Yes, the problem is that I do not explicitly set BOOST_ROOT.

I did notice in the FindBoost that there is a subtle difference in how the

Interesting; I used the BoostPro installer so it is indeed all underscores
(boost_1_38).

Do you actually have the Dynamic multi-threaded boost libs installed?

Yep, I have all types (single threaded vs. multi-threaded, static vs.
shared) installed.

Thanks, I didn't know about Boost_THREAD_LIBRARY_DEBUG. That helps me
eliminate a little bit of code.

Anyway, Arnaud Gelas and I took a look at FindBoost.cmake, and discovered
the problem. FIND_PATH is called to populate Boost_INCLUDE_DIR, but not
until line 478 (CMake 2.6-patch4), whereas the components are checked before
that (e.g., around line 303 there is an "IF(Boost_INCLUDE_DIR)" block that
never executes).

Andreas, shouldn't FIND_PATH be called right away, and once the
Boost_INCLUDE_DIR is known, then subsequently check for individual
components of Boost?
