[CMake] CMP0054 and CMake Modules

[thoni56]

I can't find a bug report on this. Is there one? 

Surely Cmake distributed modules should not generate this type of warnings.
Or am I misinterpreting the messages? 

I'm encountering numerous such problems/warnings in Cmake distributed
modules: 

CMake Warning (dev) at
/usr/share/cmake-3.3.1/Modules/CMakeParseImplicitLinkInfo.cmake:58 (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 "" will no longer be dereferenced when the policy is 
  set to NEW.  Since the policy is not set the OLD behavior will be used.
