This updates the CMP0135 documentation, which should have been
done as part of c2044fdf3f (FetchContent: Respect the CMP0135 policy
setting, 2022-06-02).
Issue: #23560
The variable `CPACK_TEMPORARY_DIRECTORY` is an internal variable that is
required for proper packaging. Historically, a second variable
`CPACK_TEMPORARY_INSTALL_DIRECTORY` existed as well which had the same
purpose. Both variables had to be set to the same value. Otherwise,
CPack would not succeed with packaging.
In order to ease CPack's usage, the variable
`CPACK_TEMPORARY_INSTALL_DIRECTORY` is now no longer used.
However, as it cannot be guaranteed that neither of these two (internal)
variables have been used in the wild, some mechanism was introduced to
preserve backwards-compatibility: If one of these variables is set, the
other variable will be set to the same value. If, however, both are set
to different values, CPack still fails but with an explicit
error-message.
Fixes: #25046
By default, Ninja displays the full build command for the object which
is very verbose. Warnings are often lost in the noise, and compile
errors take some searching to find. If a build step fails, Ninja will
still print out the full build command, so there's no loss of useful
information.

Package configuration files generated by `configure_package_config_file`
set this variable in `@PACKAGE_INIT@` and then use it later. There may
be intervening calls to `find_package`, e.g., via `find_dependency`.
If the loaded package also used `configure_package_config_file`, it
may change the value of `PACKAGE_PREFIX_DIR`. Explicitly save and
restore the value to avoid this.

Filter out `-Wunused-command-line-argument` warnings from Clang (that
can be caused by user-specified flags) so that they do not break our
checks for C++ feature availability.
This extends commit 71b65abca2 (C++ feature checks: Filter out warnings
caused by user flags, 2017-09-19, v3.10.0-rc1~90^2).
Wire up the flags needed to support module libraries built and used with
Swift. We need to pass `-bundle` to the linker when linking module
libraries on Darwin, and we need to pass `-export-dynamic` to the linker
when emitting an executable that exports symbols on Linux. This patch
wires up `CMAKE_SHARED_MODULE_CREATE_Swift_FLAGS` and
`CMAKE_SHARED_MODULE_LOADER_Swift_FLAG` on Darwin, and hooks up
`CMAKE_EXE_EXPORTS_Swift_FLAG` on Linux in order to support passing
things correctly.
We can't expose `CMAKE_EXE_LINKER_FLAGS` to Swift, as it contains flags
that the Swift compiler doesn't recognize, but the other
language-specific variables are safe to expose.
