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
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.

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.
Fixes: #26262
Add a new CMP0175 policy to preserve backward compatibility
for projects that were using unsupported keywords or arguments.

Detect Windows Kernel-Mode Driver include directories and library search
paths from the WDK command-line environment. Require toolchain files to
specify the KMDF target version via a new variable.
Since this changes the behavior of the WindowsKernelModeDriver
experimental feature, update its UUID.
This includes the target property, its initializing variable, its
initializing environment variable, and updating related docs to mention
the new bits.

If a single-value keyword is followed by an empty string, the
command unsets the variable for that keyword instead of setting
it to the empty string. This is inconsistent and unexpected. Add
policy CMP0174 which ensures the variable for a single-value
keyword is always set when any value is given, not just for a
non-empty value.
The new CMP0174 policy only affects the PARSE_ARGV form of
cmake_parse_arguments. The older form silently drops all empty
string arguments before processing the argument list.
Fixes: #25972
Preset environment variables are always set to the exact value
specified. The `$penv{}` macro can be used to refer to the parent
environment value to append or prepend to it.

* Wraps the llpkgc parser with cmPkgConfigParser

the assumption additional subcommands will be added soon.
* Adds various tests for the above
Add a `-LR[A][H] <regex>` flag with similar functionality to `-L[A][H]`,
but instead of listing all cached variables, it show only specific
variables that match the name regex.
Add policy CMP0172 to set `CPACK_WIX_INSTALL_SCOPE` to `perMachine` by
default. Follow up commit 60661f6770 (CPack/WiX: Make InstallScope
