Lib1Sources = [ some-glob-rule-here... ] ;
Lib2Sources = [ some-glob-rule-here... ] ;

exe Exe1 : $(Lib1Sources) $(Lib2Sources) Exe1/Exe1Main.cpp ;

...
some-glob-rule-here, possibly something like:

[ GLOB *.cpp : Library1/Library1Project1 ]

It's the glob rule that's the tricky part in your situation. But there is
nothing in Boost.Build from including sources from anywhere in your targets.

But I have a question... why isn't a static lib(archive) suitable? It should
not have any problems with static inits for C++... Or at least it works for
me with GCC.
