The feature needs a specialized implementation to place headers
in the right place inside frameworks. To avoid silently doing
the wrong thing, make this case an error for the 3.23 series.
Issue: #23386
Redefine the `CMAKE_CI_PACKAGE` pipeline schedule variable to
indicate whether it is for a development version (`dev`) or a
release version (`v[0-9]...`). Use this to automatically turn
package upload jobs on or off without having to edit the jobs
in `.gitlab-ci.yml` for release branches.
The language-specific variable references the general one already,
but the general one did not mention the language-specific one.
Add that cross reference to improve discoverability.
CMake only sets `CMAKE_CACHEFILE_DIR` when writing `CMakeCache.txt`,
so the variable will usually be undefined when `CMakeLists.txt` runs.
Revise its documentation to clarify that `CMAKE_BINARY_DIR` should
be used instead.
05e510bf0b CMP0132: Don't set compiler environment variables on first run

When running CMake for the first time in a build tree, for some
generators CMake would set compiler environment variables
like CC, CXX, etc. when the corresponding language is enabled.
That behavior was never documented and can result in different
behavior between the first and subsequent runs. Add a policy
to no longer set those environment variables.
Fixes: #21378
Variable CMAKE_LINK_(LIBRARY|GROUP)_USING_<FEATURE>_SUPPORTED is evaluated
only if CMAKE_<LANG>_LINK_(LIBRARY|GROUP)_USING_<FEATURE>_SUPPORTED is not defined.
This new behavior enable to activate a feature globally on a platform and to disable
it for some compilers and languages.
Previously we always used content guarded by `$<LINK_ONLY:...>`
in `LINK_LIBRARIES`, even when evaluating for non-linking usage
requirements. Add a policy to honor `LINK_ONLY` in `LINK_LIBRARIES`
the same way we already do in `INTERFACE_LINK_LIBRARIES`.
Similar to GNU tar add a --touch option to the tar extract command to
skip extracting the timestamps from the files in the archive
effectively touching them as if they were just created.
Issue: #22746
Remove the requirement that the variable name have a prefix while
keeping the suffix requirement. Require that the property name
contains an underscore. Update docs and tests accordingly.
Fixes: #23340
In commit f3ad061858 (Add usage requirements to update direct link
dependencies, 2022-01-12, v3.23.0-rc1~44^2), we evaluated the transitive
closure of `INTERFACE_LINK_LIBRARIES` as a non-linking usage requirement.
That left out `INTERFACE_LINK_LIBRARIES_DIRECT` link dependencies that
appear behind private dependencies of a static library, guarded by the
`$<LINK_ONLY:...>` generator expression. At the time, that decision was
intentional, in order to prevent arbitrary usage requirements from
leaking out of `PRIVATE` dependencies.
Since then, we've revised evaluation of `LINK_LIBRARIES` to distinguish
between collecting link dependencies and other usage requirements. Use
that information when following `INTERFACE_LINK_LIBRARIES` to collect
the matching kind of requirements from `INTERFACE_LINK_LIBRARIES_DIRECT`.
Fixes: #22496
