Fix CGAL build with ICPC

The original code was adding "-fp-model strict" to all targets
Regardless of the language which led to compilation issues with CMake
Project that contained CUDA or C code (untesed with C).

Change fp-model strict to fp-model=strict for more compatibility with
Wrappers like nvcc.
