Teach `export()` and `install(EXPORT)` to record this setting on the
imported targets they generate. Make this property's non-presence
authoritative on imported targets since they represent what was built
elsewhere.
There is an inadvertent inconsistency in the notice for the CPS export
experimental feature as compared to other experimental feature notices.
Change it to be consistent.
Since commit 84db8506ff (Deprecate compatibility with CMake versions older
than 3.10, 2024-10-03, v3.31.0-rc1~23^2) the `cmake_minimum_required` and
`cmake_policy` commands warn if the project does not enable policies as
of 3.10 or higher. Clarify the advice given in the warning message about
how to update the version specification, particularly without actually
requiring a newer minimum version of CMake.
There's no need to check if flushing is needed after every command
is added to the variable holding the script content. It is enough to only
check once per test name. This simplifies the flushing logic, removing
the need for a separate flush_script() command. Previously, we were
not clearing the flushed script contents in all cases, but this is now
rigorously enforced at the one location where flushing is performed.
Also simplify the flushing of the list of test names, since that too doesn't
need a separate command. It is simpler and safer to handle that
directly inline where the one call to flush_tests_buffer() was
previously being made.

When a single-value keyword is repeated, and the first instance is
missing a value, it prevents the value from the second instance from
being stored in a variable. This was a regression introduced by
commit ceeea4e511 (cmake_parse_arguments: Set variable if empty string
given after keyword, 2024-08-18). That change also didn't create a
variable if the keyword was given but without a value. The purpose
of the change was to always define a variable if a keyword was given.
Lastly, that change didn't protect the CMP0174 logic to make it only
apply to the PARSE_ARGV form.
The first two of the above problems are fixed here by tracking the
keywords given instead of checking which keywords were missing
values. The third problem is also fixed here, being tightly coupled
to the same logic as the first two problems.

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.

Follow up the python 3.13 and 3.14 support from:
* commit be958c8f35 (FindPython: Add support for Python 3.14, 2024-10-17)
* commit dfab044c44 (FindPython: add support for Python 3.13, 2023-08-14)
with an update for the FindBoost test.
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
Add documentation to clarify that `find_package` searches paths in the
specified order and stops at the first match. Clarify documentation of
`CMAKE_FIND_PACKAGE_SORT_*` to match the actual behavior.
Note that no behavior is actually changed, this merely improves the
documentation to reflect actual behavior rather than seeming to imply
something else.
Also, update the test to verify that what we claim in the updated
documentation is what's actually happening.
The default behavior of bin2c is to create binary arrays that have no
null termination. So to use it as a C array we need to explicitly tell
it to create valid null terminated strings.
This will safely allow us to run PTX tests across all CUDA drivers.
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: #25714
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.
Fixes: #26355
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).
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.
