Simulink library linking error

Hi all,
I have the following situation:
1) I have a sfunction builder block, where I have defined a function in C, which uses external library (libxml2 to be precise). I use visual studio 2010 to compile the sfunction.
2) I am able to build the sfunction, and when I simulate/run on computer, the system responds the way I want it.
3) Trying to build the model though creates an error.
To be precise, the error I get on matlab command prompt is:
LINKING APPLICATION ...
< lnkppc >
(E) #A0368-D Unresolved external:
xmlParseDoc (first referenced in module: parse.o50)
xmlCharStrdup (first referenced in module: parse.o50)
xmlDocGetRootElement (first referenced in module: parse.o50)
Errors: 1, Warnings: 0
-- call "C:\SW\dSPACE RCPHIL 7.4\Compiler\PPCTools37\BIN\lnkppc.exe" -K0 -QmsA0314 -QmeA0307 -QmeA0329 -m..\test_parser.map -o ..\test_parser.ppc -c _tmp_test_parser.lk
LINKING FAILED (1)
MAKE PROCESS ABORTED
Any help would be deeply appreciated! Thanks in advance!

In case anybody experiences the same problem as me:
What I did was to change the used library. Because I deploy he project on a platform which does not support win32 libraries, I had to include the source files of the library.
Also, in the Code Generation: I set as make command:
make_rti LNK_OPTS="-QmsA0314"
At last, do not forget to include all the libraries and any source files in: Code Generation/Custom Code/
These were enough to get my project running (although a major overhaul).
