It should not change.
Or in other words: It only changes if updating your
libraries would break your existing applications,
so the change was (really, really) needed.
Sorry, I am not sure if you are 100% comfortable with
how dynamic linking (on unix-like systems) work, so
I am unsure what your problem is.
(To make sure: I am not implying I am.)
You simply need the versions at runtime, they have
absolutely no relevance at compile time (because
when installing the libraries, a symbolic link is
added to make sure you link against the current
library version while having old version/versions
still installed). At compile time, you should
always link against "xyz.so" (or actually "xyz"
because the linker will add "so"), not ".so.99".
I am *guessing* that you actually want static
linking in your case.
