# This module builds Boost. It sets the following variables:
#
#  Boost_FOUND : boolean            - system has Boost
#  BOOST_ROOT : path
#  Boost_LIBRARIES : list(filepath) - the libraries needed to use Boost
#  Boost_LIBRARY_DIR_RELEASE : path - the library path
#  Boost_INCLUDE_DIRS : list(path)  - the Boost include directories
#
# Following hints are respected
#
#  Boost_USE_STATIC_LIBS : boolean (default: OFF)
#  Boost_USE_MULTITHREADED : boolean (default: OFF)
#  BOOST_J: integer (defanult 1)
