It is not the best way. There are two types of libraries: static and 
shared. For gmp you can build both (see the configure options). Linking 
with a shared library (lib*.so) means adding a runtime dependancy on this 
library. Linking with a static library or archive (lib*.a) means including 
relevant portions of this library in the object that is produced. To make 
it simple, only link the executable file with the static libraries. Here 
you are building a shared object so you should not link with a static 
library, you can either not link with gmp at all (and remember to link 
with gmp when you create an executable file using this shared object) or 
link with a shared version of libgmp.
