# 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.
