no argument specified with option option; ignoring switch
This warning occurs only when the /LIBPATH option is set. If no directory is specified with this option, then the linker ignores this option and generates this warning message.
If you do not need to override the existing environmental library settings, remove the /LIBPATH option from the linker command line. If you want to use an alternate search path for libraries, specify the alternate path following the /LIBPATH option. For example:
link /libpath:c:\foo\lib bar.obj
would direct the linker to search for the required libraries in c:\foo\lib before searching in the default locations.
