Then I'm back to my original question: Can I use boost with my
application if cppcms uses another version of boost internally? From
what you have said "It is quite easy to show how programs using
different versions of boost::regex in same code base crash." I get
that *NO* I can't. But in the same time you say that cppcms should not
be compiled against an external boost so how could I use boost
together with cppcms in my application?
