I am not an expert in Boost, but I do not believe there is such a script, or
even a pkg-config file. From the archives, the post
which is essentially identical to yours, received no replies. It seems most
people use either the GNU autotools or the CMake build system to automatically
find and use Boost headers and libraries. Of these, CMake is what I would
recommend, unless you plan to deploy or compile on obscure Unix platforms.
CMake provides the FindBoost.cmake, which in recent versions is quite decent.

Not that I can see. It is not so easy to do as it first appears, though.
Essentially, you would need to generate a pkg-config file containing the base
include for boost, the path to the library install dir and the names of all
the relevant libraries for the boost installation. However

that boost can or soon will be able to build with CMake.

These difficulties might be large enough that it is beyond the scope of pkg-
config or a utility script such as you describe. So perhaps simply using CMake
(or GNU autotools) would be the simplest solution. Such a solution would also
be able to automatically handle most or all or your configuration,
dependencies, and installation needs. Personally, I think that Makefiles are
only useful for small scripts or as an intermediate language.

Quite likely, though I think most people just goes with auto* or CMake.
Hope this helps.
