The CUDA compiler automatic deprecation warnings are pure noise when
doing device linking, and should be suppressed to reduce the amount of
confusion from users.
Fix the default values of `CMAKE_CUDA_FLAGS[_<CONFIG>]` on Windows to
make the host compiler flags match those produced for C++ by the
`Platform/Windows-MSVC` module. This makes the flags consistent with
those used for C++.
On Windows with MSVC-like host compilers we must honor the standard
libraries chosen by the `Platform/Windows-MSVC` module. Otherwise C
code linked into the CUDA binary that expects to have these libraries
available may not link.
Previously we had a two issues when building cuda executables
that required separable compilation. The first was that we didn't
propagate FLAGS causing any -arch / -gencode flags to be dropped, and
secondly generators such as ninja would use the CXX language flags
instead of CUDA when the executable was mixed language.
Port Windows-specific compilation and linking rules over from the
`Platform/Windows-MSVC` module and adapt it for NVIDIA CUDA. On Windows
nvcc and its host compiler (MSVC) do not understand or use options like
`-fPIC` or `-std=`, so condition those out.
