When `CMAKE_OSX_ARCHITECTURES` is not specified, we add the Xcode
setting `ONLY_ACTIVE_ARCH = YES` with the intention of targeting the
native architecture of the host. However, the default `ARCHS` value
chosen by "Xcode 12 Universal Apps" includes multiple architectures.
Add an explicit `ARCHS` setting with value `$(NATIVE_ARCH_ACTUAL)`
to tell Xcode to use the host's native architecture only.

Since commit f034b0f663 (CMake compilation: do not use compiler
extensions, 2020-03-14, v3.18.0-rc1~494^2) we need to explicitly enable
availability of `strdup`.

Since commit 2026915f8f (Swift: Propagate Swift_MODULE_DIRECTORY as include
directory, 2020-02-03, v3.18.0-rc1~547^2) we internally call
`GetAllConfigCompileLanguages` on all directly linked targets without
checking if they are interface libraries that don't compile at all.
That violates an internal assumption and assertion.
Fixes: #20977
A user could specify the same directory scope to set_property()
multiple times, which in conjunction with APPEND would append the
property multiple times.
Make sure to deduplicate scopes across both DIRECTORY and
TARGET_DIRECTORY options, so that a property is only appended
once in such a scenario.

Starting on macOS 11, the dynamic loader has a builtin cache of
system-provided dylib files. They do not actually exist on the
filesystem. However, runtime dependencies recorded in Mach-O binaries
can still have `LC_LOAD_DYLIB` entries referring to such dylib files by
absolute path. The dynamic loader simply resolves the paths from its
cache. Teach `file(GET_RUNTIME_DEPENDENCIES)` to skip dependencies on
such dylib paths. For practical software distribution purposes they do
not exist, or at least can be assumed available on all deployments.
Issue: #20863
Allow to specify both DIRECTORY and TARGET_DIRECTORY at the same time in
`set_source_files_properties()` and `set_property(SOURCE)` commands.
Add test cases and update the documentation.

Fix code added by commit d7679f6427 (QCMakeCacheView: use non-deprecated
List and Set constructions, 2020-06-10, v3.18.0-rc2~13^2), used
conditionally on Qt 5.14 or above, to compile as C++14.
In commit dd8365b3f1 (Merge branch 'upstream-KWSys' into update-kwsys,
2020-04-06, v3.18.0-rc1~397^2) we imported KWSys commit `019afb6ea`
(SystemTools: Drop GetCurrentWorkingDirectory 'collapse' argument,
2020-04-03). That caused `GetCurrentWorkingDirectory` to no longer send
paths through the KWSys translation map and broke CMake's detection of
the absolute path to a build directory containing a symbolic link.
Add our own `cmSystemTools::GetCurrentWorkingDirectory` wrapper around
the KWSys method in order to restore that mapping.

The two options were concatenated internally for both ARCHIVE_CREATE
and ARCHIVE_EXTRACT. The distinction between files and dirs was not
meaningful. Therefore, replace them with PATHS or PATTERNS
to more accurately describe the way the options are used.

In commit a6fee09484 (file: Add CONFIGURE subcommand, 2020-03-06,
v3.18.0-rc1~584^2) we accidentally treated relative path outputs
with respect to the current working directory. Treat them with
respect to the current binary directory instead.

Refactoring in commit 6b85166920 (ENH: Refactor find_library search
logic, 2008-09-22, v2.8.0~1665) dropped a call to `FileExists` on the
path under the assumption that the presence of a file in a directory
listing means it exists. However, dropping that also dropped a check
that verifies the file is readable. Restore the `FileExists` call to
ensure that we only find readable libraries.
Since commit d74e651b78 (Makefiles: Re-implement makefile target path
escaping and quoting, 2020-04-10, v3.18.0-rc1~334^2~1), `WriteMakeRule`
now correctly escapes `$` in make target paths as `$$`. However, this
caused an existing call site to escape the `$(VERBOSE)` variable
reference in the `.SILENT` prefix, making it ineffective. Sub-makefiles
are invoked with `MAKESILENT`, so this bug matters only for the `all`
target, which emits progress messages from toplevel.
Before:
# Suppress display of executed commands.
$$(VERBOSE).SILENT:
After:
# Suppress display of executed commands.

The ability to disable adding architectures completely for packaging purposes
and cases requiring passing the architectures flags explicitly has been
requested.
Support a false value for CUDA_ARCHITECTURES and CMAKE_CUDA_ARCHITECTURES
for this purpose.

cc02ced530 find_program: Revert "Find programs that are executable but not readable"
Acked-by: Kitware Robot <kwrobot@kitware.com>
Merge-request: !4871
Clang isn't very good at finding the installed CUDA toolkit.
The upstream recommendation is that we should pass the toolkit explicitly.
Additionally:
* Avoids Clang having to search for the toolkit on every invocation.
* Allows the user to use a toolkit from a non-standard location by simply
setting CUDAToolkit_ROOT. The same way as with FindCUDAToolkit.
Clang wants the directory containing the device library and version.txt as the
toolkit path.
We thus pass the newly introduced CUDAToolkit_LIBRARY_ROOT as the toolkit path.
We save CUDAToolkit_ROOT_DIR and CUDAToolkit_LIBRARY_ROOT on Clang to have them
available in try_compile() and avoid unnecessary re-searching or a possibly
different installation being found in FindCUDAToolkit.
This however means that the selected toolkit can't be changed after the initial
language enablement.
We now determine CUDA compiler ID before doing actual detection, as we don't
want to spend time finding the CUDA toolkit for NVIDIA.
Implements #20754.
The fix in commit 86e6349ef7 (find_program: Find programs that are
executable but not readable, 2020-04-04, v3.18.0-rc1~372^2) can break
existing projects that were (likely accidentally) relying on the
old behavior to find files that are readable but not executable.
Revert the fix for now. We can re-introduce it with a policy later.
Instead of reverting the test case, update it to cover the old behavior.
That can serve as a reference for testing the policy when introduced.

C/C++ language flag to MSVC, 2020-05-15, v3.18.0-rc1~139^2~1) failed to
