Thanks again for the advice! Yes, in the first place it was like this, 
but after Andy told me that it should be in the if-block it is moved 
after find_package. The full code now is here: 
http://nopaste.info/9e73e7d3ac.html

But after that, I googled if there is any hint what I could be doing 
wrong linking boost log. I found the following thread: 
http://stackoverflow.com/questions/16540171/boost-log-gcc-4-4-and-cmake 
It basiacally says that one has to add multiple libraries to get boost 
log running and that one has to get them in a certain order. After 
addding them (so now find_package uses find_package( Boost 1.55.0 
COMPONENTS system thread filesystem date_time log log_setup REQUIRED) 
and the code like in http://nopaste.info/65b3273ade.html) I got the errors:

CMakeFiles\Hasselbrack.dir/objects.a(main.cpp.obj):main.cpp:(.text+0x285): 
undefined reference to `std::ios_base::Init::~Init()'
CMakeFiles\Hasselbrack.dir/objects.a(main.cpp.obj):main.cpp:(.text+0x2a6): 
undefined reference to `std::ios_base::Init::Init()'
c:/mingw/bin/../lib/gcc/mingw32/4.7.2/../../../../mingw32/bin/ld.exe:

c:/mingw/bin/../lib/gcc/mingw32/4.7.2/../../../../mingw32/bin/ld.exe: 
final link failed: Invalid operation
collect2.exe: Fehler: ld gab 1 als Ende-Status zurück

So something still does not work with the linker... Do you have any idea 
what?
