No, the Ipopt/Matlab interface is not setup for use in Bonmin so far.

You could have a look at http://www.i2c2.aut.ac.nz/Wiki/OPTI
This brings an Bonmin/Matlab interface, but it is only for windows, I think.

The easiest is to build Bonmin with all dependencies in one round.
However, if you have an Ipopt installation in <IPOPTDIR>, you could try 
configure with  --with-coin-instdir=<IPOPTDIR> to let it pick Ipopt from 
there. Also setting the PKG_CONFIG_PATH environment variable so it 
includes IPOPTDIR/lib/pkgconfig (the directory with the ipopt.pc file) 
could work.
