# 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> |
