Continue b665966933 (cmComputeLinkInformation: track OBJECT library
dependencies, 2023-07-22) which added explicitly listed `OBJECT`
libraries to the list of targets which the collator needs to consider.
Now also consider targets which provide objects directly to the target
via a `$<TARGET_OBJECT>` source lists.
Also add tests which use target objects directly and through an
`INTERFACE` library with target objects in its own sources.
Fixes: #25365
CMake Tests Directory
*********************
This directory contains the CMake test suite.
See also the `CMake Source Code Guide`_.
.. _`CMake Source Code Guide`: ../Help/dev/source.rst
Many tests exist as immediate subdirectories, but some tests
are organized as follows.
* ``CMakeLib/``:
Source code, used for tests, that links to the ``CMakeLib`` library
defined over in ``Source/``.
* ``CMakeOnly/``:
Deprecated. Tests that run CMake to generate a project but not build it.
Superseded by ``Tests/RunCMake/``.
* ``Find*/``:
Tests for specific find modules that can only be run on machines with
the corresponding packages installed. They are enabled in
``CMakeLists.txt`` by undocumented options used on CI builds.
* ``Module/``:
Tests for specific CMake modules.
* ``RunCMake/``:
Tests that run CMake and/or other tools while precisely checking
their return code and stdout/stderr content. Useful for testing
error cases and diagnostic output.
