This test runs the `Tests/QtAutogen/MocInclude` test inside symlinked
directories. The `MocInclude` test previously relied on
`get_filename_component(... REALPATH)` to get the real source tree
location and compute the path to `AutogenCoreTest.cmake` from it.
However, this does not work on Windows due to issue #17206. The
test has been passing on Windows only on machines where symlinks
cannot be created and the main part of the test is skipped. On
machines where symlinks can be created, the test failed with that
approach. Fix it by explicitly passing the path to the helper
script in as a cache entry. Avoid relying on `REALPATH`.
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Superseded by ``Tests/RunCMake/``.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.
