2397# This macro sets up usage of a user library with header files. The assumption
2398# is that the header file(s) and library do not reside in standard system
2399# directories, hence both the include directory and link flags must be
2400# specified. There are two mandatory arguments and two optional arguments.
2401#
2402# The first argument (mandatory) should be a name (LibraryName) for the
2403# library.  The second argument (mandatory) should be an abbreviation in
2404# upper case letters (LBRY) for the library. Ultimately, the macro will
2405# specify two variables, LBRYINCDIR and LBRYLIB, to be substituted in files
2406# generated during configuration; a preprocessor symbol COIN_HAS_LBRY; and a
2407# matching automake conditional COIN_HAS_LBRY. LBRYINCDIR should specify the
2408# directory containing include files for the library. LBRYLIB should specify
2409# the flags necessary to link to the library. A variable coin_has_lbry will
2410# be set to true or false, as appropriate. A variable lbry_libcheck will be
2411# be set to yes or no; no indicates link checks should not be attempted.
2412#
2413# The macro defines three configure arguments, --with-libraryname-incdir,
2414# --with-libraryname-lib, and --disable-libraryname-libcheck, by converting
2415# LibraryName to lower case.
2416#
2417# LBRYINCDIR and LBRYLIB can be specified as environment variables or as
2418# part of the configure command using --with-libraryname-incdir and
2419# --with-libraryname-lib, respectively. Command line arguments override
2420# environment variables.
2421#
2422# If a third argument is given, it should specify a file in LBRYINCDIR.  The
2423# macro will check for the presence of the file. If a fourth argument is given,
2424# it should specify a function name, `fname'.  The macro will attempt to link a
2425# trivial program containing a parameterless call to the function, `fname()',
2426# using the LBRYLIB flags. The link check uses C as the language; this has been
2427# adequate to date but has limitations. It is possible to disable the link
2428# check by specifying --disable-libraryname-libcheck. This is a workaround for
2429# instances where the link check does not work properly, for whatever reason.
2430# If you're trying to link to a Fortran library, consider using F77_FUNC or
2431# FC_FUNC to obtain a mangled fname appropriate for use from C code. For a C++
2432# library, you're on your own unless the library declares some function with
2433# extern "C" linkage. Otherwise, you'll have to somehow find the mangled C++
2434# name.
2435# A fifth argument can be specified to include linker flags that may be required
2436# to sucessfully perform the linking check.
2437#
2438# An optional sixth argument can be given to specify a list of targets.
2439# For each target X, the variables X_LIBS and X_PCLIBS will be extended by $LBRYLIB,
2440# if the library has been found and seems to work.

3072# This macro checks for the existance of a COIN-OR package and provides compiler and linker flags to compile against this package.
3073# A package can consists of one or more COIN-OR or other projects.
3074# It defines the PACKAGE_CFLAGS, PACKAGE_LIBS, PACKAGE_DEPENDENCIES, and PACKAGE_DATA variables, referring to the compiler and linker
3075# flags to use when linking against this module, the libraries the package depends on, and the directories where the module data resists.
3076# The difference between PACKAGE_LIBS and PACKAGE_DEPENDENCIES is that PACKAGE_DEPENDENCIES does not contain arguments starting with '-',
3077# so it can be used to setup the _DEPENDENCIES variable in a Makefile.am.
3078# It also defines a COIN_HAS_PACKAGE preprocessor macro and makefile conditional.

3083# That is, for each build target X, the variables X_CFLAGS, X_LIBS, X_DEPENDENCIES, X_PCLIBS, X_PCREQUIRES are setup,
3084# whereas the last two specify the values to put into the "Libs:" and "Requires:" fields of the .pc file, resp.
3085#
3086# The first argument should be the name (PACKAGE) of the package (in correct lower

3090# The optional third argument should be a (space separated) list of build targets
