Since commit 13c7bb5b0c (cmGeneratorExpression: Update strip function to
collect parsed expressions, 2025-04-08, v4.1.0-rc1~361^2~1), the logic
to strip generator expressions would error if the stripped expressions
were being collected and an expression without a `:` was found inside an
expression with a `:`. This resulted in an error when exporting a target
that contained such a generator expression in its link libraries or
compile definitions.
Address the error by checking whether the latest `$<` proceeded the
latest `:`.
CMake Tests Directory
*********************
This directory contains the CMake test suite.
See also the `CMake Testing Guide`_ and the `CMake Source Code Guide`_.
.. _`CMake Testing Guide`: ../Help/dev/testing.rst
.. _`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Superseded by ``Tests/RunCMake/``.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.
See `RunCMake/README.rst`_.
