The messages you see are from the link step of the compilation.  Once
you have the appropriate include files, each source file can be compiled
into an object file.  After all source files are compiled, the object
files must be linked together to form the final executable.  Part of
that step involves linking to libraries of object files corresponding to
the functions that your header included.  The errors you see are from
the attempt to find the object code associated with the particular
function names that are cited. The problem is, the library of object
files associated with CGL are not being found by your compiler.

What you need to do is, first, build the CGL library, and second, make
sure the library is available to MSVS during the build of the uflOSI
executable.

Unfortunately, I don't have experience building this in MSVS.  But if
you find out about building with libraries in MSVS, I think it should be
straightforward.  Post again if you still have problems.  Somebody
should be able to help.
