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.

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
Extend commit d27fe9dfba (AIX: Add option to archive shared libraries,
2024-06-18) to update the Ninja generator to support the new
`AIX_SHARED_LIBRARY_ARCHIVE` feature.
Fixes: #26332
When AIX stores a `.so` inside a `.a` archive, the loader section is
aligned to maximum of the text and data alignment. In commit 98013ad1ca
(cmXCOFF: Add support for editing binary inside an archive, 2024-07-01)
we only accounted for the data alignment.
Issue: #26275
Extend the changes from commit 190a5fdffd (Automatically use OpenSSL by
default on Linux and FreeBSD if available, 2016-02-26, v3.6.0-rc1~301^2)
and commit dd3e476786 (OpenSSL: Issue an error if OpenSSL is not found,
2019-07-17, v3.16.0-rc1~379^2) to cover builds targeting the CYGWIN and
MSYS runtime platforms.
