So, it appears that the installation didn't work after all...
The example stated above compiles just fine, but as soon as gmp is used, I
again receive many "undefined references errors". I tried to compile the
Triangulation_3/simple_triangulation_3.cpp and received these errors:

./debug\main.o: In function `ZN4CGAL8Gmpq_repC1Ev':

It is very frustrating that the gmp library keeps throwing errors, first
during configuration of CGAL, then during compilation of CGAL and now during
the compilation of a testprogram that uses CGAL.
I cannot believe, that this happens to everybody, who tries to use CGAL with
MinGW. So please, can someone describe every step of how you really compile
CGAL? Because, apparently I am doing something wrong. I already described my
steps and the resulting errors and slowly I am running out of ideas...
