345ba07f1d Add a CUDA test
test cuda: import fmt in CUDA source code

Current test is only for Windows(cl.exe).
Need to test more with the other host compilers...

* Activate the test when `find_package(CUDA)` worked
* The test runs with C++14

Detailed comments in 'test/cuda-test'

test cuda: add more comment / macro check

* checks both `__NVCC__` and `__CUDACC__`

More comments for CMake and CUDA source file.

test cuda: <fmt/core.h> checks NVCC and CUDA

The header file checks 2 things.

* __NVCC__: if the compiler is from NVIDIA
* __CUDACC__: if the source code is CUDA(.cu) file

Since we can't sure all users prefer latest, Version for
`find_pacakge(CUDA)` is downgraded to 9.0.
This is the minimum version for C++14 in CUDA
