Thanks, I see! Now I'm trying to understand how to link to prebuilt
libraries (if no Jamfiles are around). In order to keep a project's
Jamfiles platform-independent I defined the following targets in

lib boost_date_time : : <name>libboost_date_time-vc90-mt <search>C:/lib :
: <include>C:/include ;
lib boost_filesystem : : <name>libboost_filesystem-vc90-mt <search>C:/lib
: : <include>C:/include ;

How do I reference now these targets in my project's Jamfiles? If I simply
add boost_date_time to the sources of an exe rule bjam complains about not
finding a file or target with this name.

I also wonder if I can group the libraries somehow. If all my Boost C++
libraries can be found in C:\lib and all header files are in C:\include it
should be possible to use an alias? I tried this:

alias boost-dirs : : <search>C:/lib : : <include>C:/include ;
lib boost_date_time : boost-dirs : <name>libboost_date_time-vc90-mt ;
lib boost_filesystem : boost-dirs : <name>libboost_filesystem-vc90-mt ;

While the include directory is passed through the search directory isn't
used (compiling works but linking fails). Where do I have to put <search>?
Or do I have to use another feature?
