Add a way to specify, in a portable way, to raise an error for any
warning during the link step. For that purpose, define:
* CMAKE_LINK_WARNING_AS_ERROR variable
* LINK_WARNING_AS_ERROR target property

On modern macOS, compiler wrappers like `/usr/bin/cc` automatically
choose a SDK to pass via `-isysroot` to an underlying compiler from
Xcode or the CommandLineTools. Other toolchains like Homebrew's `gcc-*`
come with a default SDK too. Therefore, when targeting macOS, we no
longer need to choose any SDK or pass an `-isysroot` flag by default.
Update initialization of `CMAKE_OSX_SYSROOT` to be empty by default when
targeting macOS.
Fixes: #19180
Revert commit 1f085e11e4 (OS X: Resolve compiler in /usr/bin to that
reported by Xcode xcrun, 2015-01-03, v3.2.0-rc1~126^2~1). The compilers
in Xcode cannot be used by build systems that do not add an `-isysroot`
flag.
Issue: #19180
This boolean setting allows parallel building to be disabled for
individual source files built via `add_custom_command`. Using this
option is equivalent to setting policy `CMP0147` to the `OLD` behavior.
Closes: #26413
This behavior was removed when we switched to libuv in CMake 3.11.
After backporting new changes from libuv v2, we can restore the
behavior.
Fixes: #20115
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
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.

Traditionally CMake generates link lines by starting with the direct
link dependencies specified by `LINK_LIBRARIES` in their original order
and then appending indirect dependencies that the direct dependencies
do not express. This gives projects control over ordering among
independent entries, which can be important when intermixing flags
and libraries, or when multiple libraries provide the same symbol.
However, it may also result in inefficient link lines.
Add support for an alternative strategy that can reorder direct link
dependencies to produce more efficient link lines. This is useful
for projects that cannot easily specify their targets' direct
dependencies in an order that satisfies indirect dependencies.
Add a `CMAKE_LINK_LIBRARIES_STRATEGY` variable and corresponding
`LINK_LIBRARIES_STRATEGY` target property to select a strategy.

If the connection fails in a way that might be a certificate error, and
verification was enabled by the new default, mention environment
variable `CMAKE_TLS_VERIFY` in the diagnostic to help users that were
relying on the old behavior turn off server certificate verification in
their environment.
Fixes: #23608
The file generated by install(EXPORT) computes _IMPORT_PREFIX
in a way that assumes a normalized path. If the DESTINATION
contains any ../ components, the computed _IMPORT_PREFIX
would be wrong. Force the DESTINATION path to be normalized,
subject to the new CMP0176 policy.
Also normalize all other DESTINATION paths for consistency,
except for INCLUDES DESTINATION, which is not strictly a
destination but rather a search path to add.
Fixes: #26252
Windows is heading toward making UTF-8 the preferred MBCS. As CMake's
internal encoding, `UTF-8` is effectively equivalent to `NONE`, which
was CMake's behavior prior to 3.15's accidental change to `AUTO`.
Behavior of `ENCODING UTF-8` is independent of CMake's internal
encoding, making it in principle a better default than `NONE`.
Add policy CMP0176 for compatibility and to document the default's
history.
