  7 +# AX_CHECK_OPENSSL([action-if-found[, action-if-not-found]])
  8 +#
  9 +# DESCRIPTION
  10 +#
  11 +# Look for OpenSSL in a number of default spots, or in a user-selected
  12 +# spot (via --with-openssl). Sets
  13 +#
  14 +# OPENSSL_INCLUDES to the include directives required
  15 +# OPENSSL_LIBS to the -l directives required
  16 +# OPENSSL_LDFLAGS to the -L or -R flags required
  17 +#
  18 +# and calls ACTION-IF-FOUND or ACTION-IF-NOT-FOUND appropriately
  19 +#
  20 +# This macro sets OPENSSL_INCLUDES such that source files should use the
  21 +# openssl/ directory in include directives:
  22 +#
  23 +# #include <openssl/hmac.h>
