-I is not CFLAGS but CPPFLAGS.

That's simply gtk prefering windows style development. If they made it
proper part of the headers to #include there would be no problem and it
would even work with different plugins of some program using different
versions.
Gtk simply is not a good example for any sane library handling, as it
insists of inventing it's own way for everything. (Just think of the
inlining of other libraries' functions so one never can know that
libraries are actually used).
