ExternalProject: Fix CMP0054 warning in _ep_parse_arguments 

Fix the CMP0054 warning:

 CMake Warning (dev) at .../Modules/ExternalProject.cmake:242 (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 keywords like "COMMAND" will no longer be interpreted as keywords
   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):
   .../Modules/ExternalProject.cmake:1938 (_ep_parse_arguments)
   CMakeLists.txt:5 (ExternalProject_Add)

by avoiding a reference to "${key}" or "COMMAND" in quotes.
