# 1) change the value of ossl_base below.
# 2) change the value of either 'libraries' or 'extra_link_args' depending on
#    your platform.
#    For OS X: use 'manual static link'

# statically link is a bit tricky
# Note: be sure to remove coro/ssl/openssl.c if you change this, see NPN probe below.
