    Add options to launch the compiler through tools like ccache or distcc · 698f7597

    Create a <LANG>_COMPILER_LAUNCHER target property (initialized by a
    CMAKE_<LANG>_COMPILER_LAUNCHER variable) to specify a compiler launcher
    tool.  This will supersede the CMAKE_<LANG>_COMPILER_ARG1 approach to
    using such tools.  The old approach set CMAKE_<LANG>_COMPILER to the
    launcher tool while the new approach leaves this variable set to the
    actual compiler.
    Implement this property for Makefile and Ninja generators.  It cannot be
    implemented for VS or Xcode generators as the IDE build tools offer no
    such hooks.
