To compile anything using CGAL in 64 bits, you need to have Boost libraries 
compiled in 64 bits mode. You also need gmp and mpfr libraries in 64 bits. 
Then you need to recompile CGAL libraries in 64 bits mode too.

I advise you to:
  - download Boost sources and compile them in 64 bits,
  - install a second copy of CGAL in C:\Program Files\CGAL-3.8 (instead of C:
\Program Files (x86)\CGAL-3.8), and choose 64 bits versions of third-party 
precompiled libraries.
