    program options library for C++ (default version) 

libboost-thread-dev
    portable C++ multi-threading (default version) 

libgmp3-dev
    Multiprecision arithmetic library developers tools 

libmpfr-dev
    multiple precision floating-point computation developers tools 

libqt3-mt-dev

After you have installed libcgal-dev, if you want to compile it from sources, 
remove the packages libcgal and libcgal-dev from your system, and compile 
from 
CGAL sources. All the main dependencies of CGAL should remain installed.
