Neal,

What you have there should be being added to the linker flags for
*executables*.  It at least works fine on my system with 2.6.2 (Linux).  It
will not work for libraries, however, so you probably want something better.

In this light I suggest you try using FindBoost.cmake.  I believe the
version in 2.6.2 should work for your needs although if you have any issues
at all please try[1] CMake 2.6.3 RC 11 and see the updated FindBoost
documentation for debugging options.

find_package(Boost <minimum_version> REQUIRED regex)
include_directories(${Boost_INCLUDE_DIRS})
add_executable(foo foo.cc)
target_link_libraries(foo ${Boost_LIBRARIES})
