Dear all, When an autoconf-driven project has a dependency on library foo, what's the best / recommended way to let users specify the directories for header files and library files when configuring the project? For the XWindow system, for instance, there are the --x-includes=DIR and --x-libraries=DIR options, and also --with-x to enable / disable X. I assume it's good to also provide three options for each library: one to let configure know whether it should be enabled or not, i.e. an equivalent of --with-x, and two options to specify the header and library directories. But, of course, it is not possible to define --foo-includes=DIR and --foo-libraries=DIR as is done for X, so is one supposed to use AC_ARG_VAR to achieve this? Many thanks in advance for your recommendations, Sébastien. _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx https://lists.gnu.org/mailman/listinfo/autoconf
