Specify a launcher for compile rules.


This property is intended for internal use by ctest(1). Projects and developers should use the <LANG>_COMPILER_LAUNCHER target properties or the associated CMAKE_<LANG>_COMPILER_LAUNCHER variables instead.

Makefile Generators and the Ninja generator prefix compiler commands with the given launcher command line. This is intended to allow launchers to intercept build problems with high granularity. Other generators ignore this property because their underlying build systems provide no hook to wrap individual commands with a launcher.
