ENH: Add "if(POLICY policy-id)" option for IF command.
- This will help projects support multiple CMake versions.
- In order to set a policy when using a newer CMake but still
working with an older CMake one may write
if(POLICY CMP1234)
cmake_policy(SET CMP1234 NEW)
endif(POLICY CMP1234)
- Note that since CMake 2.4 does not have if(POLICY) supporting
it will also require using "if(COMMAND cmake_policy)"
