# Find the native FLTK includes and library
#
# The following settings are defined
# FLTK_FLUID_EXECUTABLE, where to find the Fluid tool
# FLTK_WRAP_UI, This allows the FLTK_WRAP_UI command to work.
# FLTK_INCLUDE_DIR, where to find include files
# FLTK_LIBRARIES, list of fltk libraries
# FLTK_FOUND, Don't use FLTK if false.
# The following settings should not be used in general.
# 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
