[Rivet] boost.m4 BOOST_FIND_LIB

[James Monk]

Hi everyone,

I'm trying to add reading of gzipped HepMC files to Rivet (together with the event filtering, I think this would improve the io performance enough that storing events becomes worthwhile).  For this, I need to link against libboost_iostreams.[so, dylib].  There's a m4 macro in boost.m4 of 

	BOOST_FIND_LIB([iostreams])

which you'd imagine would do the job, but seems to look for an empty filename.  There's not much documentation on that - does anyone know if/how it works?  Or an alternative neat way of finding a particular boost library?.. 

cheers,

James
