On platforms that semantically distinguish loadable modules (plugins)
from shared libraries, such as macOS and CYGWIN, fix the per-language
fall back to create them the same way as with the C toolchain even when
the C language has not been enabled.
The `Platform/<OS>.cmake` modules record platform-specific flag
variables for the C toolchain. The `CMake<LANG>Information` modules
initialize the per-language platform-specific flag variables to defaults
copied from C. However, they have diverged over time, and not all
platform-specific flag variables are initialized correctly for all
languages. Factor out the CXX language's instance of this logic into a
helper macro, and reuse it for all languages for which we previously
had the platform-specific flag variables at least partially filled out.
Previously the Fortran language's copy of this logic used
`if(NOT DEFINED <var>)` instead of just `if(NOT <var>)` to allow
`Platform/<OS>-<COMPILER_ID>-<LANG>` modules to specify empty values for
some platform-specific flag variables without being overridden.
Use this approach in the helper macro so it applies to all languages.

6e5e7968c3 GenEx $<LINK_LIBRARY>: Add the support of properties attached to features
Acked-by: Kitware Robot <kwrobot@kitware.com>
Merge-request: !9510
Top-level code only works as part of executables, which breaks when
`CMAKE_TRY_COMPILE_TARGET_TYPE` is set to `STATIC_LIBRARY`. This patch
fixes the test to something agnostic between executables and libraries
while still verifying that we can import types from the standard
library.

Revert commit cabad8a37f (ExternalProject: Always use $<CONFIG> for
source files, 2023-02-02, v3.27.0-rc1~550^2~3) and restore
Xcode-specific behavior intentionally preserved by commit c111d440ce
(ExternalProject: Express per-config step stamp file paths using CONFIG
genex, 2022-06-08, v3.24.0-rc1~15^2). Unfortunately we still do not
have a test case, so leave a comment to avoid reverting this.

Add the following variables:
* Python_EXECUTABLE_DEBUG
* Python_INTERPRETER
* Python_DEBUG_POSTFIX
and target Python::InterpreterDebug.
python_add_library() command Manage DEBUG_POSTFIX target property based
on the value of Python_DEBUG_POSTFIX variable.

The C++ sources we use to test the compiler do not use modules.
Avoid requiring a compiler that can scan just to enable the language,
even when CMP0155 is NEW. The project may explicitly turn off
`CMAKE_CXX_SCAN_FOR_MODULES` before adding any targets.

Upstream Boost 1.70 and above provide a proper `BoostConfig.cmake`
package configuration file. Packages for all major distros now
provide it in at least one LTS release. Add a policy to pretend
that the `FindBoost` module does not exist so that projects calling
`find_package(Boost)` use the upstream package directly.
Closes: #19402
CPack no longer blindly tries to create temporary packaging
(sub)directories that contain the verbatim name of a component, which
might contain characters that are not supported on the platform /
filesystem.
Instead, if the component's name contains a (possibly) problematic
character its MD5 hash will be used for that temporary packaging
(sub)directory.
Likewise, if the component's name resembles a reserved device name (e.g.
"COM1" on Windows) then the temporary packaging (sub)directory will get
this name prefixed with an underscore.
Similar, if it ends in a dot (on Windows) then the temporary packaging
(sub)directory will get this name suffixed with an underscore.

Add a variable to indicate the latest standard known to be supported for
each language:
* `CMAKE_C_STANDARD_LATEST`
* `CMAKE_CXX_STANDARD_LATEST`
* `CMAKE_CUDA_STANDARD_LATEST`
* `CMAKE_HIP_STANDARD_LATEST`
* `CMAKE_OBJC_STANDARD_LATEST`
* `CMAKE_OBJCXX_STANDARD_LATEST`
These variables, more generally referred to as
`CMAKE_<LANG>_STANDARD_LATEST`, are assigned an integer value which
represents the minimum between the latest version of the associated
language standard supported by the current compiler and the latest
version supported by CMake.
Add documentation for these variables in a new page called
`CMAKE_<LANG>_STANDARD_LATEST` was added under the "Variables for
Languages" section of the `cmake-variables(7)` page.
Update each compiler-specific CMake script under
`${CMAKE_ROOT}\Modules\Compiler` to manually define the relevant
`CMAKE_<LANG>_STANDARD_LATEST` variable as necessary. This will
require updating and maintaining as newer compiler versions become
recognized by CMake.
Closes: #25717
Set the requirement for Objective C 23 support for AppleClang to
`11.0.3` in `${CMAKE_ROOT}\Modules\Compiler\AppleClang-OBJC.cmake`.
This is consistent with the requirement for C 23 support as
indicated in `${CMAKE_ROOT}\Modules\Compiler\AppleClang-C.cmake`.
Unset irrelevant compile option variables in the following scripts:
* `${CMAKE_ROOT}\Modules\Compiler\ARMClang-C.cmake`
* `${CMAKE_ROOT}\Modules\Compiler\TIClang-C.cmake`
* `${CMAKE_ROOT}\Modules\Compiler\TIClang-CXX.cmake`
These scripts all include either
`${CMAKE_ROOT}\Modules\Compiler\Clang-C.cmake` or
`${CMAKE_ROOT}\Modules\Compiler\Clang-CXX.cmake`, and those scripts
will set various compile option variables based on what the
standard version of Clang supports. However, these do not
necessarily apply to ARMClang and TIClang. This commit thus
explicitly unsets all of the compile option variables which are not
manually defined for these compilers.
Fat LTO objects contain both traditional object code and the LTO bitcode
IR, but the GNU compiler does not support them on Apple platforms.
A compile error is raised when `-f[no-]fat-lto-objects` flags are used,
so avoid them.
This also implies that static Fortran libraries cannot be built with IPO.
Fixes: #25931
If the project builds with `-Wmissing-prototypes` to catch unnecessarily
exported symbols, `CheckForPthreads.c` will fail to build. Fix this by
marking `start_routine` as static.
