Android NDK r16b comes with
Android clang version 5.0.300080 (based on LLVM 5.0.300080)
Although it claims version 5, it does not support the `-std=c++17`
or `-std=c++2a` flags that upstream Clang does.
Android NDK r17-beta1 comes with
Android (4639204 based on r316199) clang version 6.0.1
that does have the flags.

This can be used for example to organize all following targets into one
Visual Studio folder:
set(CMAKE_FOLDER Libraries)
add_subdirectory(libA)
add_subdirectory(libB)
set(CMAKE_FOLDER Executables)
add_subdirectory(progA)
Another possibility is using the current directory name for all
following targets in subdirectories:
get_filename_component(dirname "${CMAKE_CURRENT_SOURCE_DIR}" NAME)
string(APPEND CMAKE_FOLDER "/${dirname}")
This is useful if, for example, you want ccache to be used
for nvcc. With the current behavior, cmake always picks up
/usr/local/cuda/bin/nvcc, even if there is a ccache nvcc
stub in the PATH. Allowing for CUDA_NVCC_EXECUTABLE lets
us work around the problem.

The MSVC C compiler has no notion of C language standards or flags.
Tell CMake to assume that all language standards are available.
Record available C language features depending on the version of
the compiler.
Fixes: #17858
Remove an unused variable and its containing local scope accidentally
left by commit v3.11.0-rc1~44^2 (Reduce allocation of temporary values
on heap, 2018-01-25).
Refactoring in commit v3.9.0-rc1~156^2 (c++: prefer vectors over lists,
2017-05-04) switched `cmCTestSVN::Repositories` from `std::list` to
`std::vector`. This can cause re-allocation when svn externals are
processed and break the `RootInfo` pointer that is supposed to point at
the first repository element. Switch back to `std::list` so that the
address remains stable.
Fixes: #17854
