# SYNOPSIS
#
#   AX_OPEN62541_CHECK_LIB([STATIC-FIRST = `no'], [ACTION-IF-FOUND],
#                          [ACTION-IF-NOT-FOUND])
#
# DESCRIPTION
#
#   Searches for the library file of the open62541 library [1].
#
#   The open62541 library is a cmake-based project, that supplies both a
#   shared and a static library (with different names). The
#   AX_OPEN62541_CHECK_LIB macro can search for both and adds the first one
#   found to the LIBS Makefile variable. The search can be in either order
#   (shared first or static first), which is selectable on macro invocation
#   with the STATIC-FIRST parameter. The user can change this default by
#   invoking configure with either the --with-open62541-shared or
#   --with-open62541-static option (the named one is checked first).
#
#   Either shared or static library can be excluded from checking completely
#   with the options --without-open62541-shared and
#   --without-open62541-static.
#
#   If the with_open62541 shell variable is set to "no" (e.g. from running
#   the AX_OPEN62541_PATH macro and the user giving configure the option
#   "--without-open62541"), then expands ACTION-IF-NOT-FOUND without any
#   checks. The same is true if both --without-open62541-shared and
#   --without-open62541-static are given.
