# --prefix      prefix for the OpenSSL installation, which includes the
#               directories bin, lib, include, share/man, share/doc/openssl
#               This becomes the value of INSTALLTOP in Makefile

# --openssldir  OpenSSL data area, such as openssl.cnf, certificates and keys.
#               If it's a relative directory, it will be added on the directory
#               given with --prefix.
#               This becomes the value of OPENSSLDIR in Makefile and in C.

# --api         One of 0.9.8, 1.0.0 or 1.1.0.  Do not compile support for
#               interfaces deprecated as of the specified OpenSSL version.
#
36 37 38 39 40

# [no-]zlib     [don't] compile support for zlib compression.
