#
# 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>
