These were excluded with the XL and XLClang compilers because one
such compiler in nightly testing hard-codes `--enable-new-dtags`.
Add a way to disable the cases via local configuration instead so that
we can run them on the rest of the XL compilers.
This fixes incorrect runtime dependency resolution when the dependency
is located in rpaths of a transitive parent. Instead of supplying only
the rpaths of the immediate parent, it combines the rpaths of all
transitive parents and passes them down.
Fixes: #24172
The values of the cmTargetPropCommandBase::ArgumentFlags enum
are combined in boolean OR and AND operations in various places.
That used to be valid, but some values were added over time which did
not preserve support for such boolean logic. Update the enum values
such that they are increasing powers of 2 to restore that capability.
Fixes: #24199
Since commit 0c141b0393 (try_compile: Record output location instead of
reverse computing it, 2022-08-31, v3.25.0-rc1~154^2) we always look for
the "Debug" configuration's output binary from the test project.
Restore looking for the `CMAKE_TRY_COMPILE_CONFIGURATION`.

Evaluate and expand generator expressions in the `COMMENT` argument of
the `add_custom_command()` and `add_custom_target()` commands.
This allows to include generator expressions, e.g. a targets location
$<TARGET_...> or the current configuration $<CONFIG>, in the build-time
messages.
Fixes#22507
Previously we added the language standard flag near the end of all
options, even after those added by `add_compile_options` and friends.
However, on some compilers such as MSVC, the `-std` flag may reset
defaults for flags that precede it on the command line. Move the
language standard flag to before all other flags that CMake adds for
other abstractions, and before those added by `add_compile_options`.
`CMAKE_<LANG>_FLAGS` should still precede the language flags though,
because they are meant to be treated as language-wide modifications to
the compiler defaults, similar to `$CC $CFLAGS`.

Since commit 37da6af17d (find_dependency: Always search dependencies,
2019-03-29, v3.15.0-rc1~301^2) we search for a package every time it is
encountered in the transitive dependency graph traversal, even if it has
been found before. This was done in case a new visit to a given package
requests different components than a previous visit. However, it also
causes a lot of repeat processing that is unnecessary in the common case
that all calls share the same set of components (often none).
Restore the logic to avoid repeating the search for an already-found
package. Handle differences in components by de-duplicating based on
the complete `find_package` call arguments.
Fixes: #23685
