This directory contains the CMake test suite. See also the CMake Source Code Guide.

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 Superseded by Tests/RunCMake/.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.
