New in version 3.26.

This property is implemented only when <LANG> is C, CXX, OBJC or OBJCXX, and only has an effect when <LANG>_CLANG_TIDY is set.

Specify a directory for the clang-tidy tool to put .yaml files containing its suggested changes in. This can be used for automated mass refactoring by clang-tidy. Each object file that gets compiled will have a corresponding .yaml file in this directory. After the build is completed, you can run clang-apply-replacements on this directory to simultaneously apply all suggested changes to the code base. If this property is not an absolute directory, it is assumed to be relative to the target's binary directory. This property should be preferred over adding an --export-fixes or --fix argument directly to the <LANG>_CLANG_TIDY property.

When this property is set, CMake takes ownership of the specified directory, and may create, modify, or delete files and directories within the directory at any time during configure or build time. Users should use a dedicated directory for exporting clang-tidy fixes to avoid having files deleted or overwritten by CMake. Users should not create, modify, or delete files in this directory.

This property is initialized by the value of the CMAKE_<LANG>_CLANG_TIDY_EXPORT_FIXES_DIR variable if it is set when a target is created.
