# <LANG>_INCLUDE_WHAT_YOU_USE

Added in version 3.3.

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.

Added in version 3.27: This property supports `generator expressions`.

Added in version 3.27: `SKIP_LINTING` can be set on individual source files to exclude them from the linting tools defined by `<LANG>_CPPLINT`, `<LANG>_CLANG_TIDY`, `<LANG>_CPPCHECK`, and `<LANG>_INCLUDE_WHAT_YOU_USE`. When `SKIP_LINTING` is set to true on a source file, those tools will not be run on that specific file.
