Kitware Robot 7bbaa4283d Remove trailing whitespace from most CMake and C/C++ code 
Our Git commit hooks disallow modification or addition of lines with
trailing whitespace.  Wipe out all remnants of trailing whitespace
everywhere except third-party code.

Run the following shell code:

git ls-files -z -- \
 bootstrap doxygen.config '*.readme' \
 '*.c' '*.cmake' '*.cpp' '*.cxx' \
 '*.el' '*.f' '*.f90' '*.h' '*.in' '*.in.l' '*.java' \
 '*.mm' '*.pike' '*.py' '*.txt' '*.vim' |
egrep -z -v '^(Utilities/cm|Source/(kwsys|CursesDialog/form)/)' |
egrep -z -v '^(Modules/CPack\..*\.in)' |
xargs -0 sed -i 's/ \+$//'

# - 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
