b7f0327dcd Tests: Cover macOS host architecture selection on Apple Silicon hosts
5f882f6ce5 macOS: Offer control over host architecture on Apple Silicon hosts
Acked-by: Kitware Robot <kwrobot@kitware.com>
Merge-request: !5589
Add test cases verifying that `CMAKE_APPLE_SILICON_PROCESSOR` set as
either a cache or environment variable causes that to be selected as the
host architecture. Also verify that sources compile using whatever is
selected as the host architecture, even when the explicit setting is not
used.
Issue: #21554
1. COMMAND_ERROR_IS_FATAL ANY will capture errors if the exit code is
non zero, there is a timeout or an abnormal exit.
2. COMMAND_ERROR_IS_FATAL LAST
will capture if only the last process has an exit code non zero, there
is a timeout or an abnormal exit.
Fixes: #21562
This change was originally made by commit 74b1c9fc8e (Explicitly specify
language flag when source LANGUAGE property is set, 2020-06-01,
v3.19.0-rc1~722^2), but it was reverted by commit 30aa715fac (Revert
"specify language flag when source LANGUAGE property is set",
2020-11-19) to restore compatibility with pre-3.19 behavior.
Implement the change again, but add policy CMP0119 to make this change
while preserving compatibility with existing projects.
Note that the `Compiler/{Clang,Intel,MSVC}-CXX` modules do not need to
specify `-TP` for their MSVC-like variants because we already use the
flag in `CMAKE_CXX_COMPILE_OBJECT`. Similarly for `Compiler/XL-CXX`
and `Platform/Windows-Embarcadero`.
Note also that this does not seem possible to implement for XL C.
Even with `-qsourcetype=c`, `xlc` complains about an unknown suffix:
`1501-218 (W) file /.../AltExtC.zzz contains an incorrect file suffix`.
It returns non-zero even with `-qsuppress=1501-218`.

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
This commit also prepares for embedding things other than
frameworks. In the future, we may want to embed resources and
other types supported by Xcode, so the target properties have
been documented in a way that clearly signals the future intent.
These are tests which shall assure that the upcoming changes regarding
the `GENERATED` source-file property and the associated new policy
CMP0118 do not change (or only slightly change) the current, observable
behavior when policy CMP0118 is set to `OLD`.
The `/GR` flag has been on by default since MSVC cl 14.0 from VS 2005.
Remove it from the default flags to make it easier for projects to pass
`/GR-` themselves to turn it off.
Projects may be using string processing to replace `/GR` with another
flag, so we cannot simply drop it. Add a policy to drop it in a
compatible way.
Fixes: #21428
The ExternalProject module cannot be implemented in the Xcode "new build
system" without using CMP0114's NEW behavior. When configuring for that
build system, warn if the policy is not set to NEW and use NEW behavior
anyway.
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.
