In commit bb61c2d024 (Clang: use -imsvc for system include dirs when
running on Windows, 2020-09-16, v3.19.0-rc1~162^2) we added `-imsvc`
for all Clang compilers targeting the MSVC ABI. However, the option
only exists for the MSVC-like front-end. The GNU-like front-ends
use `-isystem`.

Xcode 12 doesn't allow nested builds within the same build directory.
That means we can no longer do an install by building the install target
when IOS_INSTALL_COMBINED is true. We can, however, still do an install
by running the cmake_install.cmake script or executing cmake --install,
since there is no outer build and therefore the associated SDK can be
built as a sub-build.
The non-build methods previously didn't work when
IOS_INSTALL_COMBINED was true because the generated install script
and the CMakeIOSInstallCombined script both made certain assumptions
that relied on being part of a build. Those assumptions are now
removed. A side-effect of this work is that cpack now also works from the
command line when IOS_INSTALL_COMBINED is true.

Update the list of known versions.
Run the command
cmake -DBOOST_DIR=/path/to/boost_1_75_0 \
-P Utilities/Scripts/BoostScanDeps.cmake
to extract dependencies from the 1.75.0 source tree.
They differ from 1.74's dependencies by the addition of
dependencies of the json component, so add a new version
block to FindBoost.

Refactoring in commit 7cc815a2a6 (CUDAToolkit: Detect CUDA SDK that
don't have nvcc, 2020-07-24, v3.19.0-rc1~366^2) accidentally broke
use of the `CUDA_PATH` environment variable.

The `-nofor_main` flag was originally added by commit ccdd3e943d (Fix
Intel Fortran SHARED libraries on Linux, 2009-10-27, v2.8.2~915). Since
then, Intel Fortran renamed the option to `-nofor-main` and deprecated
the old name. The new name has been available for a long time, so
we can just switch to it.

The execution of this tool can output error logs to the output during
configure. This can then be caught by CTest and flagged as an error
during the build.
Use `target_link_libraries` to set `INTERFACE_LINK_LIBRARIES` so that
the `debug` and `optimized` keywords work.
In commit a8e0a6b3e4 (FindHDF5: Port changes from VTK, 2020-06-10,
v3.19.0-rc1~312^2~1) we added use of `HDF5_LIBRARIES`, but the value may
contain `debug` and `optimized` keywords.

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.

Commit 951640f1f9 (FindPython: manage SOABI for all Python versions,
2020-08-11) extended support for Python2's SOABI variable in order to
support the PyPy interpreter as well. This caused a regression in the
way that the SOABI variable was built up for the CPython interpreter.
This caused the variable to be set to `.so` which ended up causing a
doubling of the resulting `SOABI` variable in the end.

When cross-compiling with Xcode our compiler id test binary may be
compiled with multiple architectures. The INFO strings should be
identical and therefore de-duplicated. However, this can be broken by
stray text that happens to sit immediately before or after an INFO
string. Filter out such text so we can match clean INFO strings.

Customer reported problems detecting the Cray compiler on their Apollo80
system. We were checking for the __CRAYXC and __CRAYXE predefined
macros. These macros reflect the platform that the compiler is running
on, i.e. Cray XC and Cray XE machines. Naturally, this didn't work on
Apollo80.
This commit uses the official Cray compiler identification macros which
are defined on every platform:
CCE Version C Macro C++ Macro Fortran Macro
============ ======== ========= =============
version < 9 _CRAYC _CRAYC _CRAYFTN
version >= 9 __cray__ __cray__ _CRAYFTN
Rename the `CheckPIESupported` helper functions so that they

way to check if a source compiles, 2020-09-14, v3.19.0-rc1~118^2~1), and
commit 357e2ef429 (CheckSoureRuns: Add a unified way to check if a
source runs, 2020-09-14, v3.19.0-rc1~118^2) to work when variables of
the language names are set.
Fixes: #21500
If the user specifies CMAKE_CUDA_ARCHITECTURES we use those during detection
and error out if they don't work.
For Visual Studio a dummy project file is used instead of invoking the compiler
directly. NVCC would thus use its default and we'd fail if
CMAKE_CUDA_ARCHITECTURES was anything other than NVCC's default.
Use the necessary project file variable in CMakeDetermineCompilerId.cmake to
match other generators.
Fixes#21492.
