I don't know what else it could be but this works fine for me:

    cmake_minimum_required(VERSION 2.8.12)

    if(POLICY CMP0063)
         cmake_policy(SET CMP0063 NEW)
    endif()

    file(WRITE foo.cpp "int main() {}")

    set(CMAKE_CXX_VISIBILITY_PRESET hidden)

    add_executable(foo foo.cpp)


Is it possible that the scope where the policy warning comes from has 
its own cmake_minimum_required(VERSION) call? (e.g. is there more than one?)
