Do you mean the build should use its own in-tree copy of libftdipp.pc
to set -I flags when building libftdi itself?
libftdipp.pc.in would have to be modified to include -I flags for
boost, but I can't think of a great way to have autoconf use
pkg-config to look for the in-tree .pc file at the moment. Is there a
simple autoconf-ish way to do that? Seems much easier to just include
BOOST_CPPFLAGS in Makefile.am.
Modifying libftdipp.pc.in to include -I /path/to/boost/include
certainly seems reasonable for consumers of libftdi that might include
ftdi.hpp (which currently requires boost).
