Fixed Decompress crash with 16bit TIFFs

Fixed Decompress crash with 16bit TIFFs by removing STATIC_DICOM_LIB from prefix header and including VTK and TIFF libs for Decompress target.

(I also wrote a mail to osirix-dev about this, with this patch, the problem is fixed and OsiriX works flawlessly again with non-Apple supported TIFFs)
