VS 2017 toolsets now use this flag by default if `UseFullPaths` is
not explicitly set to `false` in the .vcxproj file. Since there is
no negative form of this flag there is no way for projects to turn
it off through our flag map. Also, the Makefile and Ninja generators
do not add this flag unless it is explicitly specified by the project.
Teach our generator to set `UseFullPaths` to `false` in VS 2017
unless the project or use has explicitly specified `/FC`.
Fixes: #18261
Explicitly turn off `ReferenceOutputAssembly` in `ProjectReference`
elements naming other project files whose types do not produce
assemblies. We already do this for `C#` but it makes sense for other
languages too.

When `*.cs` files are provided, do not generate a `<Link>` element in
the `.csproj` project if those files are descendants of
`CMAKE_CURRENT_BINARY_DIR`. This comparison happens for each file.
We already place all include directories for CUDA inside `CudaCompile`
so we do not need to use any from `ClCompile`. Tell `CudaCompile`
not to use the host compiler's include directory settings.
Fixes: #18101
This family enable to manage link flags
Three new properties:
* directory property: LINK_OPTIONS
* target properties: LINK_OPTIONS and INTERFACE_LINK_OPTIONS
Two new commands
* add_link_options(): to populate directory property
* target_link_options(): to populate target properties
Fixes: #16543
Run the `clang-format.bash` script to update all our C and C++ code to a
new style defined by `.clang-format`. Use `clang-format` version 6.0.

Add new `version=` parameter in the toolset setting to select the
version. Add variable `CMAKE_VS_PLATFORM_TOOLSET_VERSION` to hold the
version, if one is set (blank indicates default).

According to https://docs.nvidia.com/cuda/nvrtc/index.html there are
some cases where a CUDA binary "...must be linked against the CUDA
device runtime (cudadevrt) library". When `nvcc` drives linking it
automatically links to runtime libraries as follows:
* -cudart=none: None
* -cudart=shared: -lcudadevrt -lcudart
* -cudart=static: -lcudadevrt -lcudart_static
The `cudadevrt` library is the cuda device runtime library. It is
always static so passing it to the linker when not necessary does
not hurt anything.
With Ninja and Makefile generators, we detect `cudadevrt` and either
`cudart` or `cudart_static` libraries implied by `nvcc` and then add
them to link lines driven by a host compiler. However, this does not
work with the VS generator because the CUDA Toolkit Visual Studio
integration does not use `nvcc` to link binaries and instead uses
`link.exe` directly.
Visual Studio project files (`.vcxproj`) for CUDA are expected to
explicitly list the needed runtime libraries. Our VS generator already
adds `cudart.lib` or `cudart_static.lib` based on the `-cudart=` flag.
Update it to also add `cudadevrt.lib` as nvcc does.
Fixes: #17988
When generating a `ProjectReference` with `ReferenceOutputAssembly` set
to `false`, also set `CopyToOutputDirectory` to `Never`. Otherwise
MSBuild might report a diagnostic like
Project '<name>' is not up to date.
CopyLocal reference '...\ZERO_CHECK' is missing from output location.
and rebuild the referencing project unnecessarily.
Refactoring in commit 3f315dc128 (cmVisualStudio10TargetGenerator: XML
refactoring, 2018-05-02) accidentally left the `<Import>` element for
the CUDA build customizations unclosed.
