    CMake: Silence CMP0054 warning with separate project, enable_language calls.
    
    This addresses the warning:
    
      -- The CXX compiler identification is MSVC 18.0.31101.0
      CMake Warning (dev) at C:/Program Files (x86)/CMake/share/cmake-3.3/Modules/CMakeDetermineCXXCompiler.cmake:106 (if):
        Policy CMP0054 is not set: Only interpret if() arguments as variables or
        keywords when unquoted.  Run "cmake --help-policy CMP0054" for policy
        details.  Use the cmake_policy command to set the policy and suppress this
        warning.
    
        Quoted variables like "MSVC" will no longer be dereferenced when the policy
        is set to NEW.  Since the policy is not set the OLD behavior will be used.
      Call Stack (most recent call first):
        CMakeLists.txt:23 (enable_language)
    
    That occurs with MSVC / Ninja with the following CMakeLists.txt:
    
      cmake_minimum_required(VERSION 2.8.9 FATAL_ERROR)
      project(MyProj NONE)
      enable_language(C)
      enable_language(CXX)
