Upcoming versions of nvcc are adding support for `SYSTEM_INCLUDES`
which contain includes that are implicitly used with `-isystem`
instead of `-I`.
Support of this is needed in CMake as some CUDA Toolkit releases will
start to have a different include directory layout and using only the
output from `INCLUDES` will be insufficient to find all headers.
Clang before 20.1 does not recognize sm_100 and newer. Revise:
* commit b2251e0deb (CUDA/Clang: Update architectures supported by
CUDA 12.8, 2025-02-04, v4.0.2~4^2~1^2)
* commit a1b4c30f24 (CUDA: Add CUDA 12.9 new architectures and family
syntax, 2025-04-21, v4.0.2~3^2^2)
Starting with version 3.14, on Windows, by specifying macro Py_NO_LINK_LIB,
the python library is no longer implicitly specified at the link step.
Fixes: #26756
As outlined in the CUDA 12.9 release notes sm_5X, sm_6X, and sm_70
are being removed in CUDA 13:
> Maxwell, Pascal, and Volta architectures are now feature-complete with
> no further enhancements planned. While CUDA Toolkit 12.x series will
> continue to support building applications for these architectures,
> offline compilation and library support will be removed in the next
> major CUDA Toolkit version release.

LLVM/Clang 20, when invoked as `clang++ -E -c ...`, now warns:
warning: argument unused during compilation: '-c'
Drop the unnecessary `-c` flag. Also add a `-w` flag to suppress
warnings so their text is not parsed as predefines.
This makes the default CUDA architecture consistent across compilers,
and makes it more likely that the resulting binary will run on the
user's hardware.
This also makes hardware requirements for CI builds more consistent.
See commit 4f2178c4a8 (ci: add tags to tie CUDA jobs to runners with
hardware supporting them, 2025-04-21).
In commit f69b9b7305 (CUDAToolkit: Restore ability to find cupti
headers, 2023-12-08, v3.28.1~8^2) we did not update the CUPTI library
searches to add the extra search path needed for certain install layouts
(only the header search path). Add the additional library search paths.

Previously we saved it in the cache, which:
* Persists even if a new version of CMake changes how the check works.
* Does not propagate to `try_compile` checks.
Revert commit b3f1c60aff (MSVC: Use -std:c++23preview flag for C++23
when available, 2025-03-12), except for the VS flag table update.
MSVC documentation states that the flag will be removed in the future
when `-std:c++23` is added. Therefore it is only suitable for manual
specification by end-users.

The initial compiler support implemented in commit 9ba0a54554 (TIClang:
Add support for TI Clang-based compilers, including tiarmclang,
2023-12-06) introduced `Arm` as architecture instead of `ARM` which is
used for all other compilers.
Add Swift linker information modules missed by commit c1c4cf9545 (Linker
configuration: introduce a new architecture, 2024-06-05,
v3.31.0-rc1~307^2~1) and needed since commit 1e35163ae8 (WHOLE_ARCHIVE
link feature: rely now on linker configuration, 2024-07-01,
v3.31.0-rc1~307^2).
Fixes: #26657
Revise commit fc7aa3cd69 (tests: Preserve empty arguments in test
command lines, 2024-09-30, v3.31.0-rc1~33^2) to delay variable expansion
until code evaluation. Otherwise we may parse the working directory
path as CMake language code.
The implementation in commit 564d527c04 (IAR: Improve error message for
missing license, 2024-08-12, v3.31.0-rc1~234^2) failed for corner cases
in which symlinks were used from a location different from the one in
which the toolkit is shipped with (`<target>/bin`).
In this new implementation, the `<target>` architecture is taken solely
from the compiler NAME itself for all the supported languages and
forwarded to its respective BinUtils executable names
(e.g., `icc<target>`, `iasm<target>`, `a<target>`). This decouples the
location from the subdirectory in which they should be found.
Fixes: #26610
Fix use of the `signature::` directive by commit ae558b9ad0 (FindMatlab:
Support REGISTRY_VIEW, 2024-02-08, v3.30.0-rc1~528^2). The directive
was created for use inside `Help/command/*.rst` documents. Using it
in module documentation requires explicit anchors.
In commit cfa888a6e2 (Clang/CUDA: Add language-wide flags when linking
with compiler driver, 2024-10-07, v3.31.0-rc1~12^2) we added the wrong
placeholder to `CMAKE_CUDA_CREATE_SHARED_LIBRARY` to represent the
language-wide flags. The `<FLAGS>` placeholder is for executables.
The `<LANGUAGE_COMPILE_FLAGS>` placeholder is for shared libraries.
The distinction is for historical reasons.
Fixes: #26563
This was added in commit 98d0f918ba (LFortran: Add support for this
compiler, 2024-01-25, v3.31.0-rc1~303^2~2) because it is needed for
cases covered by CMake's Fortran tests. However, it does not work
with Fortran modules and breaks lfortran's own `examples/project1`.
Move the flag to the test cases that need it, just as the original
commit did with `--implicit-interface`.

Update the list of known versions.
Run the command
cmake -DBOOST_DIR=/path/to/boost_1_87_0 \
-P Utilities/Scripts/BoostScanDeps.cmake
to extract dependencies from the 1.87.0 source tree.
Dependencies differ from 1.86:
* Boost.Log no longer depends on Boost.Chrono

Since commit 474eafe28c (clang-cl: Add support for C++23, 2024-09-13,
v3.31.0-rc1~97^2) we use a Clang-specific flag to enable C++23 since
`clang-cl` has no `-std:c++23` flag, and `-std:c++latest` may enable an
even newer version of C++. However, in `.vcxproj` files there is no way
to express a target-wide `-clang:-std=c++23` flag for only C++ sources
when the target also has C sources. Add a special case to map back to
`-std:c++latest` for targets with C++23 and C together.
Fixes: #26508
The GNU `ld(1)` manual documents the `--dependency-file=depfile`
single-argument form of the flag. Prefer it over the multi-argument
`--dependency-file depfile` form so that only one argument needs to be
passed through the compiler driver by `-Wl,` or equivalent. This may
improve diagnostics in cases where it is unsupported, making them easier
to diagnose.
