Thank you for this.  I don't understand the answer as I don't see any code there
which will enable me to designate a location  e.g. boost_1_30_0/lib  where my
libraries could be.  An alternative would be to provide a link from e.g.
boost_1_30_0/lib to the location where the library actually is, down a very long
directory chain. Either would be nice as then I could do

g++  -I../boost_1_30_0 something.cpp -osomething -L../boost_1_30_0/lib -lsignals

from anywhere, and use a system of my choice e.g. Cmake, to control my own parts
of the software.  It is simple to include the noncompiled boost libraries in other
code, which is presumably the purpose of reusable library code.

I appreciate that bjam is there to automate the building of alternative
configurations of the libraries, and it works well for that.  Surely that doesn't
mean that users have to become experts in it to access the tutorial material on a
library?

Incidentally, the signals library is not included in the list of libraries which
have a compiled component, and there is no mention of the need for linking a
library in the otherwise excellent tutorial on the signals library.

Thanks again
