# - Find the native FLTK includes and library
#
# By default FindFLTK.cmake will search for all of the FLTK components and
# add them to the FLTK_LIBRARIES variable.
#
#   You can limit the components which get placed in FLTK_LIBRARIES by
#   defining one or more of the following three options:
#
#     FLTK_SKIP_OPENGL, set to true to disable searching for opengl and
#                       the FLTK GL library
#     FLTK_SKIP_FORMS, set to true to disable searching for fltk_forms
#     FLTK_SKIP_IMAGES, set to true to disable searching for fltk_images
#
#     FLTK_SKIP_FLUID, set to true if the fluid binary need not be present
#                      at build time
#
# The following variables will be defined:
#     FLTK_FOUND, True if all components not skipped were found
#     FLTK_INCLUDE_DIR, where to find include files
#     FLTK_LIBRARIES, list of fltk libraries you should link against
#     FLTK_FLUID_EXECUTABLE, where to find the Fluid tool
#     FLTK_WRAP_UI, This enables the FLTK_WRAP_UI command
#
# The following cache variables are assigned but should not be used.
# See the FLTK_LIBRARIES variable instead.
#
#     FLTK_BASE_LIBRARY   = the full path to fltk.lib
#     FLTK_GL_LIBRARY     = the full path to fltk_gl.lib
#     FLTK_FORMS_LIBRARY  = the full path to fltk_forms.lib
#     FLTK_IMAGES_LIBRARY = the full path to fltk_images.lib
