Nothing is impossible ;-)

In the case of regex it's possible as long as all the generated
DLLs/SOs/LIBs have the name of the library in it: "boost_regex". So the same
applies to the signal library: "boost_signals". You just need to find out
what the mappings from the various build variants to the names, and use a
"stage" rule to create the needed versions. The regex library already has a
stage rule, for example, that generates a libboost_regex_debug.so, or
boost_regex_debug.dll.

So if you could tell us what the various names of the libraries that should
be generated I can probably give you a stage rule that will generate them.

Another alternative is to declare more targets (dll ...) with the specific
names and options.

Perhaps that might help. I guess the header would have the mappings from
compiler to name.
