   Can you split what your CUDA toolset does into two separate steps:
   1. preprocessign the .cu file and constructing whatever C/C++ source 
are needed from it.
   2. running the C/C++ compiler on the generated files?

   In case your CUDA tool wants to run the compiler internally - I do 
not know of a way to do what you want without some heavy Boost Jam/Build 
modifications (which would generally start by duplicating the options 
you need for one compiler to get things working and then continue by 
removing the duplication but I sincerely hope this is not the case you 
need).

   On the other hand, if your CUDA tool simply prepares the needed C/C++ 
sources then everything should be pretty straight-forward. You just 
create a new TYPE for your .cu files, tell Boost Build how to generate 
source files from them and then let Boost Build do its magic from there. 
Once you do that you will be able to do things like:

   exe my-exe : aaa.cpp bbb.cu ;

   Which will make Boost Build transform your bbb.cu file into 
appropriate C/C++ sources, convert those sources to object files and 
then finally use those object files to link together your my-exe executable.

   There should be examples on how to construct such a new type in the 
docs (something about .VERBATIM files if I remember correctly). And feel 
free to send any questions to this list.

   Hope this helps.

   Best regards,
