Update commit 1c15eb39d2 (Tests: Suppress failures on macOS arm64 due to
separate Xcode signing phase, 2021-02-22, v3.20.0-rc2~11^2) for Xcode 15,
which ignores our `-Xlinker -adhoc_codesign` flag, prioritizes its own
`-Xlinker -no_adhoc_codesign` flag, and does not add an ad-hoc signature
at link time.
Issue: #21845
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Superseded by ``Tests/RunCMake/``.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.
