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.
