Add import/export support and documentation for the SPDX_LICENSE
target property. A target's license can be specified by setting
this property to an SPDX license expression. CMake and CPS-format
export files generated with `export()` or `install()` will
retain the license information. CMake also imports the license
property for imported targets.

On Windows, the only reliable way to read/write Unicode text from/to a
Console is to use `ReadConsoleW` and `WriteConsoleW` and convert from/to
wide-character encoding. When `cin`, `cout`, and/or `cerr` are attached
to a Windows Console, use a custom C++ `streambuf` to handle the I/O.
This will replace KWSys ConsoleBuf, whose implementation is more complex
to support narrow output streams on Windows non-UTF-8 narrow encodings.
We only need to support UTF-8.

Provide a useful warning if an invalid UUID is given in a
`CMAKE_EXPERIMENTAL_` variable. This can occur if a different CMake
version is used than the one that the feature was implemented with, or
if there is a simple typo in the value. It should reduce confusion with
the use of experimental features.

Test behavior with `Find` module packages which chain to config modules.
This emulates CMake's shipped modules which support config packages
provided by modern upstreams.
Move logic from commit c85524a94a (Ensure stdin, stdout, and stderr pipes
are always open, 2019-05-02, v3.15.0-rc1~171^2) and commit 96010cc968
(Ensure stdin, stdout, stderr FILE streams are open on Windows, 2024-01-24,
v3.29.0-rc1~65^2) to a dedicated source. Expose it through an `Init` class
constructor to make it optionally available during static initialization.

Finding small errors in `RunCMake` outputs against the output is a
tedious task. Add a small tool that sets up a simple `tmux` window setup
to help debug them.
EXCLUDE_EMPTY_DIRECTORIES option excludes empty directories under the
directory to install. A directory is considered not empty if and only if
the directory contains at least one file or one symbolic link or one
none-empty sub-directory.
Closes: #19189
CMake detects libraries that the compiler driver implicitly passes to
the linker, and stores them in `CMAKE_<LANG>_IMPLICIT_LINK_LIBRARIES`
for use in constructing mixed-language link lines. Some compiler driver
flags add implicitly linked libraries that should not be used during
mixed-language linking because they are handled by similar flags passed
to the other language's compiler driver. Add an environment variable
that users can set to avoid undesired implicit link libraries in such
scenarios.
Follow the pattern from commit 023de565d3 (Optionally exclude implicit
link directories via environment, 2023-05-25, v3.27.0-rc1~54^2).
Fixes: #26911
In commit 459d1cc095 (Tests: Verify that linker tool is detected and
identified where expected, 2023-12-13, v3.29.0-rc1~176^2) we renamed the
inspection result variables but did not update `ExcludeDirs`.
This deprecates the protobuf_generate_cpp() and protobuf_generate_python()
commands because the protobuf_generate() can work for both of these
cases and provides more options. Also, upstream Protobuf CMake-based
build system has marked these two commands as legacy and requires
setting a separate protobuf_MODULE_COMPATIBLE variable to boolean true
before calling the find_package(Protobuf).
Changes:
- Reworded and synced module documentation with other similar find
modules.
- Imported targets moved to top.
- Moved examples to a separate section.
- Extended examples with basic usage and some quick hints how to upgrade
deprecated commands to protobuf_generate().
- Used lowercase style of commands.
- Used "commands" instead of "functions" or "macros".
- Documented the DESCRIPTORS argument for protobuf_generate() command
and added a note that this option is not available when Protobuf is
found in config mode.
- Added a note about the Protobuf CMake-based build system and that
probuf_generate*() commands might come from the upstream CMake config
files. Mentioned also the protobuf_MODULE_COMPATIBLE variable from
upstream CMake build system.
See #21228.
This fixes this issue in favor of #24321 which tracks further
progress about Protobuf.
- Documented the missing `PROTOBUF_GENERATE_CPP_APPEND_PATH` variable.
See #19968.

Since commit 6baf65ec46 (ASM: Do not consider MSVC C/CXX compiler for
generic ASM, 2025-04-08) we no longer mistake `cl` for an assembler.
However, some projects unconditionally enable ``ASM``, which worked
on Windows only due to that bug. Restore compatibility with such
projects by guarding the change behind a new policy ``CMP0194``.

In commit 7b19531291 (macOS: Do not pass any SDK/-isysroot to compilers
by default, 2024-11-06, v4.0.0-rc1~511^2) we broke support for using
upstream LLVM/Clang to build for macOS because the compiler has no
default sysroot. Handle empty `CMAKE_OSX_SYSROOT` with LLVM/Clang by
falling back to the macOS SDK reported by `xcrun --show-sdk-path` .

CPS names look like `[package]:component`, which needs to get mangled
into `package::component` to match CMake's convention. This was
implemented correctly for fully qualified component requirements, but
relative names were not being properly mangled. Adjust handling of
relative names to correctly translate from CPS to CMake convention.

- Do not try to guess the flags to pass to "cmake -E tar" ("z" or not) based
on the extension. It is not necessary, as the archive type is autodetected
since we switched to libarchive.
- Add new tests for .tar.zst archives, which would fail without the change.
Fixes: #25062
Record `find_` command events in the configure log, except
`find_package` as it is far more complicated (and will have its own
event kind).
Note that testing only generates the events of interest, there is no
verification. Also note that testing that the "found" to "notfound"
transition causes an event is not testable because a truthy value in the
variable skips any kind of verification or other logic beyond
normalization.
