I am trying to find out which path actually resolves to %{_includedir} in a Centos6 installation. I understand that this is normally "/usr/include" but where can I find where it is actually set or somehow "echo" it? Basically, a spec I am using has "%dir %{_includedir}/someFolder/someFile". Everything runs fine but I can't find "/usr/include/someFolder". I assume it has been created somewhere else and I am trying to find out where that is.
