There are other flags, such as several -I.

My guess is that you are using the Intel compiler with the the 
<CGAL/compiler_config.h> that was generated during the compilation of CGAL 
libraries with g++. Please rebuild your CGAL libraries with that the Intel 
Compiler. icpc version 12.1 should be supported. It is in the set of tested 
compilers in the CGAL daily tests suite.
