    2815 # This macro sets up usage of a user library with header files. The assumption
    2816 # is that the header file(s) and library do not reside in standard system
    2817 # directories, hence both the include directory and link flags must be
    2818 # specified. There are two mandatory arguments and two optional arguments.
    2819 #
    2820 # The first argument (mandatory) should be a name (LibraryName) for the
    2821 # library.  The second argument (mandatory) should be an abbreviation in
    2822 # upper case letters (LBRY) for the library. Ultimately, the macro will
    2823 # specify two variables, LBRYINCDIR and LBRYLIB, to be substituted in files
    2824 # generated during configuration; a preprocessor symbol COIN_HAS_LBRY; and a
    2825 # matching automake conditional COIN_HAS_LBRY. LBRYINCDIR should specify the
    2826 # directory containing include files for the library. LBRYLIB should specify
    2827 # the flags necessary to link to the library. A variable coin_has_lbry will
    2828 # be set to true or false, as appropriate. A variable lbry_libcheck will be
    2829 # be set to yes or no; no indicates link checks should not be attempted.
    2830 #
    2831 # The macro defines three configure arguments, --with-libraryname-incdir,
    2832 # --with-libraryname-lib, and --disable-libraryname-libcheck, by converting
    2833 # LibraryName to lower case.
    2834 #
    2835 # LBRYINCDIR and LBRYLIB can be specified as environment variables or as
    2836 # part of the configure command using --with-libraryname-incdir and
    2837 # --with-libraryname-lib, respectively. Command line arguments override
    2838 # environment variables.
    2839 #
    2840 # If a third argument is given, it should specify a file in LBRYINCDIR.  The
    2841 # macro will check for the presence of the file. If a fourth argument is given,
    2842 # it should specify a function name, `fname'.  The macro will attempt to link a
    2843 # trivial program containing a parameterless call to the function, `fname()',
    2844 # using the LBRYLIB flags. The link check uses C as the language; this has been
    2845 # adequate to date but has limitations. It is possible to disable the link
    2846 # check by specifying --disable-libraryname-libcheck. This is a workaround for
    2847 # instances where the link check does not work properly, for whatever reason.
    2848 # If you're trying to link to a Fortran library, consider using F77_FUNC or

    2853 # A fifth argument can be specified to include linker flags that may be required
    2854 # to sucessfully perform the linking check.
    2855 #
    2856 # An optional sixth argument can be given to specify a list of targets.
