P.P.S.  This is informative:

cmake --help-module FindBoost


eg:

FIND_PACKAGE(Boost 1.40 COMPONENTS filesystem system)
IF(Boost_FOUND)
    INCLUDE_DIRECTORIES(${Boost_INCLUDE_DIRS})
    LINK_DIRECTORIES(${Boost_LIBRARY_DIRS})

    ADD_EXECUTABLE(itkImageAffineCoregistration
itkImageAffineCoregistration.cxx)
    TARGET_LINK_LIBRARIES(itkImageAffineCoregistration ITKIO
ITKNumerics ${Boost_LIBRARIES})
ENDIF()
