Thanks for telling me the "auto-link" part. It works now.
Actually I did look at the FindBoost.cmake, but did not get a direct
answer for my case:

Here is my working case:

ADD_SUBDIRECTORY(src)
ADD_SUBDIRECTORY(example)
ADD_SUBDIRECTORY(python)
ADD_SUBDIRECTORY(test-suite)

In ./src, I find boost components except the unit_test_framework.

FIND_PACKAGE(Boost REQUIRED COMPONENTS regex program_options filesystem system)
IF(Boost_FOUND)
   add_definitions(${Boost_LIB_DIAGNOSTIC_DEFINITIONS})
   MESSAGE(STATUS "Boost: ${Boost_LIBRARIES}")
   INCLUDE_DIRECTORIES(${Boost_INCLUDE_DIRS})
ENDIF()

in ./test-suite, It is:

UNSET(Boost_LIBRARIES)
SET(Boost_USE_STATIC_LIBS OFF)
IF(UNIX)
   SET(Boost_USE_MULTITHREADED OFF)
ENDIF(UNIX)
find_package(Boost REQUIRED COMPONENTS unit_test_framework)
INCLUDE_DIRECTORIES(${Boost_INCLUDE_DIRS} ${GSL_INCLUDE_DIR})
# here is the unit-test executable
TARGET_LINK_LIBRARIES(utest tesla-static glps-static
${Boost_LIBRARIES} hdf5_hl hdf5 ${Boost_REGEX_LIBRARY} )
SET_TARGET_PROPERTIES(utest PROPERTIES COMPILE_FLAGS
"-DBOOST_TEST_DYN_LINK ${Boost_UNIT_TEST_FRAMEWORK_DYN_LINK}")
IF(WIN32)
   SET_TARGET_PROPERTIES(utest PROPERTIES COMPILE_FLAGS
       "-DBOOST_ALL_NO_LIB -DBOOST_TEST_DYN_LINK
${Boost_UNIT_TEST_FRAMEWORK_DYN_LINK}
${Boost_LIB_DIAGNOSTIC_DEFINITIONS}")
ENDIF(WIN32)


Thanks.
