You are trying to link a shared library (libCGALcore.dylib) with a static one 
(/usr/local/libgmp.a). That is not possible (for PIC¹ reasons).

¹) PIC: position independant code. A shared library needs its code to be 
relocatable (PIC), where a static library usually contain non-PIC code.

You need to recompile you GMP library into a shared library. Use the 
flag "--enable-shared" in the "./configure" command line.
