30# This becomes the value of INSTALLTOP in Makefile
31# (Default: /usr/local)

37#
38# --cross-compile-prefix Add specified prefix to binutils components.

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

43# no-hw-xxx do not compile support for specific crypto hardware.
44# Generic OpenSSL-style methods relating to this support
45# are always compiled but return NULL if the hardware
46# support isn't compiled.
47# no-hw do not compile support for any crypto hardware.
48# [no-]threads [don't] try to create a library that is suitable for
49# multithreaded applications (default is "threads" if we
50# know how to do it)
51# [no-]shared [don't] try to create shared libraries when supported.
52# [no-]pic [don't] try to build position independent code when supported.
53# If disabled, it also disables shared and dynamic-engine.
54# no-asm do not use assembler
55# no-dso do not compile in any native shared-library methods. This
56# will ensure that all methods just return NULL.
57# no-egd do not compile support for the entropy-gathering daemon APIs
58# [no-]zlib [don't] compile support for zlib compression.
59# zlib-dynamic Like "zlib", but the zlib library is expected to be a shared
60# library and will be loaded in run-time by the OpenSSL library.

64# Enable weak ciphers that are disabled by default. This currently
