# SYNOPSIS
#
# AX_FLTK(API-VERSION[,
# USE-OPTIONS[,
# ACTION-IF-FOUND[,
# ACTION-IF-NOT-FOUND]]])
#
# DESCRIPTION
#
# This macro checks for the presence of an installed copy of FLTK
# matching the specified API-VERSION (which can be "1.1", "1.3" and so
# on). If found, the following variables are set and AC_SUBST'ed with
# values obtained from the fltk-config script:
#
# FLTK_VERSION
# FLTK_API_VERSION
# FLTK_CC
# FLTK_CXX
# FLTK_OPTIM
# FLTK_CFLAGS
# FLTK_CXXFLAGS
# FLTK_LDFLAGS
# FLTK_LDSTATICFLAGS
# FLTK_LIBS
# FLTK_PREFIX
# FLTK_INCLUDEDIR
#
# USE-OPTIONS is a space-separated set of --use-* options to pass to the
# fltk-config script when populating the above variables.
#
# If you are using FLTK extensions (e.g. OpenGL support, extra image
# libraries, Forms compatibility), then you can specify a set of
# space-separated options like "--use-gl", "--use-images" etc. for
# USE-OPTIONS.
#
# ACTION-IF-FOUND is a list of shell commands to run if a matching
# version of FLTK is found, and ACTION-IF-NOT-FOUND is a list of commands
# to run it if it is not found. If ACTION-IF-FOUND is not specified, the
# default action will define HAVE_FLTK.
#
# Please let the author(s) know if this macro fails on any platform, or
# if you have any other suggestions or comments.
