#
# SYNOPSIS
#
# AX_LIB_ORACLE_OCI([MINIMUM-VERSION])
#
# DESCRIPTION
#
# This macro provides tests of availability of Oracle OCI API of
# particular version or newer. This macros checks for Oracle OCI headers
# and libraries and defines compilation flags.
#
# Macro supports following options and their values:
#
# 1) Single-option usage:
#
# --with-oci -- path to ORACLE_HOME directory
#
# 2) Two-options usage (both options are required):
#
# --with-oci-include -- path to directory with OCI headers
# --with-oci-lib -- path to directory with OCI libraries
#
# NOTE: These options described above do not take yes|no values. If 'yes'
# value is passed, then WARNING message will be displayed, 'no' value, as
# well as the --without-oci-* variations will cause the macro to not check
# anything.
#
# This macro calls:
#
# AC_SUBST(ORACLE_OCI_CFLAGS)
# AC_SUBST(ORACLE_OCI_LDFLAGS)
# AC_SUBST(ORACLE_OCI_VERSION)
#
# And sets:
#
# HAVE_ORACLE_OCI
