Hi Andreas,

It seems that the problem is caused by link options. After changing the 
link options from

-frounding-math -O3 -DNDEBUG --std=c++11 -lCGAL -lCGAL_ImageIO -lgmp

to

-frounding-math -O3 -DNDEBUG --std=c++11 -L/usr/local/lib -rdynamic 
/usr/local/lib/libmpfr.so /usr/local/lib/libgmp.so 
/usr/local/lib/libCGAL_ImageIO.so.11.0.1 
/usr/local/lib/libCGAL.so.11.0.1 /usr/local/lib/libboost_thread.so 
/usr/local/lib/libboost_system.so -lpthread -lGLU -lGL -lSM -lICE -lX11 
-lXext -lz /usr/local/lib/libCGAL_ImageIO.so.11.0.1 
/usr/local/lib/libCGAL.so.11.0.1 /usr/local/lib/libboost_thread.so 
/usr/local/lib/libboost_system.so -lpthread -lGLU -lGL -lSM -lICE -lX11 
-lXext -lz /usr/local/lib/libmpfr.so /usr/local/lib/libgmp.so 
/usr/local/lib/libboost_thread.so /usr/local/lib/libboost_system.so 
-lpthread -Wl,-rpath,/usr/local/lib

the code can work now.

I am not sure why both link options can be used to compile the code, but 
only the second one works when run the program. The second one is 
derived from the example makefile generated by Cmake.

Thanks,

Danyang
