FindBoost-imported-targets
--------------------------
* The :module:`FindBoost` module now provides imported targets
such as ``Boost::boost`` and ``Boost::filesystem``.

# It is important to note that the imported targets behave differently

# different options (e.g. static or shared) will not override the

#
# % for version in /path/to/boost/sources/*
# do
# cmake -DBOOST_DIR=$version -P Utilities/Scripts/BoostScanDeps.cmake
# done
#
# The output was then updated by search and replace with these regexes:
#
# - Strip message(STATUS) prefix dashes
# s;^-- ;;
# - Indent
# s;^set(; set(;;
# - Add conditionals
# s;Scanning /path/to/boost/sources/boost_\(.*\)_\(.*\)_\(.*); elseif(NOT Boost_VERSION VERSION_LESS \10\20\3 AND Boost_VERSION VERSION_LESS xxxx);
#
# This results in the logic seen below, but will require the xxxx
# replacing with the following Boost release version (or the next
# minor version to be released, e.g. 1.59 was the latest at the time
# of writing, making 1.60 the next, so 106000 is the needed version
# number). Identical consecutive releases were then merged together
# by updating the end range of the first block and removing the
# following redundant blocks.
#
# Running the script against all historical releases should be
# required only if the BoostScanDeps.cmake script logic is changed.
# The addition of a new release should only require it to be run

# Scan the Boost headers and determine the library dependencies. Note

# inter-library dependencies. Library components for which this
# assumption does not hold true and which have dependencies on other
# Boost libraries will require special-casing. It also doesn't handle
# private dependencies not described in the headers, for static
# library dependencies--this is also a limitation of auto-linking, and
# I'm unaware of any specific instances where this would be
# problematic.

# Invoke in script mode, defining these variables:
# BOOST_DIR - the root of the boost includes
#
# The script will process each directory under the root as a
# "component". For each component, all the headers will be scanned to
# determine the components it depends upon by following all the
# possible includes from this component. This is to match the
# behaviour of autolinking.
