Markus,

In order to build projects that build and link against GDAL/OGR it is
generally easiest to "install" GDAL.  This will copy the required include
files, DLLs and so forth into a seperate set of directories.  To configure
this modify the following variables in the gdal\nmake.opt file to your
liking ... the defaults are really just what I do on my machine and not
that great for general use:

BINDIR = D:\bin
PY_INST_DIR = D:\bin\pymod
LIBDIR = D:\bin\lib
INCDIR = D:\bin\include
DATADIR = D:\bin\data

Now when building a project your should include the INCDIR in your include
path, the LIBDIR in your libpath, and BINDIR in your path. All the include
files you need should be installed intot he INCDIR directory for instance.
The only library you should need to link against is gdal_i.lib, the stub
library for gdal11.dll.  Depending on your build options there may be
lots of other DLLs also required, but you will need to track that yourself.
For instance the DLLs for ECW, Oracle, OGDI, etc.

I hope this helps.  I have updated the GDAL building page in CVS to reflect
some of this information.

Best regards,
