Actually, it's only failing on the Atomic class. I'm thinking it's
finding OpenThreads fine, but the configuration of Atomic between OSG
and VPB is somehow ending up different (the rest of OSG finds it, but
VPB doesn't for some reason).

Hi,
it seems that OpenThreads is not found while linking VPB. As a
workaround, you can try to specify that library in the linking options
of CMake.

I have use vs 2008 to compile OSG and VPB from latest SVN , everything is OK.
But When I use mingw gcc 3.4.4, OSG is OK, VPB has some link error. Many thanks!
