Revert commit 887f3a88a6 (Intel: Add Intel DPC++ compiler
identification, 2020-09-21, v3.19.0-rc1~124^2). The compiler has
already been released, and is more usable with CMake by pretending to be
upstream Clang than by identifying it as a compiler for which we have
not implemented support.

NVCC's default architecture may be newer than the one supported by the
machine's GPU.
In such cases it's useful to have an environment variable for initializing
CMAKE_CUDA_ARCHITECTURES to avoid specifying it for every invocation.
Each source compilation generates a dependencies file. These dependencies
files are consolidated in one file per target. This consolidation is done
as part of command 'cmake -E cmake_depends` launched before evaluation of
makefile dependency graph.
The consolidation uses the same approach as `CMake` dependencies management.
Fixes: #21321
Many environment variables were documented late and got
assigned wrong versions by the script.
(The whole Help/envvar section was only added in 3.10).

4dca078829 Android: Link c++abi and android_support when necessary
738caa4d48 Android: Add options to control exceptions/rtti
Acked-by: Kitware Robot <kwrobot@kitware.com>
Merge-request: !5444
With the NDK's `android.toolchain.cmake`, the user can control whether
exceptions/rtti is enabled using `ANDROID_CPP_FEATURES`:
43b2de34ef/build/cmake/android.toolchain.cmake (548)
Add `CMAKE_ANDROID_RTTI` and `CMAKE_ANDROID_EXCEPTIONS` to support that.
The value of CMAKE_BUILD_TYPE is case insensitive. Furthermore, the
actual value of the variable will have the same casing as the user
specifies on the command line.
Extend the `-T <toolset>` option to support a `buildsystem=` field with
the Xcode generator. Add a `CMAKE_XCODE_BUILD_SYSTEM` variable to
inform project code about the selected build system variant.
Adds PCH_INSTANTIATE_TEMPLATES target property for enabling template
instantiation in precompiled headers.
Enabled by default. Currently only supported for Clang 11 and newer.
Implements #21133.

Only generate a graph dependency between a custom command and
a target when the custom command queries for the file path
of an artifact of the target.
This makes generator expressions such as `TARGET_FILE_DIR`
behave the same way as `TARGET_PROPERTY` which never generated
a graph dependency.

OBJECT and STATIC libraries (framework or non-framework) do not use
this build phase. Not all items to be linked use this build phase either.

Since commit 83ddc4d289 (VS: Do not select a Windows SDK too high for
current VS version, 2017-08-07, v3.13.0-rc1~72^2~2) we enforce a maximum
SDK version for the VS 2015 generator. The blog post linked in the
original commit is no longer available, but it can be seen here:
* https://web.archive.org/web/20190108032520/https://blogs.msdn.microsoft.com/chuckw/2018/10/02/windows-10-october-2018-update/
In particular, it states:
> VS 2015 Users: The Windows 10 SDK (15063, 16299, 17134, 17763)
> is officially only supported for VS 2017.
However, in some circumstances a higher version can be used.
Add a `CMAKE_VS_WINDOWS_TARGET_PLATFORM_VERSION_MAXIMUM` to override the
generator's default maximum SDK version.
Fixes: #20633
Add an `OPTIMIZE_DEPENDENCIES` target property and supporting
`CMAKE_OPTIMIZE_DEPENDENCIES` variable to optionally enable pruning and
flattening of outgoing dependencies from static libraries. Since they
do not actually link, they only depend on side effects of their
dependencies. Therefore we can drop dependencies that contribute no
side effects.
Change the default value of `CMAKE_AUTOMOC_PATH_PREFIX` to `OFF` to
restore compatibility with behavior of CMake 3.15 and below.
C++ source files that are generated by Qt's meta object compiler (moc)
include the header file that was passed as input argument to moc. This
is usually a path relative to the source directory, for example
#include "../../source/dir/myobject.h"
That is problematic for reproducible builds as described in #18815.
To cope with that, the target property AUTOMOC_PATH_PREFIX was
introduced in CMake 3.16 by commit d018d27c10 (Autogen: Add moc path
prefix generation (AUTOMOC_PATH_PREFIX), 2019-09-13, v3.16.0-rc1~94^2~4).
The property is default-initialized from the variable
`CMAKE_AUTOMOC_PATH_PREFIX`, which defaults to `ON`.
If this property is ON, and myobject.h is located in an include
directory of the target, moc-generated C++ files include the file
without the "path prefix":
#include "myobject.h"
This behavior, however, can break projects that have equally named
header files in different include directories. As "not breaking
existing projects" trumps "have reproducible builds by default" we
change the default of `CMAKE_AUTOMOC_PATH_PREFIX` to `OFF`.
Also, it is now possible to pass `-DCMAKE_AUTOMOC_PATH_PREFIX=ON` on the
CMake command line. Before, it was overridden in `CMakeGenericSystem`.
