<LANG>_COMPILER_LAUNCHER

.. versionadded:: 3.4

This property is implemented only when <LANG> is C, CXX, Fortran, HIP, ISPC, OBJC, OBJCXX, or CUDA.

Specify a :ref:semicolon-separated list <CMake Language Lists> containing a command line for a compiler launching tool. The :ref:Makefile Generators and the :generator:Ninja generator will run this tool and pass the compiler and its arguments to the tool. Some example tools are distcc and ccache.

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

.. versionadded:: 3.25

The property value may use :manual:generator expressions <cmake-generator-expressions(7)>.
