Add https://www.gnu.org/software/autoconf-archive/ax_check_openssl.html to auto-detect compiler flags, linker flags and libraries to compile OpenSSL extensions. The M4 macro uses pkg-config and falls back to manual detection. Add autoconf magic to detect usable X509_VERIFY_PARAM_set1_host() and related functions. Refactor setup.py to use new config vars to compile _ssl and _hashlib modules. Signed-off-by: Christian Heimes <christian@python.org>

# SYNOPSIS
|
|
#
|
|
# AX_CHECK_OPENSSL([action-if-found[, action-if-not-found]])
|
|
#
|
|
# DESCRIPTION
|
|
#
|
|
# Look for OpenSSL in a number of default spots, or in a user-selected
|
|
# spot (via --with-openssl). Sets
|
|
#
|
|
# OPENSSL_INCLUDES to the include directives required
|
|
# OPENSSL_LIBS to the -l directives required
|
|
# OPENSSL_LDFLAGS to the -L or -R flags required
|
|
#
|
|
# and calls ACTION-IF-FOUND or ACTION-IF-NOT-FOUND appropriately
|
|
#
|
|
# This macro sets OPENSSL_INCLUDES such that source files should use the
|
|
# openssl/ directory in include directives:
|
|
#
|
|
# #include <openssl/hmac.h>
