Subject: [PATCH] override CPPFLAGS, CXXFLAGS and CFLAGS in Makefile
When CPPFLAGS is passed on the command line, include paths for the
bundled libraries are lost. Since the hand written Makefile want
to use them unconditionally, we need to use the key word "override"
before CPPFLAGS.
Do the same for CXXFLAGS and CFLAGS otherwise -fPIC is lost.
