Hi

I'm encountering link problem when I try to compile the hello world example  with CGAL 3.9, boost 1.47, qt4.8,and VS2010 on Win7 64bit

the error messge is:

1>main.obj : error LNK2019: unresolved external symbol __imp____gmpz_clear referenced in function "public: __thiscall CORE::BigIntRep::~BigIntRep(void)" (??1BigIntRep@CORE@@QAE@XZ)

It seems the Gmp is not linked properly. After refer several similar discusses, such as [1] and [2]  

I try to use two Preprocessor definition, CGAL_NO_AUTOLINK_MPFR  and CGAL_NO_AUTOLINK_GMP, to avoid the lack gmp-vc100-mt-gd.lib error

However, the VS2010 still cannot link Gmp properly.

My VS2010 project setting and error message are listed below, my platform is win7 64bit, and the attached file is the log of CMake 

Anyone know how to solve this problem ? 

Thank for your time and help.
