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
