This always happens. Declare complete stumpitude and almost immediately
find a solution. This is the problem: I'm linking statically and
boost_thread wants to link dynamically.

The clue is in the first error in the build log: "undefined reference
to `_imp___blablabla'". The "_imp___" part gives it away. The fix is to
define BOOST_THREAD_USE_LIB in your CMakeLists.txt:

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -DBOOST_THREAD_USE_LIB=1")

I haven't tested it, but it builds without complaint now.
