[osg-submissions] Using command-line build system nmake to build OpenSceneGraph does not work

[René Molenaar]

The idea of the OSG_MSVC_VERSIONED_DLL hack is this;
* the dll are versioned by prefixing the name with
osg${OPENSCENEGRAPH_SOVERSION}-
* the dll's are placed in the binary folder

The result is that you can skip install to run application, just go to the
bin folder, the dll's and plugins can now be found (because they are there).
The versioning is to prevent or reduce 'dll hell' see
http://en.wikipedia.org/wiki/Dll_hell

This hack broke the power of cmake: "CMake generates native makefiles and
workspaces that can be used in the compiler environment of your choice." If
your choice happens to be nmake (not very obvious one I guess...)  the
makefiles will  have an error.

These files make it possible to use nmake again (it always worked fine),
with the OSG_MSVC_VERSIONED_DLL results.

Hope that answers your question.
