Not sure how this will work. The idea is to keep using -isystem for headers included from outside of webkit (like third party libraries) to avoid the noise produced by the warnings of some of this libraries (specially verbose with clang sometimes)...

But, I think I found a way of getting the list of default system include directories from GCC, so then I can append them to CMAKE_C/CXX_IMPLICIT_INCLUDE_DIRECTORIES. I will upload a patch soon if all the tests i'm doing with it end being successful.
