That's because it is a header-only library. It is either hard (and non-
portable) or impossible to do dynamic dispatch in a header-only library,
depending on the compiler and compiler version. (At least in past GCC
versions, it was impossible. This may or may not have improved since.)
Hence, dynamic dispatch, if desired, is left to the client application. And
I agree that this makes the library mostly useless.
You need an actual shared object with actual functions to do dynamic
dispatch nicely and transparently.
