Why do I need a * .obj file with static binding?

I am not sure why this is so. I am distributing static * .lib to several projects, but this static lib generates many * .obj files. It looks like I need to distribute * .obj files with * .lib as well. Otherwise, I get this error:

1>LINK : fatal error LNK1181: cannot open input file 'nsglCore.obj'

Why is this? Is there a way to include data in * .obj files in * .lib? Maybe a switch in the compiler?

This is my configuration for a static library:

C / C ++

/Od /GT /D "WIN32" /D "NDEBUG" /D "_LIB" /D "_WINDOWS" /D "_UNICODE" /D "UNICODE" /Gm /EHsc /MD /Yu"stdafx.hpp" /Fp"e:\Development\Projects\nsGameLib\Source\Core\Intermediate\nsglCore-Win32-Release.pch" /Fo"e:\Development\Projects\nsGameLib\Source\Core\Intermediate\\" /Fd"e:\Development\Projects\nsGameLib\Source\Core\Intermediate\vc90-Release.pdb" /W3 /nologo /c /Zi /TP /errorReport:prompt

This is my configuration for a project using a static library:

: Dependancy Library - No

This is a Visual Studio option to capture .obj files directly, not a .lib file. I assume this is necessary to avoid the link step and thus speed up compilation.

In general, you should install a project that creates the lib file as a function of the project that uses it (under the general properties in this properties window). Then you include the library library dependencies. In most cases, this works well.
