#But for b2 build you need to create this file manually, just rename bz_version.h.in to bz_version.h
export BOOST_LIB_VISIBILITY="global" #possible values - global, protected, hidden.(https://www.boost.org/doc/libs/1_73_0/tools/build/doc/html/index.html#bbv2.builtin.features.visibility)
#The visibility should be set to global because boost_iostreams depends on symbols exported by bzip and if visibility is not set to global then all libs will be generated with hidden visiblity and boost_iostreams will fail in runtime saying not able to find "BZ2_bz..." symbol.
