Hi there,

as I tryed to switch from 3.3.1 to 3.4 I found that I got some linker
errors in my application. Since I based the classes where the linker
errors happen on the CGAL example "Triangulation_2/adding_handles.cpp" I
tryed to compile the example only and I do get the same linker errors
(Debug-Configuration on Windows / Visual Studio 2008):

Error    1    error LNK2019: unresolved external symbol

Previously, I compiled and installed CGAL 3.4 with Visual studio 2008.

My Include-Dirs are:
$(CGALROOT)\include
$(CGALROOT)\auxiliary\gmp\include
$(BOOSTROOT)

And my Linker-Dirs are:
$(CGALROOT)\lib
$(CGALROOT)\auxiliary\gmp\lib
$(BOOSTROOT)\lib

CGALROOT is the CGAL 3.4 installation directory and BOOSTROOT ist the
Boost 1.37.0-Directory

Do you have any hints? Everything works with CGAL 3.3.1.

Thanks in advane,
regards,
Tom
