The boost macros at the autoconf library are pretty good if you're using 
autoconf: http://autoconf-archive.cryp.to/.

I had to add one case to AX_BOOST_FILESYSTEM to cope with 1.34 in the 
line that starts "for ax_lib in... ", so I expect that will be true for 
the other libraries too, but at least it has the logic to look for 
something that works!
