Since commit 7abd3137b7 (Linking: Optionally reorder direct dependencies
from LINK_LIBRARIES, 2024-09-19, v3.31.0-rc1~53^2) the strategy name
`PRESERVE_ORDER` has led users to expect that it strictly preserves
order. While the part of the link line generation logic controlled by
`LINK_LIBRARIES_STRATEGY` does preserve order, it is not the last step.
Toolchain-specific de-duplication can cause the order to change on the
actual link line generated in the build system.
Rename the strategies:
* `PRESERVE_ORDER` => `REORDER_MINIMALLY`
* `REORDER` => `REORDER_FREELY`
The new names make it clear that reordering is always possible, just to
varying degrees. Update the `LINK_LIBRARIES_STRATEGY` documentation to
clarify that the strategies do not directly control the final link line.

When using the WindowsKernelModeDriver, do not add the new paths
if the variable was not previously defined. Instead, append them
to the existing value.
Add a new GUID for the Experimental mode gate
The linker configuration file is now optional: It is loaded only if
variable CMAKE_<LANG>_USE_LINKER_CONFIGURATION is set to TRUE.
The file CMakeAddNewLanguage.txt is updated to take into account the
linker configuration.

Fix a small bug in cmExportPackageInfoGenerator that caused extended
version properties ("compat_version", "version_schema")) to be emitted
when empty. Add a test to ensure this is working as intended.

Revert commit 502610733f (Ensure imported targets in sibling dirs are
deduplicated, 2024-09-15, v3.31.0-rc1~92^2). Also revert the change
from a copy of the logic made by commit cd418d4bb6 (Static libraries
de-duplication: keep first occurrence, 2024-09-29, v3.31.0-rc1~30^2).
The logic was de-duplicating based on the target name rather than based
on the library file path.

Re-introduce the behavior originally introduced in CMake 3.30.3 by
commit c1ece78d11 (project: non cache <project> prefix variables are
also created, 2024-08-27, v3.30.3~2^2), but this time with a policy for
compatibility.

Issue: #26243
The change in commit 86ad7cc886 (project: Only define non-cache vars if
already defined, 2024-09-15, v3.30.4~2^2) was meant to only check for
non-cache variables when deciding whether to set non-cache project
variables for the current call. However, it erroneously checked for any
variable, including cache variables. This gives the intended result on
the first run, but on subsequent runs a cache variable will exist that
did not on the first run, leading to different behavior between the two
runs. Fix the logic to only check for a pre-existing non-cache
variable, as was originally intended.

Merge-request: !9875
Issue a deprecation warning on calls to `cmake_minimum_required` or
`cmake_policy` that set policies based on versions older than 3.10.
Note that the effective policy version includes `...<max>` treatment.
Update the check from commit 3a4791548d (Deprecate compatibility with
CMake versions older than 3.5, 2023-02-09, v3.27.0-rc1~508^2).
The `/usr/lib` and `/lib` entries need to be present, but do not need to
be at the end. Avoid appending extra copies of the entries if they
already exist.
Closes: #26275
This will now preserve empty values in the TEST_LAUNCHER and
CROSSCOMPILING_EMULATOR target properties for tests added by:
- The add_test() command.
- The ExternalData_Add_Test() command from the ExternalData module.
- The gtest_add_tests() or gtest_discover_tests() commands from the
GoogleTest module.
For the gtest_add_tests() and gtest_discover_tests() commands,
empty elements in the values passed after the EXTRA_ARGS keyword
are also now preserved.
Policy CMP0178 is added to provide backward compatibility with the
old behavior where empty values were silently discarded from the
above cases.
Fixes: #26337
Visual Studio Generator: The `VS_TOOL_OVERRIDE` source file property
would previously only be respected for file types that CMake didn't know
how to build out of the box. This change allows the user to override how
any source file is built with a custom build tool, even ones with
standard/recognized extensions such as `.cxx`, `.idl`, etc.
Fixes: #26336
