Before it would result in us writing the unescaped backslashes to
`CMakeCXXCompiler.cmake` resulting in invalid escape characters causing
the configure to error out.
Several problems with this feature came up while testing 4.3.0-rc1.
These include both broken stdlib distributions and regressions in our
implementation of the feature since CMake 4.2.
Revert commit 70c1f0f43d (Experimental: Remove import std experimental
gate, 2026-02-04, v4.3.0-rc1~61^2) except for its incidental fixes.
Remove the 4.3 release notes related to `import std`.
Rotate the experimental gate's UUID.

The LunarG Vulkan SDK on Windows provides arch-specific library
directories for cross-compiling. On X64 hosts it provides `-ARM64`
directories. On ARM64 hosts it provides `-X64` directories.
It also provides arch-specific `bin` directories, but only for the
`.dll`s of the cross architecture. We still want the plain `bin`
directory containing host-architecture executable tools.

In commit 12ec3270c4 (GenerateExportHeader: Extend documentation,
2025-05-06, v4.1.0-rc1~214^2) we added a `BASE_DIRS` example value using
a generator expression that cannot be correctly consumed after export.
Update the example to use `CMAKE_CURRENT_BINARY_DIR`, which is where
`generate_export_header` places the header anyway. Also drop the
explicit `target_include_directories`, as it is not needed when
using a file set for the header.
Closes: #27620
The fastbuild generator uses clui.dll directly, and assumed it is in
the 1033/ subdirectory. But this doesn't exist on non-US installations
of Visual Studio. With this patch cmake searches for clui.dll, so it can
use the correct path. If the env. var VSLANG is set, it tries that first,
then it tries 1033/ and if none of the two exists, it takes the first
one it finds.
Fixes: #27535
On windows when you run `nvcc -v` all the env variables will
be printed before nvcc verbose output. This allows us to handle
the cases where env variable exists with the same name as a magic
nvcc keyword we parse
Teach our CMake lexer to recognize `[[...]]` multi-line strings, as used
in some 'check source compiles/runs' examples to pass literal C/C++ code
through a CMake function. Previously, this resulted in the lexer trying
to parse such code as CMake, which is obviously incorrect. Also, use the
new `[[` syntax in more places.
Note that, because `[[...]]` can also show up in some instances denoting
optional arguments, we only consider `[[` with no `=` as a string if the
`[[` is followed by a non-identifier character. This heuristic seems to
work for most existing usages.

And change checks to look for a value rather than definition. This fix
keeps the same set of test cases in `RunCMake.CXXModules` selected as
before.

Update the list of known versions.
Run the command
cmake -DBOOST_DIR=/path/to/boost_1_90_0 \
-P Utilities/Scripts/BoostScanDeps.cmake
to extract dependencies from the 1.90.0 source tree.
They differ from 1.89's dependencies only in that
a new Boost.Cobalt component was added.
Update the list of known versions.
Run the command
cmake -DBOOST_DIR=/path/to/boost_1_89_0 \
-P Utilities/Scripts/BoostScanDeps.cmake
to extract dependencies from the 1.89.0 source tree.
They are the same as 1.88's dependencies, so just update
the version check for warning about newer versions.
The TU for Rust is a crate, not per-source. `rustc` expects entry file
to TU as input, and cannot work with object files. So we need to have
one-step build/link in most cases, similar to what old Swift was doing.

Previously, `CMAKE_<LANG>_LINK_FLAGS` was an undocumented variable used
for linking executables only. Re-spell that variable mirroring the
existing spellings for shared and module libraries, and add policy
CMP0210 to preserve compatibility.
Then, repurpose `CMAKE_<LANG>_LINK_FLAGS` to provide a variable to be
used for per-language link flags for all target types, along with a
per-configuration variant. These are added to the `<LINK_FLAGS>` rule
placeholder in the generators.
