The pattern `extern "C" { inline bool operator==(...) {} }` appears
in at least one Windows SDK header, `winnt.h`. Translation units that
instantiate the inline symbol produce object files with a symbol named
just `==`. Avoid exporting such symbols because the linker will not
recognize them.

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.

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.

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.

149ee3b4bc Xcode: Use DEBUGGER_WORKING_DIRECTORY as a fallback for scheme work dir

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``.
Fixes: #26907

This also means when XCODE_SCHEME_WORKING_DIRECTORY is
set and a Xcode generator is used, that property will be used when
writing the debugger field in the file API replies.

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` .

In commit e90f60f864 (find_package: Don't glob certain macOS paths,
2024-10-23, v4.0.0-rc1~579^2~1) we changed the name matching logic of
`find_package` to check if a possible match is a directory before
checking whether the name is a match. In some situations, this results
in unnecessarily calling `stat` for a very large number of files, which
can be extremely slow on some systems (especially Windows). Fix this by
making the check the last thing we do before accepting a possible match.
Fixes: #26817
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.
