first off I believe the fact that it prints the right versions is likely
a red herring, I don't think cmake 2.6.4 has support for boost 1.39,
i.e. it is not on the list of versions it looks for and I suspect that
causes some silly test to fail.
Can you try extending that list by adding a new variable (case
sensitive) in the gui:
Boost_ADDITIONAL_VERSIONS and set its value to "1.39.0 1.39" (without
the "").
With that it should suffice to set
BOOST_ROOT to "D:/Development/support/dist/boost" and
BOOST_LIBRARYDIR to "D:/Development/support/dist/boost/stage32/lib"
or stage64 depending for which arch you are building (you need
BOOST_LIBRARYDIR because of the custom named stage directories)

hm, we don't have a user switch for that and I've never tried it, but it
might be enough to go to the Dependencies section in OpenSG's
CMakeLists.txt and change SET(Boost_USE_STATIC_LIBS OFF) to ON (around
line 232).

normally setting the variables manually (although tedious) gets the job
done, I really suspect the problem is that boost 1.39 was released only
3 days before cmake 2.6.4 and it lacks support.

I'd much rather see FindBoost.cmake improved, as part of the reason to
switch to cmake (at least for me) was not having to deal with the
complexity of picking up the right boost libs.
Cheers,
Carsten
