doesn't have to have everything in order for FLTK_FOUND to be true.  #7809

# - Find the native FLTK includes and library
# The following settings are defined
#
# 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
# 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.
#
# 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
