# Build libzmq.a static library and libzmq.so dynamic library
#
# Usage: makelibzmq
#        BUILD_DLL=false makelibzmq     # Skip building DLL
#
# NOTE: We do a single compile run for both static and dynamic libraries
# which results in the static library having -Wc,exportall compiled objects;
# in practice this doesn't seem to cause a problem beyond using some extra
# space (around 10%).
