Sure, that is a warning, does the build still work?

If so, you can do run cmake like this:

./cmake -Wno-dev

In the long run, this should be fixed in the SL CMake files.

Just add these statements at the top of the CMakeLists.txt for SL, and 
it should fix the problem for the whole project.

if(COMMAND cmake_policy)
       cmake_policy(SET CMP0003 NEW)
endif(COMMAND cmake_policy)


The only case that is not true is when there are more than one instance 
of  cmake_minimum_required(VERSION 2.4) in the project.  If so, you 
would need the above three lines after each cmake_minimum_required call.
