The new target property `EXPORT_COMPILE_COMMANDS` associated with the
existing global variable can be used to optionally configure targets for
their compile commands to be exported.
Fixes: #19462
The target property `ISPC_HEADER_SUFFIX` and associated global
variable now can control the suffix used when generating the
C/C++ interoperability ISPC headers.
In addition the default suffix is now "_ispc.h" which matches the
common convention that the ISPC compiler team uses and recommends.
b7f0327dcd Tests: Cover macOS host architecture selection on Apple Silicon hosts
5f882f6ce5 macOS: Offer control over host architecture on Apple Silicon hosts

Merge-request: !5589
Since commit b6c60f14b6 (macOS: Default to arm64 architecture on Apple
Silicon hosts, 2020-09-28, v3.19.0-rc1~63^2) we use `sysctl` to detect
that we are running on Apple Silicon in a way that pierces Rosetta.
This always sets `CMAKE_HOST_SYSTEM_PROCESSOR` to be `arm64` on such
hosts. However, macOS offers strong support for running processes under
an emulated `x86_64` architecture.
Teach CMake to select either `arm64` or `x86_64` as the host
architecture on Apple Silicon based on the architecture of its own
process. When CMake is built as a universal binary, macOS will select
whichever slice (architecture) is appropriate under the user's shell,
and `CMAKE_HOST_SYSTEM_PROCESSOR` will match.
Also offer a `CMAKE_APPLE_SILICON_PROCESSOR` variable and environment
variable to provide users with explicit control over the host
architecture selection regardless of CMake's own architecture.
Finally, if `CMAKE_OSX_ARCHITECTURES` is not set, pass explicit flags to
the toolchain to use selected host architecture instead of letting the
toolchain pick.

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.
