Description

We're using -std=c++11 in a few non-external project places as well as setting -fPIC. CMake provides the CMAKE_CXX_STANDARD flag (which we are also using) and the CMAKE_POSITION_INDEPENDENT_CODE flag for setting these options in a cross platform way (where it matters).

We should use these flags instead of using platform conditional checks to set their values explicitly.
