I had to remove the
ADD_CUSTOM_COMMAND POST_BUILD section
in the (NOT MSVC_IDE) case from the OsgMacroUtils (line 345)
before I could build using nmake and cmake 2.6.1
I think this was needed in earlier versions of cmake,
the command copied and removed lib and exp files to the
bin dir, but now it will link with those files in the lib dir.
