Apply the optimization from commit v3.10.0-rc1~131^2 (MSVC: Avoid
unnecessary C++ feature detection steps, 2017-09-11) to the case of
Clang simulating a version of MSVC that does not define standards.
Issue: #17274
Fix component include/library path if multiple versions are installed.
When searching for individual components, look only in the locations
we expect to find them that we already computed.
VS 15.3 has more features than we recorded in commit v3.7.0-rc1~156^2~2
(Features: Record features for VS 15 Preview 4, 2016-09-05).
While at it, update comments and simplify some cases.
If runtests('$unittest_file') throws an exception it is ignored. It is
easy to produce such an exception by passing a nonexistent file as
UNITTEST_FILE.
We already handle exceptions if the option NO_UNITTEST_FRAMEWORK is set.
Use the same method to handle exceptions thrown by runtests or by a
custom_Matlab_test_command.
Fixes#16660.
When `CMAKE_C_COMPILER` is `clcache`, pass plain `cl` as the host
compiler to `nvcc`. Otherwise, `nvcc` does not accept it.

This reverts commit v3.11.0-rc1~108^2 (CheckIncludeFiles: Honor
CMAKE_REQUIRED_LIBRARIES, 2017-12-24). The behavior change can
affect checks in existing projects that don't expect the behavior.
Introducing the behavior again will require a policy.
Fixes: #17874
Issue: #9514
The check for `wxWidgets_LIBRARIES` variable, introduced by e8b77084, fails
with the `wx-config` script generated by an MSYS build, because
`wxWidgets_LIBRARY_DIRS` is in POSIX style.
This commit fixes the problem with `wxWidgets_LIBRARY_DIRS` by converting it to
Windows style. The actual code were copied from bf643286, which does the same
thing for `wxWidgets_INCLUDE_DIRS`.
This allows defining compat versions of some C/C++ features with the name of the
keyword itself, so all code can look as if it was written for the new language
standard.
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 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
In some environments, libraries containing device code are installed in
directories searched by the host linker but not passed by nvcc to
nvlink. Make these libraries available by explicitly passing the
host linker search directories during device linking.
