Previously we added fallbacks to `llvm-{ar,strip}` on Apple hosts
in case of cross-compiling because the `APPLE` platform variable
was not set w.r.t. the target platform. The platform variable
has been fixed, so remove the fallbacks.
Issue: #23333
Set target platform identification variables like `APPLE` and `LINUX`
as soon as the target system is identified. This makes them available
during toolchain and binutils selection.
Fixes: #23333
Make `CMAKE_LIBRARY_ARCHITECTURE_REGEX` available while determining
compilers before `Platform/{kFreeBSD,GNU}` is loaded.
Follow up commit cc737ae829 (Linux: Provide multiarch library directory
regex earlier, 2023-05-31).
If `OpenACC_C_FLAGS` contains `-h acc`, the flag pair needs to
be preserved as a shell command fragment, and must not be split by
de-duplication with other `target_compile_options`.
Fixes: #24963
If `OpenMP_C_FLAGS` contains `-Xclang -fopenmp`, the flag pair needs to
be preserved as a shell command fragment, and must not be split by
de-duplication with other `target_compile_options`.
Fixes: #24966
Git config options can be passed to git clone before or after the
"clone" keyword. If specified before, the config setting is only
applied to that command invocation. It acts to override the value
in the global or project defaults (the latter doesn't exist for clone).
When the config setting is passed after the "clone" keyword, it is
saved into the cloned repository's config and will persist for later
git operations. The existing implementation expected the latter
behavior, but put the config setting before the "clone" keyword
and therefore the setting was not persisting to the git update
step. Move it to after the "clone" keyword so that it will persist.
The submodule handling is different. There is no support for
doing a "git submodule update" with a "sticky" config setting.
Instead, you have to pass the setting with all such calls. The
existing implementation was doing this for the clone step, but
not the git update step. Add the config setting there as well
so that submodules also effectively have the sslVerify setting
persist to the update step too.

We need `CMAKE_LIBRARY_ARCHITECTURE` to find the package before HIP
compiler ABI detection. However, if HIP is the first enabled language,
the value is not known until `CMAKE_HIP_LIBRARY_ARCHITECTURE` is
determined by the ABI detection step. Resolve this by detecting
`CMAKE_HIP_LIBRARY_ARCHITECTURE` from the compiler id output.
Fixes: #24562
Update the list of known versions.
There is a new header-only library, Boost.MySQL. It has no
dependencies and has a core header `<boost/mysql.hpp>`.
Run the command
cmake -DBOOST_DIR=/path/to/boost_1_82_0 \
-P Utilities/Scripts/BoostScanDeps.cmake
to extract dependencies from the 1.82.0 source tree.
They are the same as 1.81's dependencies, so just update
the version check for warning about newer versions.
The matching became too eager after commit 079ea66468
(CMakeDetermineCompilerABI: Handle NVCC-style -Werror flags, 2020-10-04,
v3.19.0-rc1~45^2). When -Werror was specified without a value we would
eat the following flag. Prevent this by disallowing "-" as the first
character of the flag's value.

A misconfigured compiler may pass extraneous implicit link directories
to its linker. If they are in `CMAKE_<LANG>_IMPLICIT_LINK_DIRECTORIES`,
CMake may generate extra `-L` flags on mixed-language link lines that
break linking. Add an environment variable that users can set to work
around such misconfiguration of their compilers.
Since commit 79921fb00c (IntelLLVM: Set linker to compiler driver for
Windows, 2021-10-19, v3.23.0-rc1~127^2) we default to the compiler
driver as linker for executables, shared libraries, and static
libraries. Not doing so for shared modules was an oversight. Copying
the shared library command line for shared modules fixes the problem
(and also is what we do for MSVC).
The MSVC linker is fine for many cases, however it does not support GPU
offload code generated by the IntelLLVM compilers. Using the compiler
driver as linker, or at least a linker that understands the object
format, is required for linking shared modules that use GPU offload
(e.g., with SYCL or OpenMP).

When UPDATE_DISCONNECTED is true, create separate update_disconnected
and patch_disconnected targets which have ALWAYS set to false.
Make the configure step depend on patch_disconnected in this case too.
This ensures the configure, build, install and test steps are not
executed unnecessarily when updates are disconnected.
Make the update and patch commands depend on the details of those
steps. This ensures they are re-executed when any of those details
change, even if updates are disconnected.
Allow updates to occur even if UPDATE_DISCONNECTED is true, but don't
contact the remote in that case. If asked to update to a ref that isn't known
locally, that is now detected and causes a fatal error when updates are
disconnected. Previously, the build would have silently and erroneously
continued to use the old ref.

When the user has specified the OpenSSL installation root directory,
through the variable OPENSSL_ROOT_DIR or the environment variable with
the same name, trust it, don't try to find OpenSSL anywhere else.

Since commit 8f82e755f3 (Ninja: Fix detection of MSVC showIncludes
prefix in Italian, 2023-01-26, v3.26.0-rc1~20^2) our regex no longer
matches the output from `msvc-wine`, which uses forward slashes:
Note: including file: /path/to/foo.h
`cl /showIncludes` under Wine prints paths of the form `Z:\path\to\file`,
but the `msvc-wine` wrapper converts them to the form `/path/to/file` so
that native Ninja can be used. Update our regex to match the prefix
followed by a path with a leading forward slash.

The problem fixed by commit c0b749cf62 (ExternalProject: Always add a
command to a step, 2014-11-05, v3.2.0-rc1~402^2~3) may occur for an
empty `COMMAND ${touch}` too, so avoid specifying any `COMMAND` at all
if there is no touch command.
FreeBSD installs both LLVM and gcc with tools named after the
major version, in the form "clang<major>", such as "clang16".
Detect compilers named this way, and find the related toolchain
tools.
