You are confusing the naming convention for shared libraries that are
intended to be linked into programs (or other libraries) at build time,
which normally have to be named libsomething.so because that is what
the compiler/linker flag -lsomething resolves to, with the naming
convention for shared libraries that are intended to be loaded at
run-time (sometimes called plug-ins), which require no particular
naming.
