Yaakov Selkowitz a6628d154a FindFLTK*: Use Cygwin fltk on Cygwin 
Do not set FLTK_PLATFORM_DEPENDENT_LIBS to contain win32 libraries.
Cygwin builds should use the fltk that comes with Cygwin.

# - Find the native FLTK2 includes and library
# The following settings are defined
# FLTK2_FLUID_EXECUTABLE, where to find the Fluid tool
# FLTK2_WRAP_UI, This enables the FLTK2_WRAP_UI command
# FLTK2_INCLUDE_DIR, where to find include files
# FLTK2_LIBRARIES, list of fltk2 libraries
# FLTK2_FOUND, Don't use FLTK2 if false.
# The following settings should not be used in general.
# FLTK2_BASE_LIBRARY = the full path to fltk2.lib
# FLTK2_GL_LIBRARY = the full path to fltk2_gl.lib
# FLTK2_IMAGES_LIBRARY = the full path to fltk2_images.lib
