Hmm. That should have worked since the FindBoost.cmake evaluates the
environment variable BOOST_ROOT or BOOSTROOT

 # If BOOST_ROOT was defined in the environment, use it.
  if (NOT BOOST_ROOT AND NOT $ENV{BOOST_ROOT} STREQUAL "")
    set(BOOST_ROOT $ENV{BOOST_ROOT})
  endif()

  # If BOOSTROOT was defined in the environment, use it.
  if (NOT BOOST_ROOT AND NOT $ENV{BOOSTROOT} STREQUAL "")
    set(BOOST_ROOT $ENV{BOOSTROOT})
  endif()

I will try to figure this one out..
