# Stuff every FLTK application might need
#
#    If you take this for use in your own project, be sure to change
#    the 'FLTKCONFIG' setting to point to where it's installed
#    on your system. Common examples:
#
#	FLTKCONFIG = /usr/local/bin/fltk-config
#       FLTKCONFIG = /usr/local/src/fltk-1.4.x/fltk-config
#       FLTKCONFIG = ../build/fltk-config # if ../build == CMake build directory
#
#    Set .SILENT in your Makefile if you want 'quieter' builds.
