If you compile Boost using default bjam settings, only two variables
have to be specified: BOOST_ROOT and Boost_USE_STATIC_LIBS. When using
static libraries, setting

option(Boost_USE_STATIC_LIBS "Use static Boost libraries" ON)

should be sufficient. Also, you might want to set the
Boost_ADDITIONAL_VERSIONS variable to "1.46.1", since 1.46 is the last
version known to FindBoost.cmake when using cmake 2.8.4.
