I can fix this in CVS, but might have a slightly better way. Can you tell
me what the value of CMAKE_CXX_COMPILER_ID is on Intel C++?

This is the second time today I've heard of people placing import libraries
in bin folders. Any reason why this is happening?

You could look into the Boost preprocessor definitions that disable auto
linking and rely instead on CMake's target_link_libraries(). See the
FindBoost docs for more information.
