New in version 3.6.
This property is implemented only when <LANG> is C or CXX.
Specify a semicolon-separated list containing a command line for the clang-tidy tool. The Makefile Generators and the Ninja generator will run this tool along with the compiler and report a warning if the tool reports any problems.
This property is initialized by the value of the CMAKE_<LANG>_CLANG_TIDY variable if it is set when a target is created.
