# WARNING: When doing this from fresh boost sources, note that in the file
# /boost/config/user.hpp the BOOST_ALL_NO_LIB define has been uncommented.
# Otherwise, we will get linker errors on MSVC because of boost auto-linking. If
# you don't care about Windows then feel free to use the raw boost version of
# /boost/config/user.hpp
