocateHostBuffer(long)':
/home/willayd/clones/arrow/cpp/builddir/../src/arrow/gpu/cuda_context.cc:266:(.text+0xa88):
undefined reference to `cuMemHostAlloc'
/usr/bin/ld: src/arrow/gpu/libarrow-cuda.so.p/cuda_context.cc.o: in function
`arrow::cuda::CudaDevice::MakeStream(unsigned
int)::{lambda(void*)#1}::operator()(void*) const':
/home/willayd/clones/arrow/cpp/builddir/../src/arrow/gpu/cuda_context.cc:286:(.text+0xc29):
undefined reference to `cuStreamDestroy_v2'
/usr/bin/ld: src/arrow/gpu/libarrow-cuda.so.p/cuda_context.cc.o: in function

/home/willayd/clones/arrow/cpp/builddir/../src/arrow/gpu/cuda_context.cc:280:(.text+0xf1f):
undefined reference to `cuStreamCreate'
```
I believe those missing symbols are from drivers that I cannot install,
although my familiarity with building CUDA applications is admittedly low
