cutil dll_mapping problem

For some reason, when I compile my code, the parts of cutil that are prefixed by DLL_MAPPING (i.e. cutFindFilePath()) give me:
error LNK2019: unresolved external symbol __imp__cutFindFilePath@8

but other portions of cutil are found fine.
Just wondering what I have/haven’t done to get that happening.
The matrixMulDrv example builds fine under VC++ 2005 Express, though I am using nvmex for compiling my code.
Thanks
