#
# FLTKConfig.cmake - FLTK CMake configuration file for external projects.
#
# This file is generated by CMake and used to load FLTK's settings for
# an external project, i.e. a project using FLTK.
#
# It defines the following variables:
#
# FLTK_VERSION - FLTK version string ("x.y.z")
# FLTK_INCLUDE_DIRS - FLTK include directories
# FLTK_LIBRARIES - list of built FLTK libraries
# FLTK_FLUID_EXECUTABLE - needed by the function FLTK_RUN_FLUID
# (or the deprecated fltk_wrap_ui() CMake command)
#
# It defines the following deprecated variables for backwards
# compatibility (do not use for new projects):
#
# FLTK_INCLUDE_DIR - FLTK include directories (same as FLTK_INCLUDE_DIRS)
#
# Important note: FLTK's CMake build files are not yet complete and may be
# changed in future versions. This includes the list of defined variables
# above that may be changed if necessary.
#
# Note: FLTK 1.4.0 introduced "Modern CMake", therefore usage of most if not
# all of the variables mentioned above is no longer needed in user projects.
# Please use the CMake target names fltk::fltk, fltk::images, etc. instead.
# Please see README.CMake.txt for mor info on how to do this.
#
# Optional: Create backwards compatible aliases for libraries and fluid.
# This is enabled in FLTK 1.4.0 to simplify migration of user projects
# from "classic" (1.3.x) to "modern" CMake and will likely be removed
# in a later FLTK version (maybe 1.4.x, x>2, or 1.5.0).
