Linker error while compiling on Mac OS X

[adambudziak]

When running with make in the root dir the linker returns the following error:

c++ -o lib/libmclbn384_256.dylib obj/bn_c384_256.o -shared -L/usr/local/opt/openssl/lib -L/usr/local/opt/gmp/lib -lgmp -lgmpxx -lcrypto -m64  -lmcl -L./lib

The error shows that bn_c384_256.o is built with MCL_USE_GMP=0, so could you try make clean and make?

Och, I feel so dumb. Cleaning works (I tried cleaning inside build dir for CMake and it didn't work.) Thx.
