-# Deprecated. For Boost Python, use :command:`SEARCH_FOR_BOOST_PYTHON`. For
-# other Boost components, use::
-#
-# add_project_dependency(Boost COMPONENTS ...) # or other argument to the
-# find_package command.
-#
-# or, if you don't want it to be exported::
-#
-# find_package(Boost COMPONENTS ...) # or other argument to the find_package
-# command.
-#
-# This macro deals with Visual Studio Fortran incompatibilities and add detected
-# flags to the pkg-config file automatically.
-#
-# The components to be detected is controlled by :variable:`BOOST_COMPONENTS`.
-#
-# A special treatment must be done for the boost-python component. For boost >=
-# 1.67.0, FindPython macro should be called first in order to automatically
-# detect the right boost-python component version according to the Python
-# version (2.7 or 3.x).
