How about 'changing destructor into virtual' to the class?
I think we don't need to recompile all library if we only add a
constructor to the class or add a data member to the library.
You should recompile them
Your build system (which is off-topic) should recompile them for you, based
on dependency analysis. If you don't have a build system, get one before
doing anything else. C++ doesn't work without a Makefile or something to
manage these dependencies for you.
but see this article on reducing
compile-time dependencies:
http://www.gotw.ca/publications/mill04.htm
Then read /Large Scale C++ Software Design/ by John Lakos, no matter what
the size of your project.
