Documentation added by
* commit 4f4f2028b8 (Help: Add documentation for buildPresets and
testPresets, 2021-01-13, v3.20.0-rc1~51^2~7)
* commit 676ecf0d37 (cmake-presets: Add build and test presets,
2020-12-14, v3.20.0-rc1~51^2~6)
used square brackets in the `cmake --build` signature to indicate
non-optional alternatives, which is not a typical convention.
A common convention is to use parentheses instead, but in this
case it is probably clearer to list the two signatures separately.
Fixes: #22413
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Superseded by ``Tests/RunCMake/``.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.
