Note that this creates a static convenience library which is not
portable to some architectures without extra compiler flags (need -fPIC
on amd64 and maybe other 64bit architectures).
Another way is to create a shared lib (and also install that one), but
don't provide headers for the library and don't give it a SOVERSION so
people won't link against it.
