Mozilla builds with old libraries, IIRC they build on
something as ancient as RedHat 8.  To produce executables
that run with library version X or newer build with library
version X (assuming backward compatibility) -- to ensure
your program actually works with version X, you need to
build and test it with this version anyway (can be done for
instance on a virtual machine).  The other possibility is to
dlopen everything -- generally fragile. The third
possibility is to bundle the libraries -- probably not an
option with X.
