Make sure your cmake portgroup is up to date; there were some recent problematic changes that were fixed a couple days later. With the current revision, it adds the value of cppflags to cflags and cxxflags at pre-configure time if it is not empty. So you can change or clear cppflags prior to pre-configure time if you wish, but there’s no need to remove values from cflags and cxxflags that they don’t contain to begin with.
