This property is implemented only when <LANG> is C or CXX.

Specify a semicolon-separated list containing a command line for the include-what-you-use 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>_INCLUDE_WHAT_YOU_USE variable if it is set when a target is created.
