It would be best if the autoconf changes is based on pkgconfig as shown
in
https://github.com/gluster/glusterfs/blob/master/api/examples/configure.ac.
If you do not want to introduce pkgconfig dependency (if you already do
not have it) then it would be good to adopt the steps mentioned in
section "2." of
https://github.com/gluster/glusterfs/blob/master/api/examples/README.
That would basically mean including "-I/path/include/glusterfs" in
CPPFLAGS and only "#include <api/glfs.h>" instead of <glusterfs/api/glfs.h>.
