Some newer compilers warn in situations where the returned local
variable could be movable, but a C++11 defect meant older compilers
may still return a copy when a type conversion is involved. Adding
the suggested std::move prevents that warning on that compiler, but
creates a new warning on others. Constructing the actual return type
explicitly with the suggested std::move on the constructor argument
keeps both sets of compilers happy.
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.
Issue: #23200
When evaluating the `$<CONFIG>` genex on an imported target has the
`IMPORTED_CONFIGURATIONS` property set, the current project has a config
that does not match any of those, and no explicit configuration mappings
are defined, fall back to the same configuration as `IMPORTED_LOCATION`.

Update the `TryCompileCode` signature to allow callers to distinguish
between administrative failures and a compilation failure. Return
results in a structure to which more information can be added later.

Previously, MAKE_DIRECTORY would print `problem creating directory: {}`,
which was very unhelpful for debugging. Extend the message with the
OS error string.
On AIX, including `<curses.h>` includes `<term.h>` which defines
a bunch of non-prefixed, lower-case macro names. Undefine one
that conflicts with our source code.
Fixes: #24229
VS 2017 and above come with a Visual Studio Installer tool that tracks
four-component Visual Studio version numbers. We already detect the VS
version number because it is needed to make some generation decisions.
Provide the number to projects in a `CMAKE_VS_VERSION_BUILD_NUMBER`
variable so they can use it similarly.
