These extensions are used by convention for C++ module interface units
with Clang.
For now, do not add any tests using these extensions.
Very few compilers recognize them as C++ sources.
Tests can be added later as part of C++ modules support.
Since commit 18e1bfbb3c (cmake: On configure error suggest looking at
CMake*.log files, 2013-07-09, v2.8.12~210^2), when configuring a project
fails, we print `See also .../CMake{Output,Error}.log` near the end of
the output. This was intended to help users find failures in system and
compiler inspection checks, but for normal project errors the messages
may be misleading. The logs may contain incidental errors that are part
of normal operation and do not need to be addressed by the user.
Since commit f6ed2585e5 (Modules: Record system inspection steps in the
configure log, 2023-01-16), CMake's builtin modules no longer log
information to the old-style `CMake{Output,Error}.log` files anyway,
so stop mentioning them.

In order to support multiple log versions without buffering the
entire log, move versioning to the level of individual events.
Multiple versions of an event may then be logged consecutively.
Issue: #23200
Add infrastructure for a "configure log". Use YAML for a balance of
machine- and human-readability to records details of configure-time
events in a structured format.
Teach the RunCMake test framework to support matching the configure log.

Before, a documentation entry was in/out parameter.
Now it's a normal return value.
This also makes possible to eliminate defaulted default ctor
for `cmDocumentationEntry` for C++ 11.
Also, simplify `cmake::AppendGlobalGeneratorsDocumentation()`.
Use fixed size arrays of `cmDocumentationEntry` items instead of
open arrays of two `char` pointers when describe program options
help screens.
Also, drop `const char*[][2]` overloads of methods of
`cmDocumentation` and `cmDocumentationSection` classes in the sake
of generic (template) appenders introduced earlier.
Introduce a new signature for try_compile (and try_run) which removes
the `bindir` argument and requires the SOURCES tag. This will eventually
allow us to add other ways of providing sources, but also allows us to
change the behavior without breaking compatibility.
The old signature uses a special, but non-unique temporary location
inside the specified `bindir`, which conventionally is just the
project's build directory. The new signature unconditionally uses the a
unique temporary directory which is unconditionally within the project's
build directory (which is no longer separately specified). This ensures
that successive runs do not overwrite previous runs, will simplify
debugging, and should also, eventually, allow us to execute multiple
trials in parallel.

The new sub-command writes a string representation of the
current log level to the output variable given to the
sub-command.
Given that the log-level might be set either via the --log-level
command line option or via the CMAKE_MESSAGE_LOG_LEVEL
cache / regular variables, the priority for each of the log level
sources is as follows, with the first one being the highest:
1) --log-level
2) CMAKE_MESSAGE_LOG_LEVEL regular variable
3) CMAKE_MESSAGE_LOG_LEVEL cache variable
4) default log level (STATUS)
Fixes: #23572
Move LogLevel enum into the cmMessageType.h header in preparation
for a new log level querying feature.
Wrap the enum into a new Message namespace.
Adjust all code usages.
Rename the booleans 's_ErrorOccured' and 's_FatalErrorOccured' to
's_ErrorOccurred' and 's_FatalErrorOccurred', respectively.
Rename the getters and setters to 'Get[Fatal]ErrorOccurred' and
'Set[Fatal]ErrorOccurred', and fix all uses across the codebase.
Allow FetchContent_MakeAvailable() to try a call to
find_package() first, or redirect a find_package() call to
FetchContent_MakeAvailable(). The user can set variables
to control which of these are allowed or tried by default.
Fixes: #21687
